Portsmouth, NH - New Headworks Construction

The new Headworks Building will house equipment that provides preliminary treatment to raw wastewater entering the Pease treatment facility. This includes removal of rags and other debris through a wastewater screen, removal of sand and other debris in a grit removal device and raw wastewater pumping to lift the wastewater to the next phase of treatment. The project will also include a new odor control system for the entire wastewater treatment facility. This will be done by incorporating two new carbon odor control systems (carbon vessel, fans and ductwork); one system for the septage receiving, headworks and primary clarifiers and a second system for sludge storage and processing.
