FOREWORD
The following pages of this Manual contain the design standards and the
administrative requirements for the issuance of sewer permits and outline
the procedures for permit application. The contents of this Manual have
been formulated with the courteous assistance of a Blue Ribbon Committee
representing a cross-section of concerned citizens, local governments,
builders, contractors and consulting engineers, with a view towards facili-
tating the issuance of permits. It is hoped that this Manual will reach, and
be used by, as many hands as may be potentially involved in the preparation
of the permit application and the other plans and documents related thereto.
For if it does, it is our hope that it will properly serve the purposes it is
intended for.
Let me assure you in this connection that the permit and all the entries
therein, together with the other information and documents related thereto,
are individually designed to serve specific and related purposes in our over-
all responsibility for the protection of the health and welfare of the public.
To be specific, the purposes served include: compliance of the project with
the minimum design standards; prevention of pollution by controlling flows
into the District systems, including flows into waters within the District;
prevention of overloading of the District interceptors and treatment plants;
and, equally important, the assistance to the District in planning for the
future to provide for flood control and to meet demands of population growth
as reflected by new construction projects.
Itis our sincere hope that this Manual will prove beneficial to you and that
you will be generous in extending your cooperation and assistance so that,
in turn, we will be able better to serve you and serve and protect the public.

MANUAL OF PROCEDURES
FOR THE ADMINISTRATION OF
THE SEWER PERMIT ORDINANCE
SECTION I - APPLICABLE RULES AND REGULATIONS
Article 1. PERMIT REQUIREMENT
1-1. Purpose. The "Manual of Procedures for the Administration of the Sewer
Permit Ordinance", contained herein, is issued for the implementation, admini-
stration and enforcement of the provisions of The Sewer Permit Ordinance.
The Engineer of Local Sewers is designated as the authorized representative of
the General Superintendent to receive and review permit applications, to inspect
and approve construction under the permit, and to investigate violations of the
Ordinance.
1-2. Permit Requirement. Except as provided in Article 1-3, Exemptions, and
Article 1-4, Waivers, permit is required for all construction of sewers and
sewer facilities within the territorial boundaries of the Metropolitan Sanitary
District, whether such construction is on private or public property. Permit is
also required for existing buildings when the use of the building changes to a use
for which a permit is required. Unless the Ordinance contains clear language
granting a specific exemption as indicated herein, the intent is that no exemption
is granted. It is the responsibility of the General Superintendent to interpret,
administer and enforce the Ordinance within the authority granted to him by the
Board of Trustees.
1-3. Exemptions. A building service sewer (See Article 4-4) constructed to
serve a single building devoted solely for residential purposes and containing
less than twenty-five (25) dwelling units is exempt from the sewer permit require-
ment. Any extention of said service sewer is a violation of the Ordinance.
Any sewer constructed in the public right-of-way or easement, except for crossing,
is considered a lateral and is not exempt from the permit requirement, even
though it may serve a single building containing less than twenty-five (25) dwelling
units. Except as herein provided, all other construction requires a permit.
1-4. Administrative Waivers. The administrative waiver is a procedural
exemption under the Ordinance. Subject to certain requirements, administrative
waivers may be granted by the District to the Permittees for specific types of
non-residential buildings only if those Permittees have complied with the re-
quirements for administrative waivers. Requirements and procedures for ad-
ministrative waivers will be furnished by the District upon request.
1-5. Permittees. The District recognizes as Permittees the parties listed below
as provided in Section 2(h) of the Ordinance. The Permittee is held responsible for
compliance with the conditions of the permit.
a. Any municipality, municipal corporation, sanitary district, utility company,
township government or any other governmental body.
b. Any municipality, municipal corporation, sanitary district, utility company,
township government or any other governmental body jointly with any individual,
individuals or corporation where application is made for installations on private
property.
C. Any individual, individuals, or corporation who owns property directly
adjacent to an interceptor sewer of The Metropolitan Sanitary District of Greater
Chicago, where direct connection to said interceptor is made or is contemplated
by the owner of said property for the sole, exclusive and perpetual use of the owner
of said property (and where the direct connection serves only that property immedi-
ately adjacent to said interceptor), who seeks permission to discharge sewage,
industrial waste or other waste into facilities of The Metropolitan Sanitary District
of Greater Chicago.
d. Any individual, individuals or corporation who provides an acceptable
sewage treatment plant for the sole, exclusive and perpetual use of the owner of
the property being served thereby, which discharges into any waters or intercep-
tor sewer of The Metropolitan Sanitary District of Greater Chicago in conformity
with the Ordinances of The Metropolitan Sanitary District of Greater Chicago, the
Rules and Regulations of the Illinois Sanitary Water Board and the Statutes of the
State of Illinois.
e. Any responsible individual, individuals, or corporation, (not otherwise
qualified as permittee under the provisions of Section 2(H)2, 3 or 4 of the Sewer
Permit Ordinance), upon presentation of satisfactory evidence of responsibility
as determined by the Board of Trustees, where construction of sewers or
sewerage systems is contemplated to serve property owned by said individual,
individuals, or corporation, in an unincorporated area, and the contemplated
construction is intended for the sole, exclusive and perpetual use of the owner;
provided that said unincorporated area is outside the jurisdiction of a local
sanitary district and outside the area of a public utility company certificated for
such service, and the township government declines to execute the permit
application and to assume the obligations of a joint permittee, as provided in
Section 2(H)2 of the Sewer Permit Ordinance.
1-6. Joint Permittees. In addition to those cases where the requirement for joint
permittee is mandatory under the Ordinance, permits may be issued to joint permit-
tees if so requested by the local governmental body having jurisdiction.
Amended 10/26/72 2
1-7. Permittees Under Previous Ordinance. Nothing contained in Article 1-5 shall
operate to annul permits previously issued for the construction of sewers under the
Ordinance then in effect, except that in unincorporated areas where a permit had
been issued to an individual owner as Permittee, if said owner -Permittee shall
abandon, or transfer the ownership of, the sewer system constructed under a per-
mit and the area served becomes subsequently incorporated or is annexed to a duly
constituted local government, sanitary district or utility company, the local authority
assuming jurisdiction over the area shall thereby become the Permittee for said sys-
tem and shall thereafter be responsible for the proper maintenance and operation of
the system.
1-8. Definitions. For the purposes of the Metropolitan Sanitary District, the fol-
lowing definitions shall apply:
a. "Sewage" means water -carried human wastes or a combination of water -
carried wastes from residences, business buildings, institutions and industrial
establishment, together with such ground, surface, storm or other wastes as may
be present.
b. "Industrial Waste" means the solids', liquids or gaseous waste resulting
from any industrial, manufacturing, trade or business process or from the develop-
ment, recovery or processing of natural resources.
C. "Other Wastes" means all decayed wood, sawdust, shavings, bark, lime,
refuse, ashes, garbage, offal, tar, chemicals and other substances except sewage
and industrial wastes..
d. "Maintenance" means keeping the, sewer lines, sewer systems, sewer
facilities or sewage works and structures in satisfactory working condition and
good state of repair, (including but not limited to preventing any obstructions or
extraneous materials or flows'from entering said facilities, protecting said facili-
ties from any damage, and keeping same free from defects or malfunctions), and
making necessary provisions and taking necessary precautions to assure that said
sewer facilities are at all times capable of satisfactorily performing the services,
and adequately discharging the functions and producing the final results and purposes
said facilities are intended to perform,discharge or produce.

3-3. Drop Manholes. An exterior drop pipe should be provided for a sewer enter-
ing a manhole at an elevation of 24 inches or more above the manhole invert, as
provided in the rules and regulations of the Illinois Sanitary Water Board. The
minimum diameter of a drop manhole shall be 48 inches. The diameter of the
drop pipe shall preferably be larger than, or of the same diameter as, the entering
sewer. The minimum diameter of the drop pipe shall not be smaller than the dia-
meter of the entering sewer by more than two nominal diameters (e. g, for 12",
15" and 18" entering sewer, the drop shall be 8", 10" and 12" respectively), pro-
vided that the minimum diameter of the drop pipe shall not be less than 8". If a
smaller drop is desired, design calculations and configurations shall be submitted
for review and approval.
5.
3-4. Protection of Water Mains. Water mains shall be protected in accordance
with the requirements of the Illinois Sanitary Water Board. Where a sewer main
lateral or building service sewer crosses a water main, a minimum vertical sepa-
ration of 18" shall be provided between the top of the lower pipe and the bottom of
the upper pipe. Where the 18" vertical separation is not provided, the sewer shall
be constructed of cast iron or ductile iron pipe or shall be encased in concrete for
a minimum distance of 10 feet on each side of the water main.
3-5. Materials. All materials shall conform to the applicable ASTM, ASA or
other national or accepted standards. When the materials indicated below are
specified by the design engineer, the pipe joints shall conform to the specifications
shown, for sanitary sewer work in separate areas and for all sewer work in com-
bined areas;
Material Joint
a.
Vitrified Clay Pipe
ASTM C-425
b.

Nothing contained in this Article shall be interpreted to mean nor imply an endorse-
ment by the Metropolitan Sanitary District of any material over another, nor an opinion
by the District regarding the equality or superiority of the performance qualities of
any of the materials.
3-6. Workmanship. As a minimum requirement all sewer pipes shall be laid in
accordance with the applicable ASTM specification. The specifications for the con-
struction of any sewers within the District shall not be less stringent than the "Stan-
dard Specifications for Water and Sewer Main Construction in Illinois" (The Red
Book), adopted by a joint committee of the Illinois Society of Professional Engineers,
Consulting Engineers Council of Illinois, Illinois Chapter of The American Public
Works Association, Illinois Municipal League and The Associated General Contrac-
tors of Illinois. A copy of said specifications is obtainable from the organizations
mentioned.
3-7. Design FIow. Average design flow for sanitary sewer shall be 100 gpcpd. Maxi-
mum design flow for sanitary sewer lines shall be determined by one of the equations
indicated below; provided, however, that the maximum design flow for sewer laterals
need not exceed 400 gpcpd and the maximum design flow for sewer mains and trunks
shall not be less than 250 gpcpd.
Equation 1. Q = 500
(P)VS
Equation 2. Q =100 (I + 14��
4+ Vr ) "Where
Q = Maximum design flow, gpcpd
P = Population in thousands
6.
3-8. Curvilinear Sewer. Available information based on field data falls short
of providing conclusive evidence in support of the practice of curvilinear align-
ment for sewers 24" or less in diameter. Where local governments elect to per-
mit the construction of curvilinear sewer, it is mandatory that available mainte-
nance equipment be evaluated and proper equipment acquired.
When permitted by the local government, construction of sewers 24" or less in
diameter on curvilinear alignment shall be subject to the following criteria.
a. Ali%nment: Alignment shall follow the general alignment of the street.
Curvilinear sewer alignment shall be limited to curved street areas.
b. Curvature: Only simple curves may be used.
C. Radius: Minimum radius shall be no less than 200 feet.
d. Minimum Slope: The minimum slope shall be that which produces
a minimum velocity of 2.0 fps (Hydraulics of curvilinear alignment to be taken
into account. )
e. Manhole Location: Manholes are required at the point of beginning and
at the end of the curve and at the point of inflection, (PC, PT and PRC).
f. Deflection: Deflection of pipe shall not exceed the maximum deflection
recommended by the joint manufacturer. The deflections shall be uniform and the
finished installation shall follow a smooth curve.
7.
Article 4. 'SUPPLEMENTAL DESIGN REQUIREMENTS.
4-1. Overhead Plumbing, After December 31, 1970, all new buildings with base-
ments, floors, rooms or occupancy areas below ground level at the building site
and served by a public or private sewer system, shall have overhead plumbing. No
permit application will be accepted, nor any permits issued after December 31,
1970, to any municipality or local government unless said municipality or local
government shall have adopted an ordinance requiring overhead plumbing, and a
copy of said ordinance shall have been filed with the Metropolitan Sanitary District,
or that the permittee and/or co -permittee shall agree to comply with the require-
ments of this Article.
4-2. Datum. The datum shall be indicated on the plans submitted. All plans shall
preferably be based on the Chicago City Datum which is established as:0. OOC. C. D. _
579.48 ft. above Mean Sea Level (1929 Adjustment) or 579. 88 ft. above Mean Tide

plans to relate the datum used to the Chicago City Datum.
4-3. Pipe Bedding. Bedding, other than concrete embedment, shall consist of
gravel, crushed gravel, pea gravel, crushed stone or crushed slag, 1/4" to 3/4" in
size. As a minimum, the material shall conform to the requirements of Article 704. Ol
of the "Standard Specifications for Road and Bridge Construction", of the State of
Illinois or ASTM C-33. The gradation shall conform to gradation CA 7, CA 8, CA 11
or CA 13 of the Illinois Standard Specifications or to ASTM Gradation No. 67. The
pipe shall be laid so that it will be uniformly supported and the entire length of the
pipe barrel will have full bearing. No blocking of any kind shall be used to adjust
the pipe to grade except when used with embedment concrete. Bedding shall be
required for all sewer construction, except ductile iron pipe, and shall be of a
minimum thickness equal to 1/4th of the outside diameter of the sewer pipe but
shall not be less than four inches (4").
4-4. Building Service Sewer. Building service sewer is defined as a sewer pipe
receiving flow from a single building and connecting to a sewer main or lateral,
and constructed on private property, except for street crossing. The maximum
length of a building service sewer shall preferably be 120 ft. and shall not exceed
150 ft. If the length is exceeded an intermediate manhole shall be built. A manhole
or clean-out shall also be installed every 150 ft. When the building service sewer
connects to a sewer lateral of a size not larger than the size of the service sewer,
a manhole shall be built at the point of connection.
Minimum design standards, and other requirements hereof, governing materials,
joints, infiltration, workmanship and maintenance for sewer mains and laterals
shall also apply to building service sewers. Horizontal and vertical alignment of
the service sewer shall be uniform and shall follow a straight line alignment. There
shall be no dips in the grade or fall in the line. Turns or bends required for the
riser, if any, or necessary to connect to the sewer wye or tee, shall be made with
standard bends.
In those instances where the building service sewer is partially constructed from
the sewer lateral or main to a point other than the building to be served, the pipe
shall be tightly plugged using a manufactured plug. The plug shall be pre -wired
by the manufacturer so that it can be firmly secured in place.

4-5. Connection of Building Service Sewers to Sewer Mains. Building service
sewer shall generally enter the sewer main or lateral by way of an existing wye
or tee. In the event of absence of the wye or tee, the connection to the sewer main
or lateral shall be made by one of the methods indicated below. If another method
is desired, a detail shall be submitted for review and approval by the District be-
fore the connection is made. Indiscriminate breaking of the sewer main pipe is
not allowed.
a. Installation of a manhole.
b. Circular saw -cut of sewer main by proper tools ("Shewer-Tap" machine
or similar), and proper installation of hub wye saddle or hub tee saddle, in accor-
dance with manufacturer's recommendations.
c. Remove an entire section of pipe and replace with a wye or tee branch
section. Pipe section shall be removed by breaking only the top of one bell. After
the wye or tee branch is inserted, concrete shall be placed over the broken area
to a minimum thickness of 4" and to a dimension of 8" in all directions.
d. Using pipe cutter, neatly and accurately cut out desired length of pipe
for insertion of proper fitting. Use "Band -Seal" couplings, or similar couplings,
and shear rings and clamps to fasten the inserted fitting and hold it firmly in
place. Follow manufacturer's recommendations for the installation.
4-6. Inspection Manholes. An inspection manhole having a minimum diameter
of 48" is required for all commercial and industrial buildings. The manhole shall
be constructed on the building service sewer before it connects to the sewer main,
and preferably shall not be closer than five (5) ft. to the building. There shall be
no flow into the inspection manhole except flow from the building or buildings
for which the inspection manhole is intended. Manholes constructed on public
sewer, or on sewers receiving other flows, are not considered inspection man-
hole s.
4-7. Sound Engineering Practice. The design and supplementary design require-
ments contained herein do not replace and are not a substitute for sound engineer-
ing practice nor the professional ability and judgement of the design engineer.

Article 6. STORM WATERS.
6-1. Separation of Storm Waters and Sanitary Sewage. Except as provided in
Article 6-2 below, all new sewer construction shall provide two separate and dis-
tinct sewer systems as follows:
a. Storm Sewer Systems. The system shall be for the collection and con-
veyance of surface run-off and other storm waters. All storm waters shall be
collected and conveyed in a pipe or ditch system to the point of discharge in the
receiving natural or man-made stream or drainage ditch. No storm waters shall
be allowed to enter the sanitary sewer systems except that in "Combined Sewer
Areas" only, the storm waters are allowed to be discharged into the MSD inter-
ceptors.
b. Sanitary Sewer Systems. The system shall be for the collection and
conveyance of sanitary sewage consisting of domestic and other water -borne wastes.
All sanitary sewage shall be collected and conveyed in a pipe system to the point of
discharge into an existing sanitary sewage system, MSD interceptor or treatment
plant. No sanitary sewage shall be allowed to enter any storm sewer system or
discharge onto the ground or into receiving streams, without first having been
treated.
6-2 Combined Sewer Areas. In areas designated as "Combined Sewer Areas" on
the Metropolitan Sanitary District maps, the following requirements shall apply:
a. Separation. Complete separation of sewers shall be provided within
the property lines.
b. Detention. Detention shall be provided and/or permanent constrictions
shall be built on the storm sewer system to control the flow into the existing com-
bined system in accordance with the requirements of the local government.
C. Down -Spouts. All down -spouts or roof drains shall discharge onto the
ground or be connected to storm or combined sewer. No down -spouts or roof
drains shall be connected to the sanitary sewers.

discharge shall be made into storm sewers, combined sewers or drainage ditches.
No footing drains or drainage tile shall be connected to the sanitary sewer. After
December 31, 1970 all new construction shall conform to the requirements of this
paragraph. No permit application will be accepted, nor any permits issued after
December 31, 1970 to any municipality or local government unless said municipality
or local government shall have adopted an ordinance reflecting the requirements of
this paragraph and a copy of said ordinance shall have been filed with the Metropo-
litan Sanitary District, or that the permittee and/or co -permittee shall agree to
comply with the requirements of this Article.
Amended 3-25-71 it.
e. Floor Drains. Floor drains in basements shall be connected to sump
pumps and discharged to the sanitary or combined sewers.
f. Sump Pumps. Sump pumps installed to receive and discharge ground
waters or other storm waters shall be connected to the storm or combined sewers

mit application will be accepted, nor any permits issued after December 31, 1970, to
any municipality or local government unless said municipality or local government
shall have adopted an ordinance reflecting the requirements of this paragraph and a
copy of said ordinance shall have been filed with the Metropolitan Sanitary District,
or that the permittee and/or co -permittee shall agree to comply with the require-
ments of this Article.
C. Floor Drains. Floor drains in basements shall be connected to sump
pumps and discharged to the sanitary sewers.
d. Sump pumps. Sump pumps installed to receive and discharge ground
waters or other storm waters shall be connected to the storm sewer or discharge
into a drainage ditch. Sump pumps installed to receive and discharge floor drain
flow or other sanitary sewage shall be connected to the sanitary sewers. A sump
pump shall be used for one function only, either the discharge of storm waters or
the discharge of sanitary sewage.
e. Completion of Storm Sewer System. The construction of the proposed
storm sewer system shall be completed before the sanitary sewer system is put
in service. When compliance with this requirement may cause an undue hardship
to the Permittee, the Permittee shall so notify the District and the District may
waive this requirement if the conditions so warrant.
f. Window Well and Area -Way Drains. No window well or area -way drains
shall be connected to the sanitary sewer.
Amended 3-25-71/10-26-72 12.
6-4. Storm Water Detention in Unsewered and Separate Sewered Areas
a. General. It is recognized that the receiving streams within the District
do not have the capacity to receive and convey the increased storm water runoff
resulting from rapid urbanization occurring in many areas. These receiving streams
are subject to frequent flooding which results in a growing rate of property damage.
It is the intent of Section 3(B) of the Sewer Permit Ordinance to encourage local
governments and developers to jointly participate in providing detention storage
to eliminate the excessive runoff during heavy storm periods. Where impervious
areas are planned or contemplated, it is the intent that detention be provided as
required by the provisions hereinafter set forth. It is proposed that well maintained
landscaped areas would be provided to act jointly as detention reservoirs and
recreation facilities or aesthetic focal points in new village parks, either in
incorporated or unincorporated areas, forest preserve areas, county parks, housing
developments, shopping centers, industrial parks, etc. Other control methods to
regulate the rate of storm water discharge which would be acceptable include detention
on flat roofs, parking lots, streets, lawns, underground storage, oversized storm
sewers with restricted outlets, etc.
It is recognized that in order to better serve the long-range interests of the local
communities and the Metropolitan area, comprehensive basin -wide planning for
flood control should be formulated, adopted and implemented. Comprehensive
planning is far more beneficial than the proliferation of small, on-site detention
areas, although on-site detention does provide protection and is acceptable for
compliance with this Ordinance. The District may be called upon by the local
governments to render advisory, technical and other assistance for the formulation
and implementation of a drainage plan.
b. Requirements. Pursuant to the provisions of Section 3(B) of the Sewer
Permit Ordinance, a sewer permit will not be issued after January 1, 1972, unless
(1) The permittee (governmental body) has adopted a Storm Water Detention or Flood
Control Ordinance acceptable to the District, and has on file with the District, an
approved drainage plan and schedule for its implementation, or (2) The permittee
or co -permittee provide detention of storm water runoff as set forth in the following
criteria.
(1) Allowable Release Rate. The release rate of storm water from all
developments requiring detention shall not exceed the storm water runoff from the
area in its natural undeveloped state.
Because of the flat conditions of the land in this area, channel configurations cut
by nature are generally unable to handle the runoff from high intensity rainfalls
and results in flood plain storage or spreading of runoff over the land areas during
the larger storm periods. In order not to increase the runoff from such areas after
Amended 5/27/71,10/26/72, 4/17/75
13.
development, the release rate must be limited to the carrying capacity of these
natural channels.
The District will accept the release rate of not greater than that calculated from
a storm of three (3) year frequency with a runoff rate coefficient of 0. 15, unless
the applicant can show by his detail calculations, which are acceptable to the
District, that the discharge rate of the natural outlet channel serving the area is
greater.
(2) Bypass. Drainage systems shall have adequate capacity to bypass
through the development the flow from all upstream areas for a storm of design
frequency assuming that the land is in a fully developed state under present zoning
or zoning proposed under a Comprehensive Plan. The bypass flow rate shall be
computed utilizing a runoff coefficient of not less than 0. 35. An allowance will be
made for upstream detention when such upstream detention and release rate has
previously been approved by the District and that evidence of its construction can
be shown.
(3) Design Storm. The live detention storage to be provided will be cal-
culated on the basis of the 100 -year frequency rainfall as published by the U. S.
Weather Bureau for this area. The detention volume required will be that necessary
to handle the runoff of a 100 -year rainfall, for any and all durations, from the fully
developed drainage area tributary to the reservoir, less that volume discharged
during the same duration at the approved release rate.
c. Exemptions. Under the provisions of this article, storm water detention
facilities meeting the criteria and requirements established herein are not required
by the District for the following projects, provided that the available outlet capacity
is adequate as determined by the Municipal Engineer. If the outlet capacity is not
adequate, then detention as determined by the Municipal Engineer will be required
to store that portion of the runoff exceeding the outlet capacity. .
(1) Residential subdivisions, the plats for which were recorded prior to
January 1, 1972. If the subdivision or any part thereof is resubdivided, this
exemption shall cease. When a permit application is made to the District pursuant
to this exemption, the submittal must include a copy of the land plan and the plat of
subdivision or resubdivision, as approved by the municipality. The land plan must
show all the proposed layout and the intended use of the entire area involved.
(2) Non-residential projects having a total area of less than five acres.
(3) Residential non -single family projects having a total area of less than
five acres.
acres.
(4) Residential single-family projects having a total area of less than ten
14.
*d. Special Provisions:
(1) Multiple Outlets. In order to eliminate small multiple outlets,
generally designs requiring a release pipe of less than four (4) inches in diameter
are not acceptable.
(2) Affidavit of Disclosure of Property Interest.
(a) As part of the submittal documents, for projects in the separate
sewered areas, the owner of the property upon which the project (for which the
permit application is made) is located, shall furnish in all instances an Affidavit of
Disclosure of Property Interest stating the aggregate total area of said property
and all other lands contiguous to said property in which the owner holds an interest.
The applicability of the detention requirements will be based on the total contiguous
area in which an interest is held by the owner.
(b) Where a permit application is made for sanitary sewer and the
area serviceable by the sewer is under the control of an individual or a legal entity
(directly or indirectly, in part or in full), the area of the project (for the purpose
of determining the applicability of the detention requirements) shall be considered to
be the total area owned or controlled by the applicant, and detention facilities or
provisions shall be made as part of the permit for the total area.
If the area serviceable by the sewer is not in its entirety under the control of the
applicant, the applicant shall be responsible to provide detention facilities only
for that part of the area which is under his control.
(c) In all instances where the property which is the subject of a permit
is less than five (5) acres (or less than ten acres for residential single family
projects) and detention is not provided as part of the permit, the applicant shall
furnish to the District, as part of the submittal, an Affidavit of Disclosure of
Property Interest with respect to the property, which is the subject of the permit
stating that:
(i) The owner of the property has no interest, nor did he have any
interest at any time during the previous two years in any land contiguous to said
property, such that the aggregate total area of the property and the contiguous lands
exceeds five (5) acres.
(ii) The owner covenants and agrees that if within two years
after the issuance of the permit he acquiree any interest in lands contiguous to
the property such that the aggregate area of the property and the contiguous lands
exceeds five (5) acres, the owner shall provide for storm water detention for the
entire aggregate area.
'-Amended 4-17-75; Effective Date: July 1, 1975
15.
(iii) No owner of any lands contiguous to the property has any
interest in the property such that the aggregate total area of the property and the
contiguous lands exceeds five (5) acres.
For the purpose of this article, the following definitions shall apply:
Owner: means record title holder or a beneficiary of a land trust which
is the record title holder, and includes singular and plural; if the owner is other
than an individual, the term includes beneficiaries, agents, shareholders, officers
and directors.
Ownership: means holding of record title or any beneficial interest.
Interest: means property interest or contractual interest, legal or
equitable, directly or indirectly, in part or in full, and includes option to buy.
In the case of a shareholder interest, the shareholder shall be deemed to have an
interest if he owns or controls 5% or more of the shares.
Contiguous: means adjacent to and touching at one point or more; if the
lands are separated by an easement or a dedicated right-of-way, it shall be
considered contiguous.
(3) Recording: Under special and unusual circumstances, where conditions
so warrant as solely determined by the District (generally where sewer connections
are not proposed), the District may issue the sewer permit without detention being
provided for the entire area as part of the submittal and place a special condition
on the permit that on-site detention will be provided for each future project within
the area regardless of the area of the individual future project, provided that a
Notice of Requirements for Storm Water Detention in connection with the permit
issued by the District shall be recorded with the Cook County Registrar of Torrens
Titles or the Recorder of Deeds of Cook County, as an encumbrance against the
entire area.
Before such permit is issued by the District, the applicants shall furnish as part
of the submittal, preliminary plans and design showing in adequate detail the
manner in which the detention requirements will be satisfied by future projects
within the area which is the subject of the permit. If, as part of the preliminary
plans and design, it is proposed that the detention requirements will be satisfied by
providing on-site detention facilities for individual future projects, the facilities
shall be designed such that the minimum size of the area served by such facilities
shall not be less than three (3) acres. The areas for which the detention facilities
are designed shall be delineated on the preliminary plans. If individual lots having'
an area of less than three (3) acres each are proposed for development in the future,
such lots shall be jointly developed so that the minimum area for which detention
16.
facilities are designed and provided shall not be less than three (3) acres.
Individual projects developed within the area which is the subject of the permit
shall conform to the preliminary plans made a part of the permit with respect
to providing detention facilities to satisfy the detention requirements or provide
alternate design meeting the intent of the preliminary plans and of the detention
requirements as outlined herein.
Where only the name of the permittee appears on the permit application, the
permittee shall furnish to the District as part of the submittal an affidavit that the
permittee is aware of the above requirements and will require any person connecting
to the sewer which is the subject of the permit to comply with these requirements.
Permits issued under the provisions of this article will contain a condition to the
effect that the permittee will require any person connecting to the sewer to comply
with the requirements contained herein.
*6-5. Correction of Existing Deficiencies in Separate Sewered Areas
In order to reduce overloading of separate sanitary sewers by eliminating
illegal connections and other deficiencies, the following requirements shall be
observed:
a. Within one year of the effective date of this amendment, all permittees
in separate sewered areas outside the City of Chicago shall inspect all structures
within their jurisdiction or control and ascertain whether any downspouts or roof
drains are connected directly or indirectly to sanitary sewers. Any such illegal
connections shall be corrected by causing such downspouts to discharge to the
ground, or to authorized storm sewers, wet wells or ditches. Such legal action
as may be required to the effect the necessary corrections shall be the responsibility
of the appropriate permittee.
b. Within one year of the effective date of this amendment, all permittees
having jurisdiction over separate sanitary sewer systems shall visually inspect
said systems to ascertain the location of sources of storm water entry to the
systems, such as (but not limited to) (1) leaking manholes, manholes having
open grates or loose frames, or manholes located in low points or ditches;
(2) failure to install lock -type, watertight manhole frames and lids in flood hazard
areas; (3) cracked or broken pipes at manholes; (4) illegal storm water inlets or
connections; (5) problems at creek or ditch crossings or at points of storm sewer
cross -connections and overflows. Such permittees shall also make inspections
during dry and wet weather periods for purposes of comparison to determine
points of storm water entry into their systems. Any sources of storm water
entry to the sanitary sewer systems discovered in the course of said inspections
shall be repaired and corrected, including such steps as may be necessary to
remove footing drains, areaway drains, window well drains, and other illegal
connections of storm water sources to the sanitary sewer systems. Such legal
action as may be required to effect the necessary corrections shall be the
responsibility of the appropriate permittee.
"Effective January 1, 1973

of the building and certifying that no industrial waste will be allowed to discharge
into the sewe r system.
C. Industrial Waste Present. When the use of the building involves processes
or operations that will produce industrial wastes (e. g. pickling plant), submit the
additional items below:
1. A statement on the owner's stationery describing the use of the
building and the processes used.
2. Indicate quantity, character and quality of industrial wastes produced.
Indicate 5 -day BOD, pH; suspended solids, etc. (See MSD Sewer User Form)
3. Indicate type and location of treatment facilities proposed and the
expected quality of the effluent. (See also Article 8-5)
4. Indicate method of controlling the quantity of discharge into the pub-
lic sewer and times of discharge.
5. Indicate other wastes created but not discharged into the sewer and
the method of disposal of same.

8-5. Treatment Facilities. Treatment facilities under this article, include by way
of description and not enumeration, treatment processes, treatment plants, oxida-
tion ponds and similar facilities. When the project involves, or consists of, treat-
ment facilities, submit the items indicated below. In all cases, the design engineer
should consult with the Sanitary District before final design is completed:
a. Permit form, location map and other relevant data as may be required.
(See Article 7-1)
b. Contract drawings.
C. Design criteria and calculations.
d. Required maintenance bond.
8-6. Lift Stations. Gravity sewers are by far preferable to Lift Stations and force
mains as a means for conveying sewage. In general, lift stations are not desirable
nor recommended and should be resorted to only after all other engineering studies
have been exhausted. Force mains should preferably be designed to discharge into
gravity sewers. Discharge of force mains into another lift station is discouraged
and is considered to be potentially detrimental to the health and welfare of the pub-
lic served. Where a force main or a lift system is designed to discharge into another
lift station a detailed report is required to justify such design. The report should
include other methods considered, and the recommendation for the design must be
supported by engineering considerations. Written approval of the Owner of the
receiving lift station and a copy of the maintenance and operation agreement between
the parties must be furnished. The agreement shall also clearly specify the respon-
sibilities of the parties in case of failure of either lift station.
Where the project for which a permit application is made consists of, or involves
a lift station and force main or lift system, submit the following:
a. Pe rmit form, location map and other relevant data as may be required.
(See Article 7-1)
b. Contract drawings.
C. Plan and profile of force main.
d. Design calculations and alternate power available. (Complete special
MSD form for this purpose. )
e. Map of area to be served, clearly delineated.

SECTION IV - CONSTRUCTION, TESTING AND APPROVAL
Article 9. CONSTRUCTION AND INSPECTION
9-1. Advance Notice. Prior to commencement of sewer construction under the
Permit, the Permittee shall give, or cause to be given, to the District, an advance
notice of at least two (2) working days.
9-2,. Conformance to Plans and Specifications. All construction shall be in
accordance with the plans and specifications made part of the Permit. The permit,
together with a set of the plans and specifications for the project shall be kept on
the job site at all times during construction, until final inspection and approval by
the District.
9-3. Construction Inspection. All sewe r construction shall be inspected and approved
by a Registered Professional Engineer acting in behalf of the Permittee or the Owner
of the project, or by the duly authorized representative of the Professional Engineer.
No sewer trenches shall be backfilled except as authorized by the Inspection Engineer
after having inspected and approved the sewer installation. The Inspection Engineer
shall signify his approval and authorization for backfilling on the Inspection Report.
The Inspection Report shall be on the job site at all times, and shall bear the signa-
ture of the Engineer, identifying those portions of the sewer inspected and approved
by him. The Inspection Report shall be made available for review by the District
representative.
9-4. "As -Constructed" Drawings. Within sixty (60) days after final inspection and
approval by the District, the Permittee shall furnish or cause to be furnished to the
District, a set of "As -Constructed" drawings. The pipe and joint materials and
applicable ASTM Specifications shall be indicated on the drawings.
Article 10. TESTING AND APPROVAL
10-1. Requirement for Testing. All sewers constructed under permits issued by the
District shall be subject to inspection, testing and approval by the District to insure
compliance with the applicable requirements. All testing shall be made or caused to
be made, by the Permittee at no cost to the District and in the presence of the District
representative.
10-2. Request for Final Inspection. Upon completion of construction, the Permittee
shall submit to the District a properly executed request for final inspection and appro-
val on the form prescribed by the District. No sewer shall be put in service until it
has been approved by the District, and until all the conditions of the permit have been
satisfactorily met.
24.
10-3. Construction Without Advance Notice. Construction without advance notice to
the District, as provided in Article 9-1, shall be considered prima facie evidence
that construction may not have been done in accordance with the applicable require-
ments. In addition to any other requirements, that portion of the sewer construct+ ,,
prior to the notification of the District shall be exposed by the owner, at his expense,
in at least one location between every two manholes, two terminal points or as directed
by the District for visual inspection by the District to insure compliance with applicable
requirements as to materials and workmanship.
10-4. Maximum Allowable Infiltration. It is the intent of the District that all sewers
within its territorial boundaries shall be constructed of sound material and shall be
properly jointed so that the amount of ground water infiltrati� n into the sewer shall
be kept at a minimum. The maximum allowable rate of infiltration or exfiltration
shall not exceed 500 gallons per twenty-four (24) hours per mile per inch -diameter
of the sewer pipe, for any section of the system and at any time during its service
life.
