A waterfall of savings in Willoughby
Installation of a new water filtration system at the Willoughby Leisure Centre in Sydney’s north has saved more than $14,000 and one million litres of water, according to Willoughby City Council. Keen to focus on sustainability and efficiency, the council engaged engineering and water treatment experts Roejen Services in late 2017.
The existing system lost large volumes of heated and treated water through backwash, so Roejen installed a system utilising OC-1 filtration media, which has generated improvements and savings across the board, according to Mayor Gail Giles-Gidney.
“It’s made savings in water, chemicals, heat loss and electricity, not to mention less downtime so it’s now a better experience for Leisure Centre patrons.
“The new system uses settlement, rather than the traditional entrapment method, to more efficiently remove microparticles from water, keeping the heated spa and pool clean and fresh for users,” Giles-Gidney said.
Water quality has improved through a 25% increase in turnover of the pool water — or about 18 extra turnovers each day.
“With the reduced downtime we were able to provide a better experience for patrons at a lower running cost, which equated to an excellent result from the project,” Giles-Gidney said.
Using the new system allowed pump speeds to be reduced from 50 to 42 Hz, saving 70,000 kilowatt hours/per annum or about $14,000 a year.
Willoughby Leisure Centre says it is the first to install this system in Australia. The project was funded by council’s environment levy.
