23 ECO ENTERPRISE Excavating a massive pit beside Sydney's famous Bondi Beach in order to build and bury a 300,000-litre concrete storage tank was a challenging task for Waverley Council two years ago. Today, however, the tank is the mainstay of a sustainability initiative that each year harvests, treats and re-uses 50 million litres of stormwater that was previously discharged, untreated, into the ocean. That translates into saving 50 million litres of potable water, which in the past had been used for ir rigation and cleaning and ablution purposes around Bondi. The new project also reduces stor mwater pollution at the beach itself, while remaining underground to maintain public space. Completed early last year, the project is part of Waverley Council's Environmental STORMWATER SOLUTION SUSTAINS BONDI BEACH Neatly concealed beneath a lush green lawn, Bondi's new stormwater initiative not only saves 50 million litres of drinking water a year, it also cuts pollution from entering those iconic waves that lap its shore.

Considering Bondi Park and Bondi Pavilion used 59 per cent of the council's mains-water in 2011--12, the new stormwater har vesting facility is a signifcant milestone on that roadmap. Council has also made the installation carbon neutral by powering the treatment plant with a 10kW solar system mounted on the roof of Bondi Pavilion.
