7.0 VATER DEMAND AND SUPPLY FORECASTS (TASK 5)

The forecast reliability of Loveland's water supply sources under future
conditions requires the estimation of both water demands and the
acquisition of additional water rights to supplement current water supply
sources. Naturally, accurate prediction of these variables is quite
difficult. Planning for the development of additional water supplies must
begin before such needs arise in order to provide the necessary financial,
legal, and physical components of the supply system. Since the future
cannot be accurately predicted, water planning must consider a wide range
of future demand and supply scenarios in order to develop a water supply
system that is neither over-designed nor unreliable.

For this study, six alternative scenarios were considered as well as the

existing condition (i.e., "existing conditions" refers to 1985 water

demands, existing water supply sources, and existing City facilities). The

planning horizon was set at 30 years and growth in total water demand was

assumed to increase at either "low," "moderate," or "high" rates,

compounded annually. The City specified that "low" growth would correspond

to a 2 percent annual increase in total water demands, "moderate" growth

would correspond to a 3.5 percent annual increase, and "high" would mean a

5 percent annual increase. The seven scenarios considered were:
