The city of Pflugerville has relied on groundwater from the Edwards Aquifer as its sole source water supply and the area has experienced an explosion of growth. As one of the fastest growing cities in Texas, Pflugerville has had a difficult time keeping up with infrastructure needs to serve its citizens. The water supply from the Edwards Aquifer is declining as water use in Pflugerville and surrounding communities increases. Water demand for the city of Pflugerville has doubled in five years and demands are projected to more than triple by the year 2020.  

The city hired HDR to evaluate their options for developing a long-term water supply and to address their internal water distribution system needs. HDR performed feasibility studies on the two primary options for water supply for Pflugerville including development of a system to deliver water from the Colorado River downstream of Longhorn Dam and development of a system to deliver water from the Carrizo-Wilcox Aquifer in Bastrop County. Based on the results of the studies, the city is in the process of implementing the Colorado River Water Supply Project. The project includes the construction of a river intake and pump station at the Colorado River, a 16-mile, 30-inch diameter pipeline, a raw water storage reservoir, 15 mgd water treatment plant, and treated water transmission facilities. The project is planned to meet the long-term water supply needs for Pflugerville through the year 2040 and is currently in the final stages of construction.
