Can I fill a farm dam or tank with SA Water supplied reticulated water?
A farm dam or tank must not be filled with SA Water supplied reticulated water unless it is being used for domestic or stock consumption or fire fighting. A permit is required to fill a dam or tank for any other reason. If a rainwater tank has been plumbed directly into your house by a licensed plumbing contractor – in line with mandatory requirements for new homes – then it will include an automatic switching device to allow seamless transition between rainwater supply and mains water. In these cases it is acceptable to have a quantity of mains water in your tank.
