Septic Tank Pumps
Biological wastewater treatment systems such as SBR (sequence batch reactor) and Fixed-bed (reactor) Wastewater Treatment are the norm for decentralised remote wastewater treatment. While modern biological wastewater treatment systems operate with a combination of sedimentation stages and oxygen-input to achieve the highest treatment levels, septic tanks operate only by means of staged sedimentation.
The treated wastewater within the final chamber, also referred to as effluent, is in a functioning treatment system or septic tank free from solids and discolouration with saturated raw sewage elements.
This relatively clear effluent can then be discharged towards the percolation area, where the natural infiltration within an underground gravel-bed as well as lower lying soil- & ground-layers further cleanse the effluent water before it reaches the groundwater reservoir.
Every private dwelling and commercial building not connected to the municipal sewerage network is obliged to adequately treat raw sewage and wastewater in a decentralised remote wastewater treatment system or septic tank.
Why is a submersible pump necessary within a septic tank or wastewater treatment system?
Unless the site landscaping conditions allow the final chamber to naturally overflow towards the percolation area or subsoil polishing-filter, a submersible wastewater pump is required to discharge the treated effluent. Reoccurring level-controlled discharge of the final chamber ensures the wastewater treatment system or septic tank can operate without any backlog or overflowing.
Pumps for septic tanks / treatment systems with Float Switch
Most submersible sump pumps installed in a septic tank or wastewater treatment system are equipped with a float switch, which allows the pump to switch ON/OFF fully automatically according to the level within the final effluent chamber.
Pumps for septic tanks / treatment systems without Float Switch
Some wastewater treatment systems could be equipped with a control panel, which switches the pump directly (not common in Ireland or Northern Ireland). In these cases, a pump without a float-switch is required.
Usually, an external device (float switch or similar) is connected to the panel, which then prompts the panel to switch the submersible pump level-controlled. The advantage of such a setup is that the panel could also monitor operational-hours and switching-cycles of the pump.
As the majority of wastewater treatment systems and septic tanks are located at private domestic facilities and small commercial locations, most submersible wastewater pumps used at these installations are in single-phase (230V/50Hz). Some commercial systems with greater volume demand may however be equipped with submersible pumps in three-phase (400V/50Hz).
In the event of a septic tank pump replacement, check the technical details of your existing pump to identify a suitable alternative below. If you require assistance in identifying the correct submersible pump for your treatment system, please contact us.

It is used in sump pump chambers for applications such as general drainage as well as wastewater & sewage water handling with a solids passage of up to 10mm. With a maximum volume capacity of 260 litres per minute and a maximum pumping head of 13.1 metres, the EBARA BEST 2 MA is used in commercial and agricultural installations, where higher pumping volume is required, and in private domestic installations with prolonged pumping distances. Applications include draining wells, garages, cellars or places subject to flooding. Wastewater Treatment System & Septic Tank Pump The EBARA BEST 2 MA is used to pump treated effluent in domestic treatment sytems and septic tanks where the subsoil polishing filter area or percolation area are not located in close proximity to the final effluent chamber. The higher performance and pumping height of the pump compensates the pressure loss involved with longer pipe distances and ensures the final effluent chamber is sufficiently emptied during pumping intervals. Regular maintenance of your wastewater treatment system or septic tank & good practice ensure sufficient treatment levels in the final effluent chamber. This is also important in order to achieve a satisfactory lifespan of the submersible pump.

A wastewater treatment system as well as a septic tank requires a functional & reliable effluent pump in the final chamber in order to continue to operate. Replacing the septic tank pump is therefore usually an urgent matter, as system backlog and potential overflowing with contamination to the surrounding ground area should be avoided. Regular maintenance of your wastewater treatment system or septic tank & good practice ensure sufficient treatment levels in the final effluent chamber. This is also important in order to achieve a satisfactory lifespan of the submersible pump. A general guideline to wastewater treatment systems & servicing, including replacement of the submersible effluent pump, is available for download in pdf-Format: GUIDE – Wastewater Treatment Systems Non-return flap valve - included as standard The non-return flap valve can be easily included to the pump discharge when fitting the pipe coupler. The non-return flap valve prevents water within the pipe from re-entering the pump and sump chamber after the pumping cycle has ended. This can significantly reduce the number of pump starts, especially in smaller sump chambers with less volume.The non-return flap valve should not be included, if the discharge pipe is located in an environment subject to frost or sub-zero freezing temperatures.
