Performance Criteria

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Determine design requirements

1.3 Design water transfer, recharge, reuse and treatment systems to conserve natural resources and match requirements for stock

1.4 Position culture or holding structures and systems to make the best use of water resources

1.5 Match water requirements with workplace production forecasts, expansion plans and seasonal variation

1.6 Ensure collection and storage processes do not degrade the water quality for the workplace or the environment

1.7 Document design calculations and decisions according to workplace requirements, ensuring construction specifications define the work required to provide suitable water for workplace
