The tank needs to be large enough to deliver the flow necessary to supply the system and provide enough storage space in timed systems to hold the flow from the house until the time of pumping or to provide some emergency storage in on-demand systems in the event of a pump failure. A timer controls the pumping of doses in a timed system but also has a high-level alarm. The pump is controlled by a set of floats with a third separate alarm float to warn if the water level in the tank rises too high, indicating a pump problem. Dose amounts in this case are generally about one-quarter of the estimated daily sewage flow from the residence. If there is an on-demand system the pump is turned on when enough effluent collects in the tank and shut off after the dose is delivered. The dosing tank is located after the septic tank or other sewage tank and before the lateral system for effluent distribution. Get Septic Tanks articles, news and videos right in your inbox!
