WaterCress (Water - Community Resource Evaluation and Simulation System) is a PC based water balance model for designing and testing trial layouts of water systems which can access multiple sources of water, including those generally regarded as being less conventional.
The model is designed to meet the problems of exploring alternative systems layouts at the feasibility stages.
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.
