A RECENT groundwater filtration system upgrade at Ozone Reserve is set to save the City of Perth $1.7 million over 15 years.
The new filtration system can filter up to 500,000kL of groundwater annually, providing irrigation to parks across the CBD.
City of Perth Chair of Commissioners Eric Lumsden said the system now had a “state-of-the-art non-chemical process”.
“This new system will see the maintenance costs of groundwater filtration drop by almost 90 per cent per annum, with the replacement cost of the system expected to be recouped within five years,” he said.
Mr Lumsden said safety outcomes will also improve for workers because it no longer uses chemicals.
“We will also see reduced maintenance costs of City assets, as the upgraded filtration process minimises iron levels in the irrigated water, and significantly reduces staining,” he said.
