The Weston Aqueduct was designed to deliver water from the Sudbury Reservoir in Framingham to the Weston Reservoir in Weston, Massachusetts. Built between 1901 and 1903, the aqueduct was designed to provide water to the suburbs north of Boston. All of the buildings that shelter the aqueducts above-ground elements, including this structure in Wayland, were designed by the architectural firm of  Shepley, Rutan and Coolidge, with landscaping along the route and at the reservoir designed by the Olmsted Brothers, landscape architects. This siphon house, known as the Happy Hollow Siphon House was built in 1903 and was an important part of the aqueduct system, as it transferred water through varied elevations using gravity and pressure to move the liquid without a pump. The aqueduct route is now a long, linear path and remains owned by the Massachusetts Water Resource Authority.
