Somersworth, NH - Building Preservation & Filtration

Methuen Construction prepared a 110-year-old building to accept the first Ballasted Microsand Pretreatment system in the Northeast while maintaining 3 million gallons per day of plant flow and associated treatment. After optimizing the new pretreatment system, Methuen refurbished a 30-year-old upflow clarifier filtering system by replacing and installing four Multi-Media Underdrain Filters. In addition, sections of the historic building were converted into Chemical Treatment rooms without negatively impacting the existing architectural detail.
