Our Water Sources

CCW supplies water for municipal and industrial use in a seven-county service area covering 140 square miles. From the west of Corpus Christi, water is drawn from the Lake Corpus Christi and Choke Canyon Reservoir System, both within the Nueces River Basin, and sent to the O.N. Stevens Water Treatment Plant. To the east of Corpus Christi, water is transferred from the Colorado River to Lake Texana via Mary Rhodes Pipeline Phase II and from Lake Texana via the Mary Rhodes Pipeline Phase I and sent to the O.N. Stevens Water Treatment Plant.

The City is moving forward with seawater desalination. See details on the Inner Harbor Seawater Desalination Plant here: www.desal.cctexas.com. The City is also looking at aquifer storage and recovery and brackish water desalination.
