Steep Bank Flat Bank
Wastewater Treatment Plant
Missouri City, TX
Pape-Dawson expanded an existing City WWTP from 3 MGD to 4.5 MGD and designed the first two phases of a new 3 MGD regional MBR WWTP with BNR and reclaimed distribution systems. The treatment process at the existing plant was converted to complete mix with nitrification, doubling capacity of two existing oxidation ditches and allowing structural rehab repairs to occur in each basin.
The existing plant had outdated equipment and insufficient mixing/aeration. Pape-Dawson resolved these issues by adding fine bubble diffusers, external turbo blowers, and submersible mixers to improve oxygen transfer. Additionally, phased flow diversion prevented service disruption during upgrades, ultimately resulting in a more efficient and cost-effective treatment infrastructure.
The project consisted of an expanded headworks structure, a new UV basin channel, an expanded sludge-holding basin structure, replacement of all existing headworks equipment, bypass and recoating of existing headworks channel, structural rehabilitation/isolation of the existing splitter box, and conversion of two oxidation ditches to aeration basins
