(a) No unauthorized person shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the Village Administrator.
(b) Application for a permit shall be signed by the owner, lessee or agent of the property for which the connection is desired and by the person employed to perform the work, and must describe the property and state the purpose for which the connection is desired. All applications filed after the commencement of the operation of the facilities shall be accompanied by a tap-on fee set forth in Section 921.03. Applications shall be filed with the Fiscal Officer upon a form to be supplied by the Village.
(c) 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 that may directly or indirectly be occasioned by the installation of the building sewer.
(d) A separate and independent building sewer shall be provided for every building; except where one building stands at the rear of another on an interior lot and no 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 one building sewer.
(e) Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Village Administrator to meet all requirements of this chapter.
(f) 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 be as follows:
(1) Size. The minimum size for any building sewer shall be four (4) inches inside diameter.
(2) Grade. The building sewer shall be laid on a straight, uniform and minimum grade of 1%.
(3) Materials. The pipe and joints for any building sewer shall be manufactured of either unplasticized, polyvinyl chloride (PVC) plastic meeting the requirements of ASTM Specification D3034, latest revisions; vitrified clay meeting the requirements of ASTM Specifications C700 (pipe) and C425 (joints), latest revisions; asbestos-cement meeting the requirements of ASTM Specification C644, latest revisions.
(4) Excavation.
A. Except in rock, water-bearing earth, or where a granular or concrete base is to be used mechanical excavation of trenches shall be stopped above the final invert grade elevations so that the pipe may be laid on a firm, undisturbed, native earth bed. If overdigging occurs, all loosened earth must be removed and the trench bottom brought back to grade with granular material.
B. All sewers shall be constructed on firm foundations and the sewer builder shall use such construction methods as may be necessary to prevent settlement of the pipe after it is laid. If, in the opinion of the Village Administrator, the material encountered at the bottom of the trench at the grade of the sewer is unsuitable for foundation, the sewer builder shall excavate to such further depth or width, or shall take such other steps as may be directed by the Village Administrator to provide a good foundation. Authorized excavation below grade shall be filled with suitable material as directed by the Village Administrator.
C. The bottom of the trench shall be carefully graded, shaped and tamped to conform to the outside circumference of the pipe before any pipe is laid. Bell holes, if bell and spigot pipe is used, shall be ample size to permit joints to be made but shall not unduly encroach upon the bottom bearing for the pipe barrel. All rock or stones protruding above the prepared bed of the pipe shall be removed so that in no case will rock touch pipe either along the barrel or in bell holes. Onto this prepared bed the pipe shall be carefully bedded and checked for line and grade.
(5) Pipe Placement.
A. The laying of pipe in finished trenches shall be commenced at the lowest point, with the spigot ends pointing in the direction of flow.
B. Preparatory to making pipe joints, all surfaces of the portions of the pipe to be jointed, or faces of the portions of the pipe to be jointed, or of the factory-made joining material shall be clean and dry. Lubricants, primers, adhesives, etc. shall be used as recommended by the pipe or joint manufacturers’ specifications. The jointing materials or factory-fabricated joints shall then be placed, fitted, joined, and adjusted in such a workmanlike manner as to obtain the degree of water-tightness required. Trenches shall be kept water- free and as dry as possible during bedding, laying, and joining and for as long as period as required.
(6) Backfilling.
A. After the sewer pipe has been laid and the joint completed, care shall be taken in subsequent operations to maintain the pipe to line and grade and to prevent movement. Backfilling operations shall be so conducted as to insure against such movement.
B. Sand, crusher ran stone, grits, bank run sand and gravel, or selected trench excavation, if approved by the Village Administrator, shall be hand-placed and tamped along the sides of the pipe and worked under the sides of the pipe without “lifting” the pipe or causing other movement which will break the joint or cause the pipe to move off alignment. The foregoing described selected material shall be used as backfill around the pipe up to the spring line, halfway up the pipe. Select earth back fill shall then be placed along the sides of the pipe and over the top of the pipe and thoroughly tamped in 6 inch layers until the top of the pipe is covered with 6 inches of select tamped material. Mechanical or other means of accomplishing the balance of the backfill may be used then for filling the remainder of the trench.
C. The trenches and other excavation shall be backfilled with the best of excavated material, in such a manner as will insure the least possible settlement. The backfill and removing of the surplus materials shall follow immediately, on the satisfactory laying of the pipe.
(7) Testing.
A. A test shall be required to demonstrate the water-tightness of the building sewer and shall be made under the supervision and direction of the Village Administrator. The sewer builder shall furnish all labor, equipment and materials required in connection therewith.
B. If the infiltration test is used, the section being tested shall be covered over the sewer pipe with not less than 4 feet of water above the invert of the pipe at the highest point. The infiltration will be measured by means of a weir located in the downstream end of the lateral. The above head of 4 feet shall be maintained for a period of not less than 24 hours before the weir measurement is made.
C. If the exfiltration test is sued, the sewer lateral shall be closed with water until the water elevation in the upstream end of the sewer is not less than 4 feet above the invert of the sewer pipe or 4 feet above the ground water elevation in the trench, whichever is higher. The exfiltration will be determined by measuring the amount of water required to maintain the above-stated water elevation for a period of one hour from the start of the test. The entire length of section to be tested shall be full of water for a period of approximately 24 hours prior to the start of the test.
D. The amount of infiltration or exfiltration as applicable, shall not exceed a rate of 200 gallons per inch of pipe diameter per 24 hours per mile of sewer in each and every section tested.
E. If the low-pressure air test is used for testing, te testing procedure shall be performed in accordance with ASTM Spec. C828-75T or the latest revision. Test pressure shall be from 3 ½ p.s.i. to 2 ½ p.s.i. with allowable air loss of 0.003 cubic feet per minute per square foot of internal pipe surface. All safety precautions as required by ASTM C828 shall be followed when conducting the air test.
F. If the test results do not come to within the limited specified, such work as may be necessary in order to insure conformance, even to the extent of reconstructing the defective section or sections, will be required.
(g) Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the pubic sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer.
(h) No person shall make connection of roof downspouts, exterior foundation drains, areaway drains, or other sources of surface runoff or groundwater to be building sewer or building drain which, in turn is connected directly or indirectly to a public sanitary sewer.
(i) The connection of the building sewer into the public sewer shall be made at the “Y” branch, if such branch is available at a suitable location. If the public sewer is twelve (12) inches in diameter or less, and no properly located “Y” branch is available, a “Y” branch or saddle shall be installed in the public sewer at the location specified by the Village Administrator. Where the public sewer is greater than twelve (12) inches in diameter, and no properly located “Y” branch is available a neat hole may be cut into the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about forty-five (45o) degrees. A forty-five (45o) degree ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or at the higher elevation than the invert of the public sewer. A smooth neat joint shall be made, and the connection made secure and watertight by encasement in concrete. All such connections shall be made gastight and watertight. Special fittings may be used for the connection only when approved by the Village Administrator. The cost of installating the connection shall be included in the owner’s tap-on fee.
(j) 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 sewer. The connection shall be made under the supervision of the Village Administrator.
(k) All excavations for building sewer installation shall be adequately guarded with barricades and lights so 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.
