Water engineering services for hydraulic modeling support

Solicitation #1177. Issued by Engineering & Construction Department. The Washington Suburban Sanitary Commission, MD (the "WSSC"), is soliciting sealed responses for Water Engineering Services (BOA). Responses are to be submitted via WSSC's eProcurement Portal via https://procurement.opengov.com/portal/wsscwater PRIOR TO 2:00 pm on Wednesday, November 18, 2026. Late responses will not be accepted. The primary purpose of this Blanket Order Agreement (BOA) is to provide specialized engineering services to support the ongoing maintenance, enhancement, calibration, and evaluation of WSSC Water's water distribution system through the use of its computerized hydraulic model within the WaterGEMS modeling platform. As WSSC Water's standardized hydraulic modeling software, WaterGEMS is a critical planning and operational tool that requires advanced technical expertise to ensure the accuracy, reliability, and effectiveness of system analyses. In addition to hydraulic model updates and calibration, the BOA will provide engineering support for a variety of water system planning and evaluation initiatives, including: Updating 20-year water demand projections to support long-range planning. Evaluating water loss reduction initiatives and their impacts on system performance. Assessing the feasibility and implementation of potential reclaimed water systems. Analyzing system redundancy and resiliency to improve reliability and operational flexibility. Reviewing proposed growth and development to assess impacts on the water distribution system and associated infrastructure. Providing technical analyses and recommendations to support strategic planning, capital improvement programs, and system optimization. Through these services, the BOA will ensure WSSC Water maintains a reliable, resilient, and efficiently managed water distribution system while supporting future growth, regulatory compliance, and long-term infrastructure planning.
