Kaltjiti sports solar-powered desalination plant

Kaltjiti's new desalination plant is capable of producing up to 120,000 litres of water each day

A new solar-powered desalination plant is now up and running at Kaltjiti in the state’s Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, as part of SA Water’s continued efforts to deliver safe and reliable drinking water to local communities. 

The small-scale reverse osmosis plant can produce up to 120,000 litres of water each day. It will deliver high-quality drinking water to the remote Aboriginal community. 

SA Water’s General Manager of Operations Chris Young said the improved facility replaces Kaltjiti’s existing water treatment plant. 

“Having worked closely with communities across the APY Lands for many years, we understand the important role that a sustainable water source plays in maintaining public health and hydration. It will also facilitate future growth and development,” Young said. 

“Using the process of reverse osmosis, the plant removes any naturally-occurring impurities like high levels of salinity. High salinity levels are found in many of Australia’s inland groundwater sources. The plant will manage levels of naturally-occurring fluoride in line with the Australian Drinking Water Guidelines (2011) before delivering high-quality drinking water to the community. 

Solar-powered desalination plant vital for remote communities

“Like many of our remote treatment sites, the plant is also fitted with a high-tech computer system. It can be remotely monitored and controlled by our people. Any faults or maintenance can be identified early and repaired as needed by our team or local contractors. 

“In our path to becoming proactive environmental leaders, the plant is also fitted with 38 kilowatts of solar panels and additional battery storage, helping to harness the region’s traditionally warm and sunny weather to reduce carbon emissions and our reliance on power from the local grid.” 

“With the existing plant reaching the end of its useful life, Kaltjiti’s new desalination plant will help us to continue providing sustainable water services to the local community well into the future.” 

SA Water manages water supplies and/or wastewater disposal systems in 13 Aboriginal communities and government facilities in the APY Lands. They include Indulkana, Mimili, Kaltjiti (Fregon), Umuwa, Pukatja (Ernabella), Yunyarinyi (Kenmore Park), Amata, Pipalyatjara, Kalka, Kanpi, Nyapari, Murputja and Watinuma. 

Included in these operations are 62 bores (15 solar-powered), five desalination plants and one wastewater treatment plant.
