Rainwater Harvesting

Notice from the South Australian Government and SA Water. As of June 2006:
SA Water requires all plumbing work to comply with AS/NZS 3500:2003,
Where rainwater is required by legislation to service an outlet (ie toilet cistern, laundry outlet or hot water service), there must be a continuity of supply between the rainwater and the reticulated supply (seamless automatic switching).

What is seamless automatic switching?
Seamless automatic switching may be achieved by the following methods:

An Apex Rain Aid Valve
The rainwater tank may be supplied by a specially designed ball float control valve connected to SA Water’s supply and installed so it introduces only a small quantity of backup water when the tank is near empty to maintain a supply of water to the outlet eg toilet cistern (gravity supply).

An Automatic Switching device
A certified ‘WaterMark’ switching valve or device which automatically switches between the rainwater and the SA Water supply to ensure continuity of supply to the fixture/outlet when the rainwater supply is depleted (pressurised or pumped supply).

Automatic switching devices available from Aldgate Pumps:
