Whenever possible, the side sewer shall be brought to the building at an elevation below the basement floor. No side sewer shall be laid under any building or within two and one-half feet of any foundation wall unless the side sewer is constructed of cast iron pipe. The minimum depth of trench shall be two feet. The side sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe fittings, as approved by the water and sewer superintendent. Fittings shall be used at all major changes of direction and a clean-out shall be provided at such fittings.
Whenever a side sewer or drain for a single-family residence cannot be constructed low enough to permit gravity flow to the public sewer, sanitary sewer service may be authorized to allow sewage carried by such drain to be lifted by approved artificial means and discharged to the public sewer; provided, however, that the cost of installation, operation, maintenance, inspection, and repair/replacement of the approved artificial sewer lifting facilities and appurtenances shall be at the property owner's sole expense. In addition, a city of Snoqualmie single-family resident sanitary sewer pump system agreement in a form approved by the public works director shall be executed by the property owner and recorded against the property to be served by artificial sewer lifting means, prior to installation of any artificial sewer lifting facilities or appurtenances or connection of said facilities or appurtenances to the city's sanitary sewer system.
