Montpelier Combined Sewer Overflow Project
ARRA Project #: AR1-016
When Montpelier was first developing as a City, the sewer system was constructed as a Combined Sewer Overflow (CSO) which means that both the storm water and sanitary wastewater were carried by the same pipes, which poses problems with overall capacity. Over the past 10 years, the City has been working towards separating the storm and sanitary sewer system, but there is still much work to be done.
The project consists of storm/sewer separation on five streets. The locations include Lower State Street (adjacent to the Dairy Creme), Main Street (in front of the Kellogg Hubbard Library), Graham Terrace, Richardson Street and McKinley Street. All of the projects locations will involve the installation of a new storm water collection system including new catch basins. A total of about 2,200 feet of new storm drain piping will be installed under this project along with 35 new underground storm drain structures. Graham Terrace and Richardson Street will have full width pavement overlays and the other streets will be paved over the new utility trenches and other areas disturbed during construction.
Special Project Note: Some traffic delays should be anticipated in conjunction with this project.
