Leverett, MA Water Mains

Tata & Howard was retained by the Town of Leverett for design and permitting engineering services to expand the Amherst water distribution system into the Town of Leverett.  The project involved the extension of the existing 8-inch water main in East Leverett Road, approximately 1.8 miles, to provide service to homes at the intersection of Cushman Road and Teawaddle Hill Road in Leverett with wells that have been contaminated by the Town of Leverett Landfill.  

Tata & Howard reviewed available data with the Town for use in this project including existing GIS mapping, existing utilities, Town specification standards for materials and products, and boiler plate specification sections.  Base plans for the project were developed utilizing the Town’s GIS data.   

Borings were completed along the project route to determine existing soil conditions and the extent of rock/ledge, if any.  In addition, soil borings assisted in determining the amount of needed polyethylene wrapping of the new ductile iron water main due to corrosive soils.   

The design included the installation of water service connections to existing homes within the project area from the water main up to and including the curb stop at the property line. New hydrants were spaced every 500 feet and in-line gate valves were spaced no more than 1,000 feet apart.  Surface preparation included temporary trench pavement and permanent trench pavement in accordance with the Town of Amherst and Town of Leverett standards. The draft design plans and specifications underwent a series of internal reviews for quality control.  Tata & Howard provided the Amherst Public Works with a 50% and 90% draft for review prior to finalizing the project documents.
