MWRA Renewing a Lincoln-Era Water Pipeline
As part of the ongoing rehabilitation of water distribution pipelines, the Massachusetts Water Resources Authority is rehabilitating a Lincoln-Era water pipeline that has carried water to Boston and Brookline since 1865.
Despite its old age, the heavy 30-inch cast iron pipe, called the Warren Cottage line, is still structurally sound. And instead of an expensive replacement project that would disrupt the surrounding area, the MWRA is cleaning and cement-mortar lining approximately 6,500 linear feet of 30-inch pipeline and replacing blow-offs and air release valves along the pipeline route. The project will improve the pipelines condition and carrying capacity and ensure that its service area continues to receive high quality water and adequate pressure for decades to come. The process involves the excavation of access pits along the route.
Rehabilitating and replacing old water pipes is an essential part of the MWRAs Integrated Water Supply Improvement Program. Other elements of the 10 year program include: 1) comprehensive watershed protection; 2) a major new deep-rock aqueduct, the MetroWest Tunnel, to assure continuous water transmission to communities; 3) projects in the distribution system including pipeline rehabilitation and new covered storage facilities to protect water quality and ensure water security; and 4) construction of modern treatment facilities for enhancing water quality.
