South East Management Area
WATER RESOURCE MANAGEMENT
PROGRAMS IRWD works with ETWD and City of Orange on plans for groundwater development within the South East Management Area and updates demand projections and the water budget accordingly. IRWD: The compilation of land use data is the basis for IRWD’s wa ter resource planning including its portion of the South East Management Area. Per IRWD’s 20 20 Urban Water Management Plan (UWMP), the land use data obtained from multiple jurisdictions in IRWD’s service area is used in conjunction with IRWD’s applied water use factors in order to estimate water requirements. ETWD: ETWD’s water resource planning is based on the 20 20 UWMP demand projections. Regional demands are forecasted by the Municipal Water District of Orange County and are then tailored to ETWD’s service area using available data for land use, population, and economic growth, intermixed with a trajectory of conservation, which includes both additional future passive measures and active measures. City of Orange: The City of Orange’s current UWMP (20 20) provides the basis for water resource planning in Orange’s water service area. The UWMP, in conjunction with applicable water use factors, form the basis for any potential water use estimates required for potential planning use in the service area.
