New Chlorine System Improves Water Quality Reliability
City of Corpus Christi
CORPUS CHRISTI, TEXAS (News Release) - Corpus Christi City Council approved a $100.6 million construction contract with Reytec Construction Resources, Inc. of Houston to replace the aging chlorine gas system at O.N. Stevens Water Treatment Plant (ONSWTP) with a safer on-site chlorine generation system.
The project eliminates health and safety risks from potential chlorine gas exposure to plant workers and surrounding neighborhoods. It also improves the reliability of water disinfection for the City’s drinking water supply.
The current chlorine gas system, installed in 1981, uses 90-ton railcar storage. The new on-site sodium hypochlorite generating system will produce at least 18,000 pounds of chlorine per day without the risks associated with transporting and storing chlorine gas.
The project includes:
· Installation of on-site sodium hypochlorite generating system
· New chlorine dioxide generators
· Demolition of existing 1981 chlorine gas infrastructure and rail car facilities
· Enhanced redundancy for uninterrupted water treatment
The Texas Commission on Environmental Quality approved construction plans on May 30. The funding comes from the Water Capital Budget Fund.
"This investment represents a major step forward in ensuring the safety and reliability of our drinking water system,” said Mayor Paulette Guajardo. “By replacing decades-old infrastructure with modern technology, we are prioritizing public health, protecting our neighborhoods, and strengthening our water system for generations to come.”
