WaterCress is particularly useful in designing water systems for:
Situations where the designer wishes to explore a range of system layouts in which the economic value of many system benefits are hard to quantify. In such cases `trial and error’ design approaches are far superior to approaches involving mathematical optimisation.
Sub-divisions, where alternatives to connection to existing water supply mains and sewers may be costly and/or opportunities are sought to utilise drainage water for amenity enhancement or supply
Small isolated communities in drier areas
Design situations where environmental impacts must be minimised.
