Project Summary
The Town of Concord (the Town) is in the process of making comprehensive improvements and upgrades to its existing surface water supply (known as Nagog Pond), which has been utilized by the Town as a water supply since the early 1900s. As part of these improvements, the Town replaced a portion of the original 16-inch cast iron intake pipe with a new 16‐inch inside diameter (ID) high density polyethylene (HDPE) intake pipe complete with a new stainless steel intake screen system.
Physical inspections of the intake pipe have indicated that it has significantly deteriorated, resulting in decreased hydraulic carrying capacity and risk of failure. Due to the condition of the existing intake pipe, beginning in 2021 the Town embarked on a two-phased approach to restore hydraulic capacity and improve resiliency.
Phase 1 of the Nagog Pond Intake Improvements included fusing and floating of the intake pipe along the water surface, and then submerging it into position; this work was completed in 2021. The second phase of the Nagog Pond Intake Improvements (Phase 2), includes cleaning and lining of the remaining portion of the original intake, which lies in the shallow cove portion of the pond, and is scheduled to take place in spring of 2023.
