A Goulds septic tank pump is a key component of the septic system, a small-scale sewage treatment system common in areas with no connection to main sewage pipes provided by local governments or private corporations. Other components, typically required by local governments are check valves, ball valves and high alarms. In the USA approximately 25% of the population relies on septic tanks. In Europe, they are in general limited to rural areas only. Since a septic system requires a drainfield that uses a lot of land area, they are not suitable for densely built cities. Periodic maintenance is required to remove solids that settle and eventually fill the tank.
Liberty Pumps are used to move effluent out of a septic tank pumping chamber to a drainfield. Septic effluent pumps are used in raised bed, mound, or sand-bed filtration septic systems in which the absorption bed is located higher than the septic tank. In these installations septic effluent is pumped from a final chamber in the septic tank or from a second effluent chamber up to the absorption system. Septic tank effluent pumps are built to higher standards of durability and for more demanding service than a typical sump pumps. The septic tank effluent pump does not have to handle solid, but many solids are flushed down the toilet by mistake or negligence and a solid handling pump then becomes a plus.
Zoeller Pumps are an excellent choice when a pump is required to pump the effluent from the septic tank to the absorption area. The Zoeller Septic Tank Pump is located in a pump tank or dosing tank following the septic tank(s) and before the absorption area. There usually is also an high water alarm box located in the house (usually the basement or garage) that sounds when there is a high water level problem. Typically there is a reserve in the pump tank to enable water use in the house when the alarm sounds, but the issue needs to be addressed ASAP.
