Five time award winning plant.
The La Center WWTP was designed to be expanded to treat over 6 MGD on less than an acre. The new facility is being designed in phases to be efficient and capacity added as needed.
Phase 1 added the new MBR system, complete with a new headworks building, screening system, and blower room all sized for 20 year flows based on the City’s Comprehensive Plan. The flow capacity of Phase 1 is 0.86 MGD maximum monthly flow with a peak daily flow of 1.5 MGD.
Phase 2 will address additional solids handling needs and Phase 3 would double the capacity of the plant by duplicating the Phase 1 upgrades for the Membrane Bioreactors (MBR) and should have capacity to treat the 2028 population.
