Rules and regulations governing the size, slope, alignment, and materials of construction of a sewer and the method used in excavating, placing of the pipe, jointing, testing, and backfilling the trench shall include, but not be limited to the following:
(A) Connections with sewers must be made at the branches and with the slant already put in by the city, if any.
(B) Any new connections made shall be made by properly placing a wye branch in the line of the sewer.
(C) All connection pipes must be laid in true line from the sewer. All connection pipes must be laid in true line from the sewer to the curb in an open trench and before any filling is done.
(D) All connection pipes must be enveloped with earth or sand to a thickness of four inches.
(E) All joints of sewer pipe must be made with Portland Cement Mortar or its equivalent in the best manner and to the satisfaction of the engineer or such employee as designated by the city.
(F) After the pipe is properly laid, the refilling must proceed at once, and it must be thoroughly tamped or puddled or both and so done that there shall be no surplus earth left.
(G) Should there be a deficiency of earth to fill the excavation, then the person doing such work must supply such deficiency.
(H) No rock of any sort larger than four inches in any direction shall be put into any excavation.
(I) Changes in direction of waste or sewer pipes shall be made with curved pipes and wye branches, and connections shall be made with wye branches and sanitary tees. Cleanouts are to be placed in soil or waste pipes just inside of the wall where the house drain enters the basement. Cleanouts shall be of the same size as the drain pipe in which they are installed.
(J) Sanitary sewer drains from any building shall be connected with an approved pipe at least four inches in diameter as designated by the Public Works Superintendent, laid in a uniformly ascending slope of at least one-fourth inch per foot from the sewer towards the building. All connections from the sewer pipe and from the curb line to the building are to be of PVC pipe.
(K) At least 24-hours notice must be given to the Public Works Superintendent or other officer designated as Sewer Inspector by any person who is to make a connection with any sewer or drain when such work will be ready for inspection, previous to making said connection.
