South Mesquite Wastewater Treatment Plant Upgrades

Project Overview

WHAT: Plant improvements include the addition of three new cloth-media disc filters in place of older filter technology to remove suspended solids; demolition of out of service secondary clarifiers to make room for the new UV basin; construction of the new UV basin and install of the new UV equipment to disinfect the treated water, and construction of a new electrical building to house the power source for the new equipment.

WHY: To increase our filtration capacity and convert from chlorine disinfection to ultraviolet (UV) disinfection to meet regulatory requirements and improve plant safety.

STATUS: All equipment improvements are online and in operation. Three new filters replaced older filter technology to remove suspended solids. The UV disinfection system replaced the chlorine system, allowing for permanent removal of disinfection chemicals from the site. Demolition of the chlorine contact basin is underway, and remaining work includes site grading, sidewalk installation and grass seeding.

WHERE: Located in Mesquite, serves cities of Forney, Heath, Mesquite, Rockwall and Seagoville.

WHEN: Design began in 2014. Construction began June 2017. Anticipated project completion in September 2020.

HOW MUCH: $10 million
