A NEW spring waterwise offer to help save 155 million litres of valuable water is now available, with rainfall run-off into Perth's dams remaining significantly below average despite the wet weather.

Over winter, metropolitan dams received less than one third of the rainfall run-off than the long term (post-1975) average, leaving metro dams holding 38 billion litres (GL) less than this time last year (308GL vs. 346GL).

With more than 30 per cent of household water used to water gardens and lawns, Perth and Peel residents are being encouraged to get their reticulation in peak condition ahead of summer.

To help save valuable water and reduce bills, Water Corporation, in partnership with Irrigation Australia WA, has launched a new Waterwise Irrigation Rebate (WIR) to Perth and Peel residents, providing up to $200 off eligible waterwise irrigation products or services.

These include having an existing system serviced or improved by a waterwise irrigator or waterwise irrigation design shop to fix leaks and improve water efficiency or the purchase and set up of a weather-based irrigation controller, which uses weather data to adjust sprinklers to prevent overwatering.

Last year, Water Corporation funded around 2000 irrigation checks and almost 1600 rebates for weather-based irrigation controllers.

Around half of the systems inspected had a leak, while one quarter had either incorrect irrigation run times or watering times.

Collectively, these waterwise offers contributed to saving an estimated 286 million litres of valuable drinking water - equivalent to nearly 114 Olympic-sized swimming pools.

The WIR is a limited offer available until May 31, 2025 or until allocation is exhausted.
