Where does Georgetown get its water?
Purpose of the Integrated Water Resources Plan
The City of Georgetown faces unprecedented growth and demand for water coupled with a finite surface water contract volume from the Brazos River Authority (BRA) and limited yield of local Edwards Aquifer groundwater. The population is rapidly expanding in Central Texas, increasing competition for BRA surface water and groundwater supplies. The City initiated the integrated water resources plan (IWRP) to identify new water supply options and ensure long-term reliability under uncertain hydrology and growth. The three principal objectives of the Georgetown IWRP are the following:
- Construct and calibrate an integrated systems approach, with water, wastewater, reuse, and stormwater planned together that forecasts water supply needs and takes into account conservation, droughts, regulatory concerns, costs, and timing.
- Identify and evaluate potential water supply alternatives the City can implement.
- Evaluate the volume needed from, and timing for, each supply alternative out to 2070 and associated risks.
The integrated systems approach will help answer critical questions for the City, including the ideal mix of supply alternatives to yield reliability at the most reasonable cost. The IWRP was completed concurrently with other City planning efforts to maintain consistency with water and wastewater master plans. While the master plans look at each system in detail, the IWRP looks at the interrelationships of the system to identify multipurpose and multi-benefit projects.
