Councils participating in the Waterwise Councils program are required to regularly undertake water efficiency audits. We have undertaken Water Efficiency Audits for a number of Waterwise Councils (Joondalup, Kwinana, Cottesloe, Canning, Mandurah, Caimbridge and Melville) involving facilities such as: aquatic centres, operations depots, toilet blocks, kitchens, function and entertainment centres, administration buildings and recreation centres. We have also assisted in the development of Water Efficiency Action Plans and Waterwise Aquatic Centre Management Plans for councils.
We undertake household inspections to identify opportunities to reduce water use, including investigation of unexpectedly high water use.
