Treatment Ponds desludging works
Further improvement works are getting underway at the South Boulder Wastewater Treatment Plant, including scheduled desludging activities on one of the plant’s primary treatment ponds from early May.
Wastewater to Reuse
The City is the sole owner and operator of recycled water services to Kalgoorlie-Boulder and is the largest operator in Western Australia of its kind, outside of the Water Corporation.
Current wastewater services involves the collection of sewage through an underground pipe network across the City. The network connects to the City’s South boulder Wastewater Treatment Plant where the waste is processed.
Utilising primary and secondary treatments, the City is able to beneficially re-use treated water by irrigating parks and gardens and supplying water to local users.
The City is committed to ensuring the fair and equitable distribution of recycled water for the benefit of the entire community.
Why we use recycled water
The City uses recycled water to help maintain parks, sporting grounds and public spaces while reducing demand on drinking water supplies.
Using recycled water helps:
- Preserve drinking water supplies
- Support green public spaces such as parks, gardens and sporting ovals
- It's provided to a range of local recycled water uses such as schools
- Improve long-term sustainability
- Reduce environmental impacts
- Support local industry
The City’s recycled water system is one of the largest operated by a local government in WA.
South-Boulder Wastewater Treatment Plant
The South Boulder Wastewater Treatment Plant plays a critical role in treating wastewater and supporting the City’s recycled water network.
What the Plant Does
The facility:
- Receives wastewater from across Kalgoorlie-Boulder
- Treats wastewater through multiple processes
- Produces recycled water for reuse
- Supports public open spaces and industry
Approximately 6.8 million litres of wastewater moves through the facility each day.
How recycled water works
Every day, wastewater from homes and businesses across Kalgoorlie-Boulder is collected through our sewer network and sent to the South Boulder Wastewater Treatment Plant (SBWWTP).
Here's the whole process:
