Case study 1: Canterbury Dialysis Unit
When the Canterbury dialysis unit updated its water purification system with the installation of a new reverse osmosis plant in 1997, it was soon apparent that large volumes of reject water were being ‘lost to drain’. Within two years, and with the help of the hospital’s Estates Department, a simple system capable of recycling 800 litres of this water per hour was installed at a cost of £15,000. The system has now been running for over ten years, saving the Trust £7,500 each year on mains water and sewerage costs.

The salvaged reject water is directed to a recovery tank in the basement. From there it is pumped up to the grey water tank on the roof, which then supplies the water to the hospital toilets. Float switches divert reject water to the drain if the grey water tank becomes full, and diverter valves direct the reject water directly to the drain from the reverse osmosis system during monthly chemical disinfections.
