There are many ways you can improve the water efficiency of your pool or spa.
Keep in mind, during Level 1 water restrictions, you can only top up existing pools or spas if using a trigger nozzle or device that can be turned off instantly. You can also only fill a new or renovated pool or spa over 10,000 litres capacity by obtaining a permit and using an approved pool cover.

How to avoid water evaporation
Evaporation is a major cause of water loss from your swimming pool. It's highest in the early evening as the air cools and the water remains warm. You can reduce this by covering the pool's surface as this lowers its temperature and decreases evaporation. Here are a few ways you can cover your pool:
Pool blankets are affordable and available in bubble plastic or foam. They float on the water's surface, and if used with a roller, can be easily removed before pool use, then spread out again after you have finished swimming for the day.
These are generally more expensive than pool blankets as they require a roller for storage. They take some effort to roll out and put away but have an added safety benefit as it's difficult to fall into the pool when the cover is in place. They also cover the whole pool, preventing up to 95 percent of evaporation, compared with a blanket where there may be gaps between the blanket and the edge of the pool.
Covering your pool with a shade cloth or sail will further reduce evaporation as well as protecting swimmers from the sun.
How to check if your pool has a leak
Firstly, you will need to identify if the leak is coming from the pool plumbing or the pool structure. These simple steps can help you identify the location of a leak:
- Fill the pool to its normal level and mark it with a piece of duct tape.
- With your filter system running, wait 12 to 24 hours then check to see if the water level has dropped significantly.
- Refill the pool back to the original level of the duct tape and with the filter system off. Wait the same amount of time (also over the same part of the day, i.e. 8am-8pm) and measure the water loss again.
- If you are losing more water with the filter system running, the leak is on the pressure side of your plumbing somewhere PAST the impeller of the pump.
- If you are losing less water with the filter system not running, the leak is on the vacuum side of your plumbing somewhere BEFORE the impeller of the pump.
- If the water loss is the same, the leak is more likely in the structure of the pool, however plumbing leaks should not be ruled out.
- If a leak is detected soon after construction of the pool, contact a pool specialist to investigate.
