SA 2 Water efficiency

Limitation:

Limitation:

SA2 applies to new Class 1 buildings and, extensions to existing Class 1 buildings where the roof catchment area is not less than 50 m2 —

  1. located in Council areas, excluding the Municipal Council of Roxby Downs and the District Council of Coober Pedy and;
  2. where an extension incorporates a water closet or a water heater or laundry cold water outlet.

For the purposes of this part, Council means: A municipal or district Council as constituted under the Local Government Act 1999.

SA 2.1 Performance provisions

Objective

The Objective is to efficiently use all available water supplies.

Functional Statements

A building is to be constructed in a way that efficiently uses all available water supplies to reduce the amount required from the mains reticulated water supply.

Performance Requirements

A building must provide an additional water supply (other than the mains reticulated potable water supply) which must be plumbed to at least a water closet or a water heater or all the cold water laundry outlets.

SA 2.2 Acceptable construction practice

SA 2.2.0 Definitions

The following definitions are used in this part:

Rainwater tank means a vessel for the storage of surface water collected from the roof catchment area of the building.

Roof catchment area means the area of the roof (expressed in square metres), measured on the horizontal (no allowance for slope or vertical surfaces) and includes the plan area of the gutters.

SA 2.2.1 Application

Compliance with the acceptable construction practice provisions of SA2.2 for water efficiency satisfies Performance Requirement SA 2.1.

SA 2.2.2 Rainwater tank capacity

  1. Where the roof catchment area of the building is not less than 50 m2, the building must be designed to ensure that surface water run-off from not less than 50m2 of the roof catchment area is:
    1. collected by a drainage system complying with Clauses 3.5.1, 3.5.2 and 3.5.3 of the Building Code of Australia as applicable; and
    2. stored in a rainwater tank, the storage capacity of which is not less than 1 kilolitre (1000 litres); and
    3. plumbed to at least a water closet or a water heater or all laundry cold water outlets.
  2. Where the roof catchment area of the building is less than 50m2, all the surface water run-off from the roof catchment area must be collected, stored and plumbed in accordance with (a)(i), (a)(ii) and (a)(iii).

Explanatory information:

Explanatory information:

Clause SA 2.2.2 requires the rainwater tank to be plumbed to a water closet, water heater or all laundry cold water outlets.
