Radhi Majmudar served as the Regional Structural Engineering Manager for providing structural engineering support services in structural retrofit design and construction for Phase I and Phase II of the Bowery Bay WPCP Wastewater Plant Upgrade. The upgrade was a multi-phase modernization intended to improve process efficiency, reduce manpower requirements, and improve reliability. In particular, the plant was retrofitted to reduce nitrogen loadings into the East River and Long Island Sound to conform to the regulations set by the New York State Administrative Consent Order - Nitrogen Reduction Agreement. Phase I involved replacement of much of the process equipment including raw sewage pumps and drives, new preliminary scum collection and pumping equipment, replacement of return sludge and mixed sludge pumping systems, and replacement of the disinfection systems. In addition Phase I also included the design of a new residual handlings building to provide for collections and concentration of screenings and grit. Phase II involved improvements to the solid handlings facilities including replacement of existing gravity thickener mechanisms and repair of deteriorated concrete walls and walkways. This was in 2003.
