Water Treatment Plant Construction

Northeast Remsco Construction has worked with numerous Owners and Engineers to construct and upgrade both water and wastewater treatment plants in New Jersey and New York City. We have successfully completed work for public and private facilities and have been involved in Design- Build, GMP, and fixed price project delivery methods.

A Proven Treatment Plant Construction Process You Can Trust

Our team of experts work hand in hand with engineering and operations to ensure proper planning and execution to deliver the project the right way and on schedule. We self-perform the majority of the work and have our project management team on site to monitor quality and production while insuring that the work is done safely. We pride ourselves with providing creative solutions to extremely difficult deep and wet excavations and work in tightly congested existing facilities.

Our project resume includes state of the art membrane filter plants for both water and wastewater treatment, Odor control systems, DAF treatment and traditional treatment plant technologies, and have completed numerous bypasses of existing flows exceeding 80 MGD. We have converted sludge digester systems to combined heat and power generation to provide plants with alternative power sources and have installed cogeneration systems for landfill applications.

Treatment Plant Construction that Delivers Every Time

Northeast Remsco Construction has constructed and upgraded numerous water and wastewater treatment plants in NJ and NYC including state of the art membrane filter plants, traditional flocc/sed, and DAF treatment facilities. In addition, we have also completed treatment plant construction on numerous combine heat and power facilities in existing plants that run on digester or landfill gas.

Our team of experts self-performs the majority of our treatment plant construction work including excavation, piling, concrete, mechanical equipment, and piping installation. Our experience includes work for public and private facilities as well as design-build projects. Regardless of the job type, owner, specific needs or requirements of the treatment plant construction, or any other factor, Northeast Remsco Construction is here to help.
