The first phase of the project includes the extension of an existing reclaimed water line to provide service to Texas State University. The second phase is an elevated storage tank near Highway 123 and De Zavala Drive, on the east side of Highway 123 approximately 500 feet south of the De Zavala intersection. The final phase consists of upgrading 3 existing pumps at the City of San Marcos Wastewater Treatment Plant.

The construction of the elevated storage tank (EST) was awarded to CB&I. The tank will maintain reasonable system pressure during peak demand and ensure reclaimed water availability to remotely located customers.

The scope of work includes the construction of a new 500,000-gallon single pedestal spheroid elevated storage tank, with yard piping, a chlorinator, tank mixing equipment, electrical and SCADA (Supervisory Control and Data Acquisition) controls, complete in place. The San Marcos High School Rattler logo (newest version) will be installed on the spheroid of the tank facing IH-35.
