Run Time Analysis Approach to Addressing Pump Station Operational Needs

Flow monitoring at pump stations has been a practical limitation to completion of data collection at pump stations without newly installed flow meters and SCADA systems capable of producing workable flow data. However, with the continued and progressive increase in CMOM requirements, Asset Management studies, Sewershed capacity studies, and post-rehabilitation evaluation, the need for functional pump station data is continually growing. Challenges in developing a solution for pump station monitoring range from operator interaction complexities, project cost constraints, preservation of data quality, and software and equipment needs. Using Charles County's Pump Station Service Area Analysis and Sewershed Infiltration/Inflow Study as examples, this paper describes the “run time analysis” (RTA) approach – a proven procedure for using readily-available equipment and procedures to accurately characterize discharge performance for sewage pump stations.
