(a) Use of Public Sewers Required. The owner of any house, building, or property which is used for human occupancy, employment, recreation, or other purposes and abutting on any street, alley, right-of-way, or easement in which there is or may be located a public sanitary sewer connected to the POTW for the City is required at the owner’s expense to install suitable toilet facilities therein and to connect such facilities by means of a building sewer (lateral) directly to the sewer in accordance with the provisions of this chapter, within ninety days after official notice to do so, provided that the sewer is within 200 feet of the primary structure or house. The owner is responsible for maintenance of the building sewer (lateral) to the point of connection with the publicly owned sewer.
(1) This section shall not apply to any person served by a privately constructed, owned, operated, and maintained wastewater sewer and wastewater treatment facility which discharges directly to an outlet in accordance with the provisions of this chapter and applicable State and Federal laws, further, this section shall not apply to any house, building, or property constructed or under construction prior to the effective date hereof, but this section shall apply to all houses, buildings, or properties, the construction of which is commenced after the effective date hereof.
(2) The City reserves the right to limit connections to sanitary sewers if the existing sewer system or sewage treatment works do not have sufficient capacity for the waste to be discharged from such connections.
(b) Service Connections; Materials of Construction. Service connections shall consist of vitrified clay, soil, cast iron or S.D.R.-35 or American Society for Testing and Materials (ASTM) D3034 of a size not less than four inches nominal, nor more than six inches maximum diameter. Vitrified clay pipe and fittings shall conform to specifications for Extra Strength Clay Sewer Pipe ASTM C-700-7901. Six inch pipe shall be used in new construction.
(c) Joints. Cast-iron soil pipe and fittings shall have all joints properly caulked with oakum and lead.
(1) Vitrified clay pipe and fittings shall have "premium" type joints conforming to Standard Specification for Compression Joints for Vitrified Clay Pipe and fittings (ASTM Designation C425-60T77).
(2) Before the joint is made, both the spigot and the bell shall be thoroughly cleaned to remove any extraneous material and shall be kept clean until the joint is made.
(d) Pipe Bedding. The laying of the pipe in finished trenches shall be commenced at the lowest point so that the spigot ends point in the direction of the flow. All pipe shall be well bedded so that all loads on the pipe shall be equally distributed on the pipe barrel. 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 shall be of 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 pipe shall be removed so that in no case will rock touch any pipe either along the barrel or in bell holes. Where the base of the trench is uneven or stony, sand or gravel shall be used for bedding. The Contractor shall place a bedding cut off trench dam of native clay or impervious soil across and along the trench at a point twenty to thirty feet upstream from the main line sewer wye, tee, or saddle to retard and resist the movement of groundwater through the trench granular bedding or backfill material. The trench dams shall be carefully compacted and shall be three feet in thickness, as measured along the service centerline and shall be constructed against the undistributed trench sides from the subgrade or bottom of the stone foundation, whichever is lower, to the top of granular bedding or backfill to a limit of six inches over the top of the pipe.
(e) Pipe Bedding; Line, Grade and Location.
(1) All pipe shall be laid true to line and grade. Any change in horizontal direction shall be made with long radius curves, one-eighth bends or wye branches.
(2) All pipe shall be laid to a minimum grade of one-fourth inch per foot unless otherwise approved by the Director of Utilities.
(3) No pipe shall be laid closer than three feet to any exterior wall, cellar, basement, well or cistern or less than two feet deep.
(4) A building sewer shall be a minimum of ten feet from any household water supply source and water service line.
(f) Backfill Requirements. After the pipe has been laid and the joint completed, sand, crushed run stone, grits, bank run sand and gravel or selected trench excavation, if approved by the Director of Utilities, shall be placed and tamped along the sides of the pipe and worked under the sides without "lifting" the pipe or causing other movement which will break the joint or cause the pipe to move off alignment. The foregoing material shall be used as backfill to halfway up the pipe. Select earth backfill shall be placed along the sides of the pipe and thoroughly tamped in six inch layers up to the top of the pipe. Then, using select material, the trench shall be backfilled by hand up to a point at least six inches over the top of the pipe. Mechanical or other means of accomplishing the balance of the backfill may then be used for filling the remainder of the trench.
At all trench and excavation locations which are subject to traffic, such as in or across streets, highways and driveways, No. 9 aggregate (Ohio State Highway Specifications) or other suitable materials, properly compacted, shall be used for trench backfill. The pavement shall be replaced with a pavement composed of base and wearing courses equal to the original.
(g) Service Connections.
(1) Tapping existing lines. When service lines are connected to main sewers which have no existing wye branches installed, the contractor shall be required to make the tap using commercially manufactured vitrified wye saddles or cut in PVC wye. The saddles shall have an integrally cast flange that will prevent the saddle from projecting into the main sewer. After the saddle has been installed in the main sewer, the entire joint shall be encased in a minimum of six inches of concrete. Provisions shall be made to prevent the concrete from dropping into the barrel of the main sewer. The entire operation shall be performed only when a City Inspector or Engineer is on the job site.
(2) Service connections at manholes. Where a connection is made to a sanitary sewer at a manhole connection not previously provided for, it shall be made in the wall of the manhole with a smooth channel or pipe constructed to the sewer according to the directions of the Director of Utilities. A tee cleanout shall be used in the mahole; two feet and higher above floor shall require drop pipe secured to wall.
(3) Where a service connection is constructed for a building that is presently discharging sewage into a septic tank or cesspool, the new service connection shall be tapped into the existing service connection with fittings specified in these regulations, and at some point between the building and the septic tank or cesspool. Care shall be taken to insure a tight joint at the connection between the new and existing service connection.
(h) Storm Water Connections Prohibited. No storm water or roof water leader shall be at any time led into or connected with the sanitary sewer or sanitary sewer service connection.
(i) Sewer Elevation. Whenever the elevation of the sanitary sewer is such that it can be done, the service connection shall be brought into the building at such an elevation that it will drain the basement. In all buildings in which the whole or part of the drainage and plumbing system thereof lies below the service connection, the crown of the sanitary sewer shall be connected by gravity in an airtight receiving tank or sump and lifted by artificial means and discharged into the service connection.
