Rainwater Tanks - How they work

Rainwater tanks store rainwater run-off from catchment areas like your roof. In most cases, the water from your roof is funnelled along your gutters and into downpipes connected to your tank. If you are going to install a rainwater tank, alterations to your guttering may be required. To get the best out of your rainwater tank, it's important to install appropriate screens to stop debris and insects entering the tank.

Water pressure issues and top-up system
If you are connecting your tank to the toilet or washing machine you will need to maintain a minimum level of water in your tank and will therefore need a top-up system. A top-up system will deliver water to your tank through a pipe from the Sydney Water supply. An air-gap is required between this pipe and the rainwater tank. This is to ensure no backflow can go into the drinking water supply from your tank.

Sydney Water requires that the flow from your top-up system be limited. If the flow rate is too high, it can affect the water pressure supplied to you and your neighbours.

Your plumber can advise of the requirements of the top-up system for your property, including determining the air-gap required and flow rate restriction required.
