Pool Water Conservation

Recent shortages of potable water supplies throughout Australia has prompted consideration of ways large pools can be designed to minimise water consumption. Most attention has focused on minimising water used to backwash filters. However in our experience reporting on the condition of large pools, pool water loss from leaking pool shells and broken pool water circulation pipes is considerably more than the water used to backwash sand filters. Chemically treated and often heated pool water can also be lost in large quantities, through the overflows of balance tanks in poorly designed and poorly operated pools. Few pools have water meters correctly positioned to quantify such water losses. Loss of water through both leaks in the pool shell and pool pipework can be minimised and possibly eliminated by having a pool designed by an experienced pool engineer.
