Effluent system upgraded
Unusually for towns in Australia, Karratha has always recycled its waste water for use on green areas around the city.
However, our effluent reuse system was ageing and becoming costly to maintain — and it needed to be extended to incorporate the new suburbs to the west of town.
Through the Royalties for Regions program, some $113 million has been spent to upgrade and extend our sewage treatment and effluent reuse systems.
You will have seen the excavation works around town for the last couple of years.
Some 18km of new pipeline were installed, half of which was to replace and extend our current recycled water system.
Work also involved new pump stations at Cattrall Park, Millars Well Oval, Tambrey Oval, Brolga Park and in the city centre.
Our local wastewater processing plant has been upgraded to treat up to 10 million litres of wastewater a day and the recycling facility now has the capacity to produce up to 6 million litres of highquality recycled water each day.
The effluent reuse scheme incorporates the introduction of intelligent irrigation technology which is able to respond to tank water levels and irrigate spaces on a priority basis, so parks and ovals that require regular irrigation still receive water when supply levels are low.
While some people may shudder at the thought of what was once sewage being sprayed on our parks and gardens, be assured the water is now treated to class A1 standard.
This is a world-class project, providing great environmental outcomes for our city.
