The 1.2-megalitre North Kilkerran tank on the Yorke Peninsula in South Australia has achieved immediate operational improvements after being fitted with a solar-powered mixing device.
By reducing temperature layering and enabling even dispersal of disinfectant levels, the mixing device has improved water quality for around 430 SA Water customers, while ensuring more stable supply for homes, businesses and farms across the region’s 50km of water mains.
The device, which was installed in June, uses solar energy to power a submersible impeller that constantly circulates safe, clean drinking water, maintaining even temperatures and preventing nitrification – a build-up of bacteria.
“Our teams are always looking for smarter, more proactive ways to deliver better service for our customers,” SA Water’s Kadina Field Operations district leader Shane Whelan said.
“Being the first to install and operate this technology is a real credit to our people’s initiative and problem-solving skills, and we’re already seeing the benefits in water quality outcomes.”
The device has removed the need for tank flushing and mixing to be carried out manually each month, freeing up crews to focus on other maintenance tasks.
SA Water’s senior manager – field operations Matt Minagall called the device a “game-changing” addition to regional water management.
“It’s safe, sustainable and efficient, and supports our people in the field by reducing manual workloads while still maintaining quality drinking water for our customers,” he said.
“Importantly, it also means fewer site visits and less disruption, particularly during high-demand periods.”
