FST-designed water main project benefits MWRA, two towns along Route 1
Water is flowing better in parts of Lynnfield and Saugus after the Massachusetts Water Resources Authority (MWRA) activated two new water mains that run underneath Route 1 in Saugus. The MWRA, the towns, local dignitaries and residents, and lead design firm Fay, Spofford & Thorndike (FST) marked completion of the two-year construction project with a ribbon-cutting ceremony on December 10, 2012.
"This was a difficult project, given the narrow roadway and numerous underground utilities. On top of that, the work had to be done at night," said MWRA Executive Director Fred Laskey. "But in spite of these challenges, construction was completed on schedule and we can now provide better service to the Lynnfield Water District. Finally, working with Saugus to include a section of their water main in this project was a win-win."
MWRA ‘s service to the Lynnfield Water District, which serves about 30% of the town, was undersized and capacity had been routinely stressed during high water demand periods. Under the Lynnfield/ Saugus Pipelines project, an 8-inch diameter pipeline was replaced with 36-, 24- and 12-inch pipe sections. The total length of the pipeline is 1.3 miles, running from Trader Joe's to the Lynnfield Booster Pump Station.
Saugus also has water mains that run under Route 1, which have been prone to breaks over the last several years, often causing major traffic jams. The Town and the MWRA partnered to construct 6,000 linear feet of new 12-inch line parallel to the Lynnfield pipeline under the same contract. Combining these projects resulted in reduced design and construction costs, and helped to minimize traffic impacts.
The Lynnfield pipeline can now provide emergency service to the Town of Saugus if necessary. Previously, Saugus installed a 12-inch water pipe along Route 1 south, from the Lynnfield town line to the Lynn Fells Parkway, a project funded by a $3 million, zero-interest loan from the MWRA.
FST began designing the project in 2008 and construction began in December 2010 under a contract awarded to Albanese Brothers, Inc. of Dracut.
Because of the high and constant traffic volume on busy Route 1, FST's work required close coordination with the Massachusetts Department of Transportation, MWRA, Saugus Conservation Commission and other state and local agencies. All construction work was completed during nighttime hours (8:30 PM to 5:00 AM). Although the contractor encountered some unforeseen conditions such as abandoned underground utilities and rock and excess ledge, the work was completed on schedule.
The project was completed using open-cut construction, with the exception of the jacking of a 54-inch casing pipe to allow for the installation of the pipes under a bottomless concrete culvert. It also involved rock removal using blasting and hoe ram techniques, as well as chemical splitting due to the project's close proximity to the pump station.
The total cost of the project was $6.3 million, which was shared between the MWRA (72%) and the Town of Saugus (28%).
