Coastal Treatment Plant's Facility Planning Assessment (FPA) Contract Awarded to AECOM

At its March 5, 2025, SOCWA Board of Directors meeting, Project Committee 15 (PC-15) approved a professional services agreement with AECOM, to prepare the CTP Facility Planning Assessment - Phase 1.

The CTP Facility Planning Assessment (FPA) is intended to be a forward-looking framework for facility modernization and long-term reliability. Key goals include completing a 30-year capacity utilization and peaking analysis, conducting high-level process-by-process evaluations of existing assets, and identifying opportunities for capacity right-sizing. The effort will also assess facility resiliency and reliability under varying flow and loading conditions, regulatory uncertainty, flooding risks, and operational constraints, while evaluating biosolids management options, energy efficiency improvements, resource recovery opportunities, and long-term regulatory compliance needs.

The project CTP master planning program is structured as a two-phase approach. Phase 1 will be the Facility Planning Assessment. Key elements of the assessment will include:

• Conducting a phased facility master planning effort to identify potential treatment facility improvement alternatives that will optimize long-term treatment and beneficial reuse opportunities for the CTP.
• Completing a 30-year base capacity utilization and peaking analyses for the CTP based upon current and forecast flows, loads and flow characteristics (peaking), and other future potential uses of the CTP.
• Performing high-level process-by-process assessments to determine existing available capacity, general asset condition, available useful life remaining, and to support assessment of future infrastructure opportunities and capacity right-sizing options.
• Identifying treatment alternatives that ensure facility resiliency and reliability and manage risks related to variations in flows and loading, flooding, regulatory changes and other operational uncertainties.
• Evaluating potential biosolids treatment technologies, if deemed feasible and cost-effective, to achieve Class B solids or as needed based on future regulatory outlook.
• Identifying project alternatives that reduce energy consumption, improve resource recovery and enhance environmental sustainability.
• Determining long-term regulatory compliance and permitting needs and assessing readiness to meet them.

Phase 2 would build upon the Phase 1 findings to develop a comprehensive Facility Master Plan, which will include recommended improvements and implementation strategies.

Phase 1 is expected to be completed in the summer of 2027.
