Under the New York Power Authority’s (NYPA) Energy Efficiency Program, Savin Engineers was tasked with the completion of detailed design and construction management of a new low-pressure steam boiler plant at the Wards Island Wastewater Treatment Plant in New York City. The scope of this project includes the retrofit of the existing Boiler Building with five (5) new, low pressure steam boilers capable of generating 3200 BHP serving most of the plant’s building heating and sludge heating loads. The boiler plant includes large size header piping, combustion air system, chemical feeds and complex condensate return system. Existing digester gas boosters are proposed to be replaced with new rotary type packaged boosters with higher capacities to fully utilize the plant’s digester gas as fuel for the boilers for significant energy savings.
Other scope items include demolition of the existing boiler plant stack, architectural modifications of the Boiler Building, structural work to support boilers, plantwide steam piping distribution, effluent water heat exchangers for boiler testing, new fuel oil vault to house relocated emergency generator fuel oil pumps, civil work for underground steam and natural gas piping, new electrical distribution and lighting system, supporting plumbing systems and related instrumentation and controls work.
