Leprino Foods Wastewater Treatment Plant Expansion

Leprino Foods doubled the production capacity of its existing plant, which treated a combination of cheese waste and sanitary waste. This necessitated a 0.7-mgd expansion of the SBR plant largely by using existing facilities. Work comprised design and specification for:

New influent pump station consisting of 1,500-gpm submersible pumps

Two new 250,000-gallon flow equalization tanks with spills routed to a 50,000-gallon spill control tank

Flow control/pump building centrally located between the flow equalization tanks and the spill control tank to house piping, valves, metering, variable-frequency drive equipment, electrical and blower equipment

Pre-engineered metal operations/lab building with separate room for three centrifugal, multi-stage blowers

Two parallel earthen aeration basins with fine-bubble diffusers and two 42'-diameter clarifiers

Three 500-gpm RAS pumps and two 250-gpm WAS pumps housed in a common building; magnetic flowmeters were installed for RAS/WAS flow monitoring and control

SBR tanks converted to aerobic sludge digesters of 0.7-mg capacity each

New effluent storage lagoon and 16" irrigation pipe to transport reuse water to agricultural land.
