The updated Spokane County Water Demand Forecast Model was presented by Mike Hermanson at the October IWAC meeting. View the full presentation Spokane County Water Demand Forecast Model 3.0 10-8-13
Forecasts for water demand were based on factors such as: demographic forecasts; housing and employment projections; water system data; monthly water use by sector from 15 water systems over a 20 year span; agricultural census; aerial photo interpretation; park irrigation records; self supplied industrial; and county subarea demand.
The earlier Water Demand Model did not distinguish between consumptive and non-consumptive demand. The updated model separated water demand for each sector and sub-sector into consumptive use and non-consumptive use and accounted for the return flow of non-consumptive water use.
