Harlequin 1100 Litre Effluent Pump Station – Single Pump
The Harlequin 1100 Litre Effluent Pump Station is designed for pumping treated final-stage effluent from a sewage treatment plant or septic tank to a suitable drainage field. It can also be used to pump treated effluent from a sewage treatment plant to a watercourse, subject to the relevant Environment Agency permits and requirements.
Manufactured from durable rotationally moulded polyethylene, the Harlequin pump chamber provides a strong and lightweight solution that is easier to handle and install than many GRP alternatives.
The 1100 Litre pump station is supplied with a single pump as standard. Twin-pump options are also available for installations where additional reliability and the reassurance of a backup pump are required.
With an 1100-litre capacity, the pump chamber provides up to 24 hours of storage for domestic installations serving up to 7 people, making it a practical solution for larger households and properties requiring reliable effluent management.
