We're continuing to work closely with our communities and stakeholders to deliver a reliable water supply and support future growth in the region.
Our plans to secure drinking water supplies
A $10.8 million project to construct 10.7 kilometres of new underground water supply main from a pipeline at Edward Road pump station to the Chapman Valley Road in Geraldton is nearing completion. This work will improve the water supply to the northern region of Geraldton from the Allanooka water supply main.
We have expanded groundwater sources that supply Exmouth and equipped the Southern borefield with solar energy. This has increased the capacity of the borefield to produce an additional 500,000 litres of water each day.
Work to replace 24.3 kilometres of water supply bore main, which services the town of Carnarvon as well as the local growers was completed. Alternative options for ensuring the continuity of critical power supply to the Carnarvon borefield is currently underway to compliment this work. These projects aim to improve the reliability of water supply for the town.
Plans are in place to construct treatment plants in Mt Magnet, Sandstone, Cue and Meekatharra. The new water treatment plants will reduce the naturally high levels of salinity and nitrates in the water and improve scaling and hardness.
Improving our wastewater services
Upgrades of infiltration ponds at one of Geraldton’s wastewater treatment plants were completed to increase reliable plant operation and provide recycling opportunities. The chlorination system and treatment ponds in Carnarvon were upgraded to allow Water Corporation to continue to support recycling of wastewater in town. The project has doubled the capacity of the reuse scheme from 600kL/day to 1.2ML/day.
Reducing water use
We are working with communities in Jurien Bay and Geraldton to change water use behaviours through our Waterwise Program delivered to stakeholders, schools and local government associations. This includes retrofitting inefficient appliances for residential and non-residential customers, and leak repairs.
A tailored project underway in Cue to reduce overall consumption by 10% over 2 years to extend scheme capacity and contribute to a deferral of new source development.
Increasing water recycling
Approximately 32% of all treated wastewater in the Mid West region is recycled. All of the treated wastewater from the Exmouth, Carnarvon, Kalbarri and Dongara is supplied to parks, gardens and ovals.
Further opportunities for increasing re-use of treated wastewater exist in the Narngulu area. Investment in conveyancing infrastructure and demand from industry is vital to progress these opportunities.
