Odessa Water Treatment Plant Improvements

Built in 1958, the City of Odessa Water Treatment Plant (WTP) required a comprehensive upgrade to support its growing community. To modernize the 50 million gallon per day (MGD) facility, the City partnered with Garney.  

The project included significant advancements to streamline operations and new construction to replace outdated infrastructure, ensuring reliable and efficient water treatment for years. Outdated structures, like sedimentation basins and old chemical facilities, were removed to create space for modern replacements. Existing systems, like the Golder Pump Station, were rehabilitated to improve efficiency and maintain steady water flow throughout the facility. 

The supervisory control and data acquisition (SCADA) system had the biggest impact on modernizing plant operations. This advanced technology enhances security and allows operators to monitor and control the treatment process remotely, automating key functions to reduce manual intervention and minimize human error. 

Garney also built a new flocculation and sedimentation facility and new south chemical and electrical buildings to house treatment chemicals and equipment. The north chemical building was expanded to include updated chlorine and electrical rooms. To ensure smooth operation and control, a new switchgear room was built at the Golder Pump Station, and a server room for SCADA was added. 

The plant had to remain fully operational throughout construction to meet the community’s needs. Garney addressed this challenge by installing multiple bypass systems to redirect water flow away from the construction area temporarily. The SCADA upgrades were carefully planned and completed in stages. The phased approach was essential to maintaining a consistent, clean water supply to the community during construction. 

These upgrades significantly enhanced operational efficiency by integrating advanced technologies, positioning the City of Odessa to meet its growing demands. The improvement ensured the continued delivery of clean water, contributed to long-term sustainability, and enhanced water quality for the community.
