Greywater Holding Tank Cleaning

Greywater sullage holding tanks catch wastewater (greywater) which exits your shower, bath, laundry sink and washing machine. Greywater holding tank units are installed at premises which are not connected to council sewerage. These units consist of the tank with a submersible pump partially elevated toward the bottom which pumps out the cleaner water, while retaining the silt and dirt particles (called sludge). The water which exits the greywater sullage holding tank will either travel to a sprinkler system or to a greywater purple sullage hose where it is watered onto the lawn/paddock. Premises which do not have a greywater holding tank will usually have their greywater diverted to underground dispersion pipes called “absorption/aspiration trenches / drain fields”.

As the sludge accumulates at the bottom of the greywater sullage holding tank, it will eventually submerge the pump in sludge, causing hose blockages, pump breakdown or burnout. Also, the more accumulated sludge in the tank, the greater smell the greywater holding tank will emanate. To lengthen the submersible pump life and reduce odours, council recommends pumping out greywater holding tanks every 6 to 12 months.

Protect Your Pump

Sludge, hair and debris accumulate in the bottom of the tank which can cause the pump to breakdown or burnout.

6-12 Months

Councils recommend 6-12 monthly pump out of greywater holding tanks.
