(a) Permit and License.
(1) Sewer permit. No private or public sanitary or storm sewer drain or lateral for any purpose shall be constructed, nor shall any connection be made to any such sewer, drain or lateral until a written permit from the Building and Zoning Division is obtained by the person proposing to or employed to perform the work. The application for a permit shall be signed by the owner, lessee or agent of the premises for which the connection is desired and by the person employed to do the work. The application shall be on a form furnished by the Building and Zoning Division and shall describe the premises by lot number or metes and bounds, shall state the specific purpose for which the connection is desired and shall locate the connection or the sewer to be tapped and the sewer, drain or lateral to be constructed. The applicant shall state the nature of the wastewater to be discharged and shall, if requested, furnish written proof to the satisfaction of the Chief, I.P.P. that the wastewater meets all the requirements of this Chapter. The person to whom a permit is issued shall be held responsible for the proper installation of the building sewer in accordance with all applicable regulations. The person to whom a permit is issued shall be responsible for obtaining any permit to work in any streets, highway, etc., from the City or other appropriate authority. A permit shall not be issued until all the provisions of this Chapter have been satisfactorily met. This section shall not apply to work done by City employees or work done under the items of a written contract with the City.
(2) Sewer installer license required. All connections to a public sanitary sewer shall be made by a licensed sewer installer. To obtain a sewer installer's license the applicant shall take a written and practical examination. The written examination shall be given through the City of Ashland's Building and Zoning Office. The inspection portion of the license examination shall be done by the Building and Zoning Office or the Engineering Office of the City of Ashland. The applicant shall answer correctly at least 70 percent of the written examination. The written examination shall be 50 percent of the sewer installer's test with the first inspection of a sewer tap and sewer lateral installation completing the sewer installer's test. Upon successful completion of the sewer installer's test and upon receipt of the fee as set forth in 921.74 (a), a license shall be issued. The sewer installer's license shall be renewed yearly upon receipt of an annual fee as specified in 921.74 (a). Failure to renew the sewer installer's license within a calendar year may be cause for retesting. The sewer installer's license may be revoked for failure to comply with this chapter and/or City specifications.
(b) Inspections. All materials shall be inspected and approved by the Inspector. After any sewer, drain or lateral or connection thereto has been constructed, but before it is covered or used, it shall be inspected and approved by the Inspector. Request for inspection shall be submitted twenty-four (24) hours in advance. Inspections shall not be made on Saturdays, Sundays or holidays.
(c) Inspection fee. There shall be an inspection fee charged for the services rendered by the Inspector as specified in 921.74(b).

All sanitary sewer manholes shall be either cast in place or precast concrete manholes conforming to A.S.T.M., C478 and the joints between sections shall conform to A.S.T.M. C443 and the City of Ashland's Standard details. All manholes shall be watertight structures with the top section being eccentric. Where a manhole is too shallow to permit the use of an eccentric cone section, a precast flat slab top shall be used. The construction of the flat slab top shall conform to the requirements of A.S.T.M. C478; equal alternate materials may be approved by the Engineer.
An inlet and outlet pipe shall be joined to the manhole with a gasketed, flexible, watertight connection as approved by the Engineer. The invert of the lowest pipe entering the manhole shall be at least three (3) inches (8cm) above the top of the base slab so that the sewer flow channel may be installed and shaped. The flow channel throughout the manhole shall be as shown on the standard City of Ashland drawings.
The pipe shall not extend beyond the inside face of the manhole wall. Concrete placed inside the manhole to form the channel through the manhole shall not be placed between the pipe and the opening so as to interfere in any way with the flexibility of the joint. The manhole frames and covers shall be Neenah R-1694 or approved equal for manholes to be located outside of pavement areas; all manhole covers in pavement areas shall be Neenah R-1676 or approved equal.

Spacing of manhole steps shall not exceed sixteen (16) inches (41 cm).
(3) Storm manholes, catch basins and cleanouts. All storm manholes and catch basins shall be cast in place, precast, solid brick or solid block with 1/2 inch (1.3 cm) thick portland cement plaster on all sides and shall conform to the City of Ashland Standard Specifications and standard drawings; "equal" alternate material may be approved by the Engineer. The pipe shall not extend beyond the inside face of the structure wall. Concrete placed inside the structure to form the channel through the structure shall not be placed between the pipe and the opening so as to interfere with the flexibility of the joint where flexible pipe is used. The top shall be set at the elevation shown on the plans. Manholes, catch basins and approved cleanouts shall be located at all changes of direction but at spacing of not greater than four hundred (400) feet (122 m).
Steps shall be provided in all manholes and catch basins which are more than five (5) feet (1.5 m) deep and spacing between steps shall not be greater then sixteen (16) inches (41 cm).
(4) Sanitary sewer lateral to be below basement floor. Whenever possible, the sanitary sewer lateral 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 public sewer, sanitary sewage carried by such drain shall be lifted by artificial means approved by the Inspector and discharged to the lateral.
(5) Size and grade. Each sewer shall be of sufficient size and uniform grade to accommodate the approved design flow to the satisfaction of the Engineer.
Sanitary sewer laterals shall not be less than four (4) inches (10 cm) in diameter. (Six (6) inches (15 cm) for multiple dwellings of three (3 or more units.) Four (4) inch (10 cm) sewer laterals shall have a minimum slope of one-eighth inch per foot (1/8"/ft) (1.2 cm/m) of length. In all cases, the lowest inlet to such sanitary sewer lateral, however, shall not be less than eighteen (18) inches (46 cm) above the top of the public sewer to which the lateral is connected.
(6) Alignment. All sewers shall be laid in as straight alignment as possible, and no sewer (except foundation tile) parallel to or within three (3) feet (.9 m) of any bearing wall which might thereby be weakened. Changes in direction shall be made only with properly curved pipe and fittings, and there shall be accessible cleanouts, as specified by the Inspector, at any change of direction of more then forty-five (45) degrees.
(7) Excavation. All excavations for sewers shall be open trench work, unless otherwise approved by the Inspector.
(8) Bedding. Class A bedding shall consist of a continuous concrete space cradle, installed at the location shown on the plans or as directed by the Engineer. Concrete shall conform to Item 499-Concrete. Class B bedding shall consist of a bed of approved granular material, passing a 3/4 inch (2 cm) sieve from four (4) inches (10 cm) below the bottom of the pipe and extending up around the pipe for a depth of not less than thirty (30) percent of its vertical outside diameter. The layer of bedding material under the pipe shall be shaped to fit the conduit for at least ten (10) percent of the vertical diameter of the conduit and shall have recesses shaped to receive the bell of the bell and spigot pipe.
Class C bedding shall consist of bedding the conduit in its natural foundation to a depth of not less than ten (10) percent of the total height. The bed shall be shaped to fit the conduit and shall have recesses shaped to receive the bell. All space within the width of the trench excavation shall be bedded with the same material, as specified. Unless otherwise noted on the permit, the bedding for sanitary sewers or any sewer under pavement shall be Class B. Except where otherwise directed by the Engineer for special conditions, the pipe shall be laid starting at the outlet end with the bell or groove end laid upgrade. The lower segment of the conduit shall be in contact with the shaped bedding throughout its full length. Suitable bell- holes shall be excavated for the bell of each bell end pipe so that the weight of the pipe will not be supported by the bells only. The pipe shall be fitted and matched so that when laid in the work, they shall form a conduit with a smooth and uniform invert. The first length of pipe laid shall be firmly anchored so as to prevent movement. All possible care shall be used when shoving the pipe together and all pipe ends shall be carefully cleaned before pipes are laid. Gaskets shall be installed in accordance with the manufacturer's recommendations. All no hub pipe shall be anchored by three (3) stakes per length.
(9) Backfilling. Backfilling shall cover the replacing of the excavated materials after the sewer and other structures have been built and the proper grading and shaping of the surface of the backfill. No backfill shall be placed over completed sewer and structures until they have been inspected and approved. Sewers shall be backfilled immediately after they have been inspected and approved.
All sewers shall be initially backfilled evenly on both sides of the pipe and to a minimum depth of one (1) foot (30 cm) above the pipe for the full width of the trench with the same material used for bedding placed in layers and tamped. In placing and tamping the initial backfill around the sewer, care shall be taken not to disturb the line and grade of the pipe. Stepping on or working over sewers shall be held to an absolute minimum until they have been covered with the initial backfill. In areas of existing or future pavement, the granular backfill shall be extended to the surface.
(10) Testing of new sanitary sewers. All new sanitary sewers shall be constructed in a watertight manner and shall be tested in accordance with the City of Ashland Standard Specifications. The inspector may waive the test on laterals if he is confident that it is unnecessary.
(Ord. 69-93. Passed 12-21-93.)
(11) Separate lateral required. A separate lateral and independent sanitary sewer lateral 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; then the lateral from the front building may be extended to the rear building and the whole considered as one lateral. In multiple dwellings of three (3) or more units, a minimum six (6) inch (15 cm) main lateral with a manhole or other suitable cleanout at the end and at intervals not exceeding four hundred (400) feet (122 m) shall be required. Each dwelling unit shall be tied into this main lateral with a four (4) inch (10 cm) line in a manner approved by the Inspector. Each of these lines shall be considered as a separate house lateral, and an inspection fee as required by this chapter shall be paid. All sanitary sewer laterals constructed after passage of the ordinance shall include a clean-out located just inside the right-of-way line. The clean-out shall comply with the City of Ashland Standard Drawings and Specifications.
(Ord. 51-01. Passed 6-5-01.)
(12) Connection to public sanitary sewer. The connection of the lateral into the public sanitary sewer shall be made at a manhole or "Y" branch, if it is available at a suitable location. If the public sewer is less than four (4) inches (10 cm) larger in diameter than the lateral and no properly located branch is available, a "Y" branch shall be installed in the public sewer at the property owner's expense at the location approved by the Inspector. Where the public sewer is at least four (4) inches (10 cm) larger in diameter than the lateral and no properly located "Y" branch is available, a neat hole may be cut into the public sewer and an approved saddle installed to receive the lateral, with entry angled toward the direction of flow. A smooth, neat joint shall be made, and the connection made secure and watertight by encasement in concrete, or as otherwise approved. The invert of the lateral at the point of connection shall be at an elevation of at least one-half (1/2) the pipe diameter of the public sewer above the invert of such public sewer.
(13) Connection to existing sanitary sewer lateral. Whenever a new connection is to be made to an already existing lateral, the person making the connection shall cause such lateral to be thoroughly cleaned. The existing lateral shall be inspected and approved by the Inspector before use.
(Ord. 69-93. Passed 12-21-93.)
(14) Liability. All costs and expenses incident to the installation, cleaning, maintenance and connection of any private sewer, drain or lateral shall be borne by the property owner. The property owner shall indemnify the City from any loss or damage that may directly or indirectly be occasioned by the installation of such sewer, drain or lateral. Blockages which can be cleared by standard sewer cleaning techniques and equipment are the responsibility of the owner. When the owner of a private sewer, drain or lateral determines that it is non-functional because of structurally damaged pipe or severely offset joints located in the City’s right of way, it is the owner’s responsibility to demonstrate to the City that all or part of the problem is located in the City’s right of way. When such a problem is confirmed, the City will repair or replace the problem pipe section in right of way and install a clean-out normally just inside the right-of-way line. The City will be responsible for all aspects of the rehabilitation project including restoration of the construction area. Since frequent and/or major blockage of a pipe is an indication of poor joints and/or collapsed sections, and that the pipe is a probable source of clean water infiltration into the public sanitary sewer system, if appropriate, the City may direct the owner to rehabilitate or replace sections of the private sewer, drain or lateral at the owner’s expense.
(Ord. 51-01. Passed 6-5-01.)
(15) Supplementary specifications. The standard construction specifications and street opening specifications of the City shall supplement this Chapter and shall apply to all materials and workmanship.
(16) Lawn grading. All lawn grading shall be performed and maintained in such a way as to prevent surface water from entering the foundation tile or sanitary sewer system. (Ord. 69-93. Passed 12-21-93.)
