Mansfield Bud Ervin Water Treatment Plant

Located southeast of Fort Worth, Mansfield is one of the fastest-growing suburban communities in the Dallas-Fort Worth Metroplex. Plummer has worked with the City for over 20 years to evaluate, plan, and design facilities that have allowed the City’s Bud Ervin Water Treatment Plant (WTP) to keep ahead of the rapidly increasing water demands. We provided a detailed process evaluation, site master planning, design, and construction phase services for two multi-phased, 10 MGD conventional treatment expansions and a 15 million gallons per day (mgd) membrane plant expansion to the WTP bringing the current capacity to 45 mgd. We also designed two clearwells and an upper-pressure plane high service pump station as separate projects. 

The site was master planned for an ultimate capacity of 60 mgd. Our Team provided the design and construction administration of a 1.5 million gallon cast-in-place concrete clearwell with baffles and a new high service pump station for Mansfield’s upper-pressure plane. The pump station was designed to accommodate five vertical turbine pumps at ultimate buildout of the facility. 

In subsequent projects, we designed the replacement of three pumps for the lower-pressure plane high service pump station and the addition of a pump at the upper-pressure plane high service pump station. One phase included the design and construction of a 10 mgd flocculation/sedimentation basin with tube settlers and filters utilizing sand and granular activated carbon (GAC) media along with a 1,250-kW emergency generator. Another phase included increasing the capacity to 45 mgd with the design of a 15 mgd membrane system with GAC contactors. The plant utilizes chlorine dioxide to treat iron and manganese.
