Elements and Performance Criteria
- Determine design requirements
- Determine water transfer, recharge, reuse and harvesting system needs
- Describe processes of collecting, disposing and storing drainage water to avoid degrading water quality
- Investigate regional geology and geography to predict drainage parameters
- Apply hydrological calculations to predict volumes and rates of surface run-off
- Conduct site investigations to assess depth of clay, depth of ground water, soil and water salinity, and structural or chemical impediments so as to determine the most cost effective drainage system
