(A) Responsibility for costs. All costs and expenses incident to the installation and connection of the building sewer shall be borne by the owner. The owner shall indemnify the village from any loss or damage to the public sanitary sewer system that may directly or indirectly be occasioned by the installation of the building sewer.
(B) Individual service line required. A separate and independent building sewer shall be provided for every building except that where one building stands at the rear of another on an interior lot, and no building or private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as the building sewer (except for sewer connection charges accruing from the building or properties).
(C) Existing building sewers. Existing building sewers may be used for connection of new buildings only when they are found, on examination and test by the Village Administrator, to meet all the requirements of this chapter and are adequate to serve the purposes of the new building and its use. A sewer connection permit shall be required for all new buildings reusing old sanitary sewer connections. Abandoned connections or building sewers shall be effectively closed or sealed off as directed by the Village Administrator.
(D) Prohibited connections. No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, sump pump discharges, or other sources of surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer.
(E) General construction requirements. The building sewer and the connection of the building sewer into any public sanitary sewer within the jurisdiction of the village and the size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, jointing, testing, and backfilling the trench shall all conform to the material and procedural requirements set forth in the Building and Plumbing Code or other applicable rules and regulations of the village, the village IDM, and in the latest editions of the appropriate specifications of the American Society of Testing Materials, Water Pollution, Control Federation Manual of Practice No. 9, and Standard Specifications for Water and Sewer Main Construction in Illinois, and the requirements contained in this chapter. All the building and private sanitary sewers and connections shall be made gas-tight and watertight. Any deviation from these prescribed procedures and materials must be reviewed and recommended by the Village Engineer and approved by the Village Administrator before installation.
(F) Inspection required. The applicant for the building sewer permit shall notify the Village Administrator when the building sewer is ready for inspection and connection to the public sanitary sewer. No part of a building or private sewer shall be covered until inspected and approved by the Village Building Inspector or his or her designated representative. The connection to the public sanitary sewer shall only be made under the direct supervision of the Building Inspector or his or her representative, and in accordance with the standards of this chapter.
(G) Excavations protected. All excavations for building sewer installation shall be adequately guarded with barricades and lights as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Village Administrator.
(H) Specific construction requirements.
(1) Vertical requirements. Where possible, the building sewer to serve a new building shall be brought to the building at an elevation below the lowest floor or below the lowest plumbing fixture or building drain. The depth shall be sufficient to afford protection from frost and shall, at a minimum, be 42 inches from the ground level to the top of the pipe. The building sewer shall be laid at a uniform grade insofar as possible. Changes in slope shall be made only with properly curved pipe, fittings, or at a manhole facilitating servicing. In all buildings in which the outlet from the lowest plumbing fixture or any building drain is too low to provide gravity flow to the public sanitary sewer, all sewage from the fixtures or building drain shall be lifted by approved mechanical means in accordance with this chapter and discharged into the building sewer. No water-operated sewage ejector pump shall be used.
(2) All basement drains and basement wastewater piping systems shall discharge to the public sanitary sewer system by means of a sewage pump or other mechanical means, and shall not be connected by gravity to the public sanitary sewer.
(3) Horizontal alignment. Insofar as possible, the building sewer shall be laid in straight alignment. Changes in direction shall be made only with properly curved pipe and fittings or at a manhole.
(4) Size and slope. Only the following sizes and minimum slopes of building and private sewers shall be allowed:
Pipe Size | Minimum Slope |
4-inch | 1/4 inch per foot |
5-inch | 1/4 inch per foot |
6-inch | 1/8 inch per foot |
8-inch | 0.006 feet per foot |
(5) Cleanouts. Cleanouts shall be required and installed in appropriate locations in accordance with the State Plumbing Code and shall be constructed in a watertight fashion. Cleanouts shall be capped with a watertight lid to prohibit intrusion of unpolluted water into the public sanitary sewer system. All details of cleanout location and construction for nonresidential users shall be subject to the approval of the village.
(6) Pipe material and joints. All building and private sewers constructed within the jurisdiction of the village and which may, at the time of construction or in the future, be connected to the public sanitary sewer system shall be constructed using the materials specified in the Village of Mahomet’s IDM.
(7) Fittings, couplings and connections. Fittings and couplings shall be made of the same or compatible material as the pipe material or as recommended by the pipe manufacturer. For the connection of two sections of sewer pipe of different sizes or of the same size but different materials, the use of appropriate reducer/increaser or adaptor or pipe coupling specifically made for the coupling of the two pipe sections shall be required. All jointing and connections shall be as recommended by the pipe manufacturer and be made gas-tight and watertight.
(8) Construction of lines. All building and private sanitary sewers shall be constructed in a manner and of materials as set forth by the village IDM. Within public street or alley right-of-way and within areas of present or future pavement or sidewalk, the trench around and above the sewer pipe to the level of the subgrade shall be backfilled with compacted granular backfill and subject to the approval of the village.
(9) Relation to potable water facilities. No building or private sewer shall be constructed in the same trench or within ten feet of a potable water service line. Any part of a public or private sanitary sewer that is located within ten feet of a potable water service line shall be laid in a separate trench and at such an elevation that the top of the sewer is at least 18 inches below the bottom of the water service pipe. If it is impossible to attain the required horizontal or vertical separation, the sanitary sewer shall be constructed of ductile iron or PVC water main pipe and be pressure tested to assure water tightness. Sanitary sewers within 50 feet of a private well for potable water use shall also be constructed of ductile iron or PVC water main pipe.
(10) Connections to public sewers. The connection of any building or private sanitary sewer to the public sanitary sewer system shall be made only at an existing service lateral extended to the property, an existing wye or tee in a main line public sewer, or an existing service stub from a manhole. In the event a service lateral, wye, tee or manhole stub does not exist, a connection may be made to an existing manhole or if an existing manhole does not exist, via installation of a new manhole or by installation of a new wye branch section. The connection of any building or private sanitary sewer to the public sanitary sewer system shall be constructed in a manner and of materials as set forth by the village IDM.
(I) Ownership and maintenance responsibility. Building and private sanitary sewers shall be and shall remain the property of the owner of the lot or parcel of real estate being served and any required repairs, maintenance, or cleaning shall be the responsibility of the property owner. Should, at some future time, the sewer service line be found to be defective, permitting the introduction of storm or ground water into the system, the sewer line shall be repaired at the property owner’s expense so that the entry of storm water or ground water is stopped.
(J) Surface restoration. When existing pavement, sidewalk, yard area, ditches or other surface treatments on public rights-of-way are removed in the course of making a sewer connection, the surfaces shall be restored to meet the original condition in accordance with the Standard Specifications for Water and Sewer Main Construction in Illinois and with the requirements of the village IDM. Street cuts shall be made only at the times and in a manner approved by the village following at least 24-hours’ notice to the village.
