How Virginia Beach Creatively Uses Sewer Modeling to Inform Their Capacity Assurance Program
Abstract:The City of Virginia Beach Department of Public Utilities (City) provides sanitary sewer service to over 425,000 citizens and has over 404 sewer pumping/lift stations. DPU recently conducted an evaluation of their sanitary sewer pump station service areas using hydrologic modeling tools to estimate the 2-year recurrence interval peak hourly flow rate at each pump station. DPU developed a Capacity Assurance Program (CAP) that utilizes the 2-year peak hourly flows to:
Evaluate available capacity in the sanitary sewer system
Make decisions regarding the acceptance of new sewer flows into the sanitary sewer system
Track and manage flow acceptance requests
Identify and prioritize sewer pump station capacity enhancements.
The use of the hydrologic modeling results within the Capacity Assurance Program is described herein.
