mukden 21 Posted July 3, 2019 I noticed from https://www.sa.gov.au/topics/energy-and-environment/water/rainwater-tanks and http://onkaparingacity.com/onka/home/az_listing/rainwater_tanks.jsp that" New houses built in South Australia are now required to install a rainwater tank of at least 1000 litres. The tank must be plumbed into the toilet, to a water heater or to all cold water outlets in the laundry, and the inlet and overflow must be fitted with mosquito proof screens.Rainwater tank The same rules apply to new extensions or alterations with an area greater than 50m2 that include a toilet, water heater or laundry cold water outlet." Hope this will help you guys who just came to Adeliade or SA and trying to buy a house. Please also reply if u can find a cheaper one. cheers, Share this post Link to post Share on other sites
