Rowlett council approves $140,000 odor‑abatement system for lift stations
Summary
The council approved a resolution to buy a biological/advanced-oxidation vapor‑phase odor-control unit for up to $140,000 after staff said the city has about $317,000 available for the program. Council voted unanimously to adopt the purchase.
The Rowlett City Council voted unanimously to approve a resolution authorizing the purchase and installation of a biological and vapor‑phase odor‑control system for city lift stations, with a contract price not to exceed $140,000.
Staff said the purchase is part of a citywide odor‑abatement program that combines chemical treatment (ferric chloride), manhole gas monitoring and an advanced oxidation process (AOP) filter for lift‑station headspaces. "This system also captures and oxidizes any odor compounds present within the lift station headspace prior to being released into the atmosphere," said Manal, a staff member presenting the item, describing the unit’s intended effect on hydrogen sulfide and other odorous gases.
Manal told council the Rowlett Lift Station receives flow from multiple contributing lift stations and that staff has been evaluating retention times and treatment options. Gary, interim director of public works, said staff reviewed case studies and visited other sites using similar technology. Council member Holston moved to adopt the resolution; John Bowers seconded. The motion carried unanimously.
Staff reported funding: an available budget of a little over $317,000 and a not‑to‑exceed purchase amount of $140,000 for the proposed unit. Council members asked about benchmarking and prior use in nearby cities; Gary said the technology has been successfully used elsewhere and staff had verified site satisfaction. The resolution directs the city manager or designee to execute documents necessary for the purchase and installation.
The council took the action as part of an ongoing effort to address recurring odor complaints from neighborhoods including Liberty Grove, the Rowlett Road/State Highway 66 corridor and parts of Katy Park.
