Municipal Water Use

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.
