§ 3.817. Sewage effluent pumping equipment for on-site sewage disposal systems.

(a)

Pump and Pit. Where necessary to lift the septic tank effluent to the disposal area, an approved pump and pump pit shall be provided.

(b)

Pit Design. The pit shall be specifically designed for sewage effluent and shall be of sufficient capacity to accommodate the particular application. The pump pit shall be located after the septic tank and only septic tank effluent shall enter the pump pit unless otherwise authorized by the approving authority.

(c)

Sump. The sump containing the pump shall be watertight, accessible from grade with a 20-inch minimum manhole, and structurally sufficient for the existing or proposed use. Concrete components shall have their only construction seam located above the inlet to the sump.

(d)

Alarm. An audible or visual high water alarm shall be installed in the building per manufacturer's specifications. The high water alarm shall be on a separate electrical circuit from the pump.

(e)

Minimum Emergency Capacity. Unless otherwise specified by the approving authority, a minimum emergency capacity equal to the design flow shall be provided, the capacity to be measured between the invert of the inlet to the pit and the elevation at which the high water alarm is activated.

(f)

Force Main Pipe. The force main pipe between the pump and point of discharge shall be SCH 40 or SDR 21 PVC or approved equal. All SCH 40 and SDR 21 fittings in this line shall be pressure rated. Force mains shall be installed so as to prevent freezing and no shallower than 36 inches below grade.

(g)

Electrical Connections. All electrical connections to the pump and float switches shall be located outside the pump chamber and protected from the weather.

(h)

Pump Pits Serving Nonresidential Uses. All pump pits serving nonresidential uses must have duplex pumping equipment.
