West Central Conservancy District SBR Wastewater Expansion

The West Central Conservancy District expanded its wastewater treatment plant to increase capacity, improve efficiency, and enhance operational reliability. CHA provided design services to support plant modernization while maintaining service continuity.

Improvements included new Sequencing Batch Reactor (SBR) equipment in two tanks, replacement of aging air piping and controls, and installation of two new blowers. Chemical feed systems were extended, fixed fine-bubble diffusers installed, and full electrical and controls coordination completed. Site improvements and new drainage structures further supported overall plant performance and resilience.

New treatment tanks and integrated controls brought all six SBR processes online under a unified system. Upgrades included two waste activated sludge (WAS) pumps, an aluminum sulfate feed system with storage tanks and chemical feed pumps, phosphorus monitoring equipment, a scum skimmer, and VFD-controlled scum pumps. These comprehensive upgrades strengthen regulatory compliance and long?term operational reliability.
