The geothermal bore to heat the pools and pool hall was fully functional after a six-week testing period, while the grey water recycling system went online last month.

City of Canning chief executive Lyn Russell said tests on the geothermal bore showed outstanding results.

‘Tests show that the heating is more reliable than the gas heating system,’ Ms Russell said.

In the heating process, water is extracted from 1.1km underground at 48C and pumped into an exchange unit, transferring the heat to the pool water.

The underground water is then pumped back into the ground at a depth of 500m.

Despite cold conditions outside during testing, the pool water temperature remained constant, with a variation of just 0.10C.

‘This is a closed system and there is very little loss of water to the underground system,’ Ms Russell said.

The grey water recycling system uses filtered and treated waste water from showers to flush the toilets and reticulate garden beds, resulting in significant water savings.
