Sudbury Aqueduct Linear District
Why it's listed
Built between 1875 and 1878, the Sudbury Aqueduct carried water about 16 miles from Farm Pond in Framingham to Chestnut Hill Reservoir in Boston, passing through Natick, Sherborn, Wellesley and Newton. It was built to serve Boston's growing population after the city annexed five neighboring towns in 1874. The horseshoe-shaped conduit is made of brick and stone masonry, with embankments, four tunnels, two bridges (Waban Bridge and the seven-arch Echo Bridge over the Charles River), a siphon, waste weirs, a gatehouse and a metering chamber. George Clough, Boston City Architect, designed several of the structures in a Victorian style. At capacity it delivered 80 million gallons a day. It left service in 1974 but is still used occasionally to move water into the Charles River. The district was listed for its role in Boston's water supply and its late 19th-century engineering and design.
Significance in brief: The nomination argues the aqueduct is important in the history of Boston's water distribution. It was the second in a series of water supply aqueducts and represents late 19th-century water technology, construction methods and municipal architecture. It retains integrity and meets Criteria A and C.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
