Description
The City of Tracy seeks a professional engineering firm to conduct a comprehensive technical study for Phase 3 expansion of its wastewater treatment plant (CIP 74169). The study must evaluate existing plant conditions, develop a baseline upgrade plan, and identify Best Available Technology (BAT) options that meet NPDES Order R5‑2022‑0073 and future capacity needs of 13.6 MGD and beyond. The consultant will deliver detailed assessments, comparative analyses, cost‑benefit matrices, and an implementation roadmap within a six‑month timeframe after award.
• Assess current liquid‑process and biosolids facilities, identifying reliability and capacity gaps.
• Perform baseline technology evaluation and develop a BAT alternatives matrix (e.g., IFAS, MBBR, MBR, advanced filtration).
• Score alternatives using regulatory, cost, constructability, energy, and resilience criteria, and recommend a preferred expansion strategy with a phased implementation plan.
