Plant Master Drain Study

The Allegheny County Sanitary Authority (ALCOSAN) is soliciting statements of qualification from firms interested in providing professional engineering services to develop a plant-wide master drain study. The selected firm will provide all services necessary to survey existing drain systems, summarize issues, and produce a GIS model. The project's goal is to have a consultant prepare mapping and an assessment of the conditions and capacities of the drain systems throughout the Woods Run Wastewater Treatment Plant (WWTP) site. • The project includes site stormwater, building, garage, and treatment processes that terminate at either the WWTP Main Pump Station or outfalls to adjacent waterways. • The consultant will research existing ALCOSAN records and drawings, conduct site surveys, and prepare a georeferenced three-dimensional CAD model of the drain systems. • The consultant will also perform physical condition assessments in accordance with NASSCO standards and provide recommendations for improvements based on physical and operational conditions and current and future capacity needs.
