What is water trading? Where can water be traded? Water trading is the transfer of a water licence and/or allocation, usually in return for Trading water licences and allocations to a monetary payment. A water broker can assist different location is subject to an assessment with water trading (buying and selling water to ensure sustainable water use and to minimise allocations) and information on current market detrimental impacts on water resources or other prices. users, including the environment. This assessment is based on the principles in Trade can be permanent or temporary (a lease) Sections 6 and 7 of the WMLR Water Allocation subject to the water allocation plan’s trading Plan (WMLR WAP) and can be quite complex as (transfer) principles, and a licensee may trade it has to consider potential regional and local all or part of their allocation. scale impacts of the proposed trade.

The trading of groundwater can occur Well buffer zones: Water trading must not throughout the entire WMLR PWRA. However, cause well buffer zones to overlap (or further the trading of surface water or watercourse overlap). These buffer zones, defined in the water is restricted to within catchments (i.e. WMLR WAP, are deemed to be a circular area South Para River, Little Para River, River of potential impact resulting from Torrens, Onkaparinga River, Willunga Basin, groundwater pumping and drawdown.

They should also not overlap (or further overlap) To better manage water resource variability established buffers which protect groundwater- across the region, the WMLR PWRA is divided dependent ecosystems (e.g. wetlands). into 45 groundwater management zones and High intensity underground water use: 333 surface water management zones. Water trading should not move groundwater Some of the key assessment principles for allocations into existing (or create new) zones trading groundwater and surface water are of high intensity underground water use. detailed below. These are areas where concentrations of Groundwater allocations allocations significantly exceeds recharge to the groundwater system. Extraction limits: Trading must not result in the extraction limit for the receiving Surface and watercourse water management zone to be exceeded (or further The assessment of water trading for surface exceeded).

The buyer and seller negotiate an in-principle agreement regarding the quantity and price of water to be traded. If you are having trouble finding a buyer or seller then a water broker could assist, or you could talk to other water users, or place a notice in a local newspaper, noticeboard or on social media.
