Sudbury Aqueduct Waste Weir Control House // 1878

Buildings of New EnglandLeave a comment

The Sudbury Aqueduct was constructed between 1875 and 1878 and runs for 16 miles from Framingham, Massachusetts to the Chestnut Hill Reservoir in Boston, and was in use for almost 100 years. It was designed to carry water from the watershed of the Sudbury River to Boston and its surrounding communities, supplying the ever growing metro area with fresh drinking water. Along the route, meter and control houses were built along with the Echo Bridge, to guide the running water to Boston for distribution all over the city. City architect of Boston, George A. Clough designed many of the structures along the route including this waste weir structure in Newton Centre. The weir was known as “Clarks Waste Weir” as it was built on the edge of land owned by Charles P. Clark. The aqueduct was taken out of regular service in 1978 but remains an emergency backup. Much of the aqueduct’s route is open to the public as an unimproved walking trail.

Beacon Hill Reservoir // 1849-1883

Did you know there was once a massive granite reservoir in Beacon Hill?

Long before the Wachusett and Quabbin Reservoirs that now supply water to Boston, the city’s original municipal water supply was Lake Cochituate, a reservoir in Metro-west. Due to Beacon Hill’s high elevation, the city selected the site behind the recently completed Massachusetts State House, to store and distribute water to the city. The site was too steep, so it had to be graded. Therefore, the top of Beacon Hill, where the beacon had long been standing, needed to be lowered to accommodate the reservoir. The soil was dug by hand and hauled by cart down to fill the old Mill Dam in the Bulfinch Triangle area. The reservoir, which opened in 1849, was unique in its approach. The design of the structure needed to minimize its footprint and reflect well on its surroundings in the prestigious location. In lieu of earthen bermed walls, as was the convention in most period distribution reservoirs, the design chose to create a watertight tank within a masonry structure. This made the structure the first elevated storage tank constructed in New England. Sheet lead was used to make the reservoir watertight (which likely led to a lot of health issues (hindsight is 20/20). By 1870, the poor water pressure made the Boston Waterworks build the Roxbury Standpipe, which relegated the Beacon Hill Reservoir to being an emergency water source for use only in case of fire or accident to the pumping-mains. In 1883, Boston Water Works sold the structure to the Commonwealth, who demolished it for the addition to the State House.

Echo Bridge // 1876

Spanning the Charles River between Upper Falls Village in Newton and Needham, the Echo Bridge, is one of the most stunning structures around Boston. While not technically a building, I couldn’t help but share one of my favorite off-the-grid places to explore in the region.

The bridge served as crossing for water to be transported from the Sudbury River to the growing City of Boston. The entire aqueduct transported water over 18 miles from Farm Pond in Framingham and was stored in the Chestnut Hill Reservoir in Boston. Due to the topography of Hemlock Gorge in Newton, a large elevated bridge was required, creating one of the biggest engineering marvels around Boston. George W. Phelps, a contractor from Springfield, MA was selected as the builder of the bridge with a low bid. The 500′ bridge features a total of seven arches, with the largest spanning the Charles River being 137′, the second largest masonry arch span in the U.S. upon its completion.

Echo Bridge is constructed of large granite block and brick, which was held in place by wooden framework until the arches would be able to support their own weight at the top of the arches. Echo Bridge gets its name from the acoustical phenomenon when you stand at the base of the arch at the river and when speaking, the sound reverberates and echoes back and forth.
