In a building in which the whole or part of the plumbing system lies below the house connection to the public sewer the outlet from said plumbing system or part thereof shall discharge into a sump or receiving tank from which the sewage shall be pumped through a pipe to the house connection or to the public sewer.
The said sump or receiving tank shall be adequate in capacity. It should be discharged not less frequently than once each hour. It shall be constructed in a water-tight and substantial manner of masonry, vitrified clay, or metal. It shall be provided with an air-tight cover. Any pipe discharging into the sump or receiving tank shall not be submerged.
No storm, surface or ground water shall be conducted to a sump or tank receiving domestic sewage. Such water may be conducted to a separate sump for the purpose of pumping it to the surface of the ground or to a storm sewer if such exists. (Ord. 304, 3-6-66)
In the event that only the floor drain in a building is involved at property where the sanitary sewer was not constructed deep enough to serve the floor drain, then the floor drain, alone, may be omitted from connection with the public sanitary sewer, instead of complying with the requirements for sump construction. In this case, adequate provision shall otherwise be made. (Ord. 334, 1-2-69)
