ODESSA, Texas, Aug. 12, 2026 – Carollo Engineers has been selected to design and provide engineering services during construction for the new and improved Bob Derrington Water Reclamation Plant (BDWRP), to replace the aging facility. The selection builds on Carollo’s prior work at the site, including a Condition Assessment and Facility Master Plan that augmented the city’s modernization strategy. The project supports Odessa’s goal to modernize the facility while maintaining uninterrupted wastewater treatment and reuse service for the community and industrial customers.

Originally constructed in 1977, the BDWRP was most recently expanded in 1995. It is rated to treat an average daily flow of 12.7 million gallons per day (MGD) and a peak two-hour flow of 47 MGD. Most of the treated effluent is reused by industrial customers or for irrigation, while the remaining small portion is discharged to Monahan’s Draw.

The City has launched a multi-year initiative to replace aging infrastructure at the BDWRP, improve treatment performance, enhance redundancy and reliability, and make the plant more operator-friendly.

“These upgrades are a major step in Odessa’s long-term plan to deliver a modern, resilient reclamation facility that’s safer and easier to operate,” said City of Odessa Director of Utilities Alex Rowlett. “We’re focused on improving performance and reliability while keeping treatment and reuse service online for the community and our industrial customers.”

The upgrades include new facilities with modern major process and support systems across the plant, starting at the headworks and extending through disinfection, reclaimed-water delivery, and solids handling. The work includes improved odor control, replacement of aging mechanical and piping infrastructure, addition of proven treatment processes, and pumping and conveyance improvements to support reliable performance and redundancy. Electrical power and controls will be updated, including power distribution and monitoring and control enhancements such as SCADA, to help operators run and maintain the facility more efficiently while keeping critical processes online during construction and future expansions.

As lead designer, Carollo will guide the project from early planning through construction. The firm will collaborate with City staff and stakeholders through milestone reviews, public information meetings, and City Council briefings, delivering regulatory-ready plans and construction bid documents.

“We value the trust the City of Odessa has placed in our team and look forward to supporting the next phase of improvements at the Bob Derrington Water Reclamation Plant,” said Carollo Vice President Hutch Musallam. “We’re committed to helping Odessa advance a modern, reliable facility while maintaining uninterrupted treatment and reuse operations.”

Construction of the new BDWRP is anticipated to be completed by spring 2033.
