Norumbega Reservoir Dikes Number 3

Can you hear the gentle lapping of water against the earthen barrier? This is Norumbega Reservoir Dikes Number 3, a vital piece of Boston’s water history. Norumbega Reservoir Dikes Number 3 is one of five earthen dikes that hold back the waters of Norumbega Reservoir. This reservoir isn’t just a scenic spot. It plays a crucial role in ensuring a consistent flow of water to the Hultman Aqueduct. The Hultman Aqueduct, built between 1938 and 1940, bypasses the Sudbury Reservoir and Aqueduct, sending water from the Wachusett Reservoir into Boston and surrounding areas. Norumbega Reservoir, with its 50-acre expanse and capacity of 150 million gallons, acts as a central chlorination point for the water supply system. The gatehouse, perched between the main reservoir and the smaller Schenck’s Pond, is a fascinating blend of granite, concrete, and steel, designed by Boston’s Densmore, LeClear, and Robbins. Inside, screens filter out debris and fish coming from Wachusett Reservoir. The area surrounding the reservoir and Schenck’s Pond is thoughtfully landscaped with conifer trees. While currently closed to the public, discussions are underway to consider future access. Norumbega Reservoir Dikes Number 3, more than just a dam, stands as a testament to the intricate engineering behind Boston’s water supply. It’s a hidden gem, quietly working to keep the city’s faucets flowing.
