Pump Station

Most septic systems work off of gravity. Each component of the system is slightly lower than the preceding component. This allows the even movement of waste material and liquids without the need for mechanical devices. When this type of system is not possible, due to ledge or a high water table, a pump station must be installed to pump the effluent up to the raised leachfield. This is called a raised septic system.

The pumping unit is electric and will be a fully submersible unit. While designed to handle liquids, the pump will also handle small amounts of sludge and sediment which may occasionally find its way into the pump chamber. The septic tank should be cleaned out regularly to avoid large amounts of sludge entering the pump chamber and clogging the pump. It is also very important that you do not flush bulky items. They can get stuck in the pump which can cause the pump to fail. When the alarm goes off call a professional immediately.

Just like a car the pump has a motor that can have problems or fail. We also recommend the pump chamber get a “check-up” when you have the tank pumped. The “check-up” includes testing the alarm and floats to make sure they are in good working order. Vibrations from the pump turning on and off can cause them to become disconnected and eventually fail. The pump is also cycled so the technician can hear and see that it is working properly. Sometimes the pump chamber needs to be cleaned if the sludge or sediment content is high.
