Services

Lancelin South Water provides non-potable water, potable water and sewerage services. Our aim is to provide high quality service to residents and tenants of the Lancelin South Development.

Bore Water

Bore Water, abstracted from a production bore screened within the Leederville aquifer, is the source for the potable and non-potable water supplied to Lancelin South. The bore is located within natural bushland approximately 1 km to the east of the development.

The production and associated monitoring bores are regularly checked for water quality and water level, to ensure we meet the requirements of the Department of Water and Environmental Regulation (DWER) and the Department of Health (DOH).

Non – Potable Water

Bore Water is pumped to the water treatment plant, located within a secured fenced compound. The bore water is treated to remove dissolved iron and filtered to remove sediment. This water is not suitable for human consumption but is cheaper to use for watering lawns and gardens, washing cars or general garden clean-up.

Potable Water

Some of the non-potable water is further treated using granular activated carbon filtration, reverse osmosis desalination and finally disinfected with addition of sodium hypochlorite solution (chlorination). The treated potable water is stored in a tank at the treatment plant for customers to use.

Chlorination is the most commonly used form of drinking water disinfection and has been used for more than 100 years to protect practically all Australian water supplies, including Perth.

The potable water produced by Lancelin South Water is regularly tested by a NATA accredited laboratory to ensure it meets the requirements of the Department of Health and the Australian Drinking Water Guidelines (ADWG).

Sewerage

Sewerage from the Lancelin South Development is collected and transferred to a small treatment plant, located outside of the residential area. The sewerage is treated by a biological process followed by chlorination before it is finally discharged to an infiltration pond.

The sewerage treatment process is monitored regularly to ensure it meets the requirements of the Department of Health and the Department of Water and Environmental Regulation.
