Municipal (Residential, Commercial, light industrial) Water and wastewater

Draft Municipal Forecasts (Posted April 2010)
Draft Municipal water and wastewater demand forecasts were prepared for the Residential,
Commercial and Light Industrial water use categories. These categories are termed
”Municipal” to distinguish from heavy water-using industries, which are forecasted separately
as “Industrial.”The calculation of draft municipal water and wastewater demand forecasts utilize both population projections and a water use rate, which in most cases uses 2005 as the base year. These draft forecasts are aggregated by county for the planning period through 2050.
To provide Councils with a starting point for the selection of management practices, the draft
municipal demand forecasts have been disaggregated among relevant categories. These
include water source (groundwater and/or surface water) public supply versus self supply for
water, and centralized versus septic for wastewater.
The methodology and input for the draft municipal demand forecasts, such as baseline
water use rates (per capita water use rate), were presented to the Councils and to the
Municipal Ad Hoc groups. Feedback was incorporated into the draft results.
The county-level population projections used to forecast municipal water and wastewater demand were developed by the Governor’s Office of Planning and Budget (OPB) through contract with the Carl Vinson Institute of Government at the University of Georgia. These
projections considered comments received on the draft population projections released in
2009. Further questions or comments on these population projections should be directed to
the Governor’s Office of Planning and Budget.
Note: the report found by following the link in the paragraph above includes the projections through 2030. For use in water planning, OPB provided EPD with projections for 2040 and 2050.
