Type A Megaflex Regulates and Diverts Stormwater Flow
To address the challenge of combined sewer overflow (CSO) events, the City of Indianapolis sought a cost-effective and minimally disruptive solution. After evaluating various options, the city identified improved utilization of its existing collection system’s storage capacity as the most efficient approach.
To achieve this, Indianapolis selected a 72” Type A Megaflex Valve. This valve was chosen for its adaptability—allowing control structures and a valve vault to be constructed around the live interceptor without major service interruptions. Once delivered, the valve was seamlessly installed during evening hours by removing a section of the existing interceptor and inserting the valve into place. This process ensured minimal impact on the surrounding community and infrastructure.
The Type A Megaflex Valve offers precise modulation of flow diversion, unlike traditional all-or-nothing solutions. By adjusting the inflation pressure of the valve, the city can balance flow between interceptors, optimizing system capacity and reducing overflow risk. This innovative technology has proven to be a reliable and effective solution for enhancing flow control and minimizing combined sewer overflows in Indianapolis.
