Bakersfield Wastewater Treatment Plant 3 - Innovative, Sustainable, and a Good Neighbor

摘要

Bakersfield Wastewater Treatment Plant 3 (Plant 3) Upgrade and Expansion Project aimed atrnaddressing capacity, process reliability, renewable energy and regulatory requirements. Prior tornupgrades, Plant 3 violated its effluent discharge permit because the inflow exceeded the ratedrncapacity and the plant lacked the required treatment. Several innovative, out-of-box processrnmodification, and costs and energy-saving ideas were incorporated into the design such asrnconversion of decommissioned trickling filters to biofilters for odor control, an extensive andrncreative odor control for “Zero Odor” plant, conversion of old secondary clarifiers to coveredrnprimary clarifiers, integrated renewable energy system with biomass energy and PV solar energyrnfor significant GHG reduction, and LEED-type buildings. This sustainable project earned morernthan $7 million in rebates/grants/incentives. The annual operating cost savings are estimated atrn$556,000. Completed on time with excellent team effort and safety record, Plant 3 hasrnoutperformed all regulatory requirements.
