Rainwater collection systems are usually considered to be a rural technology. The discussions of cost versus benefit and of feasibility commonly centre on the individual household. However, for studies carried out by and for governmental water agencies, the target area is more likely to be a town or a city. More: broadly based estimation techniques for estimating rainwater collection system viability are required in this case.

This paper will show that rainwater collection may contribute to urban water supplies and will provide an outline of some of the calculations that can be done to estimate that contribution based on consideration of the city as a whole.
