Save Water Pool

Swimming pools need not be wasteful!

  • Choose a Smart WaterMark approved pool cover to become more efficient with your water and energy.
  • Reduce the amount of backwashing you do to save water and maintain the effectiveness of your pool filters.
  • Monitor the temperature you set for your pool - turn the heat down during the warmer months
  • Use a timer on your pool that can also be programmed to run at different times during different times of year

Always use a pool cover

Pool covers reduce evaporation.

Pool covers reduce expensive chemical and salt evaporation.

A good pool cover conserves water temperature and as a result save on energy bills and greenhouse gas.

Covers help reduce algae growth which in turn means less scrubbing and chemicals.

You can even increase your pools temperature without increasing energy costs.

Save time and energy cleaning the pool. Covers keep water cleaner as they serve as a barrier to debris, leaves and yard litter.

Smart pools

Look for the Smart Approved WaterMark logo on a product website or packaging so you know that the product you are buying is water efficient, durable, fit for purpose and environmentally sustainable. Products endorsed by the Smart Approved WaterMark have been reviewed by a credible, robust Independent Expert Panel.

Reducing evaporation

Pool covers
A pool cover is the most effective way to reduce evaporation. A good pool cover, if properly used, will reduce water evaporation from your pool and also reduce your pool chemical and salt bill. Pool covers range from simple leaf covers (which reduce evaporation by around 40%) though to thicker blankets and security covers (which can save up to 90% evaporation). Smart Approved WaterMark certifies a range of good quality pool covers.

Pool blankets
These offer a more affordable option and are available in bubble plastic or foam, which float on the water's surface. If used with a roller they can be easily removed before pool use, then spread again after you have finished swimming for the day.

Liquid pool covers
These are a new alternative available if you don't want to hide your pool water with a cover or blanket. The chemical forms a barrier on the water's surface which inhibits evaporation by up to 40%. It can either be added to the pool daily by hand or by using an automatic metering system.

Increase shade
Covering your pool with a shade will further reduce evaporation as well as protect swimmers from harsh sun rays. Use shade cloth or a shade sail.

Prevent wind exposure
Wind contributes to evaporation. To increase water efficiency, adjust the landscape around your pool with walls and hedges that create shelter from the wind.

Capture rainfall to refill your pool

Installing a rainwater tank is a great way to reduce the use of mains water in your swimming pool. Rainwater diverters are an inexpensive alternative to installing a tank. They attach to a downpipe and can be used to divert rainwater into your swimming pool. In large downpours, you will need to monitor the water level in your pool so that it does not overflow. You should consult a plumber about stormwater diversion.
