The Specific Use Permit zoning case involving the Rowlett Creek Regional Wastewater Treatment Plant (RWWTP) administration building and contractor service area was rejected by the Plano City Council on August 9, 2021.
Construction is underway at the Sister Grove Regional Water Resource Recovery Facility. Crews are working on the various plant structures including the aeration basin, primary clarifier, secondary clarifiers, headworks, peak flow basin, and drain pump station.
The Capacity Assessment Study of the southern services area show the South Mesquite Creek RWWTP needs to be expanded from 33 MGD to 41 MGD average daily flow by 2026 to meet the growth projections through 2033.
To accommodate the growth in Forney, Heath, and Rockwall and increase wastewater conveyance capacity in the Buffalo Creek Interceptor System, the addition of a new Lift Station (LS) is necessary.
