Roof Leader Disconnection Program

During 2013, Pennichuck Water Works (Pennichuck) worked with Comprehensive Environmental Inc. (CEI) to assess the benefits of implementing a residential roof leader disconnection program in the Pennichuck Brook Watershed, specifically focusing on the more urban communities of Nashua, Amherst, and Merrimack. The project quantified potential recharge volumes, potential disconnected impervious area, and potential water quality benefits that could be achieved in each community, within the boundaries of the watershed, through implementation of a roof leader disconnection program. The project also outlined existing available outreach tools that communities could provide to residents to help promote such a program. The results of the study were presented to the communities of Nashua, Amherst, and Merrimack as part of a Community Outreach Program.
