Direct Drainage Reviews

The Harlequin 1100L Sewage Pump Station is suitable for pumping sewage from a property to either a mains sewer connection, sewage treatment plant or septic tank. This chamber can also be used for pumping final stage effluent from a sewage treatment plant to a watercourse (subject to obtaining EA permits).

 Harlequin pump chambers are manufactured from rotationally molded polyethene making them stronger and easier to handle than some of the GRP alternatives.

 There is a twin pump version of this pump station.

     When do you need a pump station?

    • When the cost of groundworks to allow sewage to flow by gravity outweighs the cost of a sewage pumping station.

    • When the sewer line passes over a ridge.

    • If basement floors are too low to allow sewage flow by gravity.

    • Where gravity system has not been built.

    What is a sewage pumping station and how does it work?

    A pumping station is made up of a large tank, known as a wet well, that acts as the receiver for sewage from a building or a group of buildings. Sewage from individual houses flows into the wet well.

    The sewage will then sit in the well until it reaches a predetermined level. Once it reaches this level, a pump will kick in to pressurise the sewage so that it will travel out of the wet well, uphill, to a point where it enters the main sewer, or that it can then travel into the main sewer using gravity.

     Advantages of a Sewage Pump Station

    • A pump station offers convenience when installing a sewage system, and has the potential of cutting construction costs.
    • Pump stations are fitted with remote monitoring systems, which keep operators updated.
    • Sewage is pumped automatically without any human contact, which eliminates the risk of health problems.
    • Different sizes of pumps are available for domestic applications and commercial applications.
    • The intake of the pumps is often wide to prevent blocking.
    • Sewage pumping systems are fitted with alarms to alert you to problems with the system. This minimises the risk of sewage overflowing as you are alerted quickly.

    What is a Grinder Pump?

    Waste from water-using household appliances (toilets, bathrooms, washing machines etc.) flows through the home’s pipes into the grinder pump’s holding tank. Once the wastewater inside the tank reaches a specific level, the pump will turn on, grind the waste into a fine slurry, and pump it on to its next destination.
