NAVSEA – Building a Shipyard the Nation Needs: NNSY’s New Industrial Waste Water Treatment Plant (IWTP)

Norfolk Naval Shipyard (NNSY) kicked off its next Shipyard Infrastructure Optimization Program (SIOP) project Nov. 4 for a new Integrated Wastewater Treatment Plant (IWTP). The IWTP is part of an Energy Savings Performance Contract (ESPC) with the energy solutions company Ameresco, providing critical energy and infrastructure upgrades and improving the energy efficiency of NNSY and its annexes.

The IWTP replaces a 44-year old facility that began operating in 1976.   The new facility will increase wastewater treatment capacity and incorporate newer, more efficient technologies, which will result in an estimated $1.3 million savings annually for the Navy.
