Progress of the New Water System for New York
The headings of the Catskill Aqueduct Tunnel under East River, New York City, met on September 27. This most interesting link in the great water supply tunnel under the entire length of the Borough of Manhattan and a part of the Borough of Brooklyn, was completed late Saturday night with no other ceremony than the presence of the department engineer in charge of the city tunnel, Walter E., Spear, and the division engineer, Lazarus White, under whose immediate supervision this part of the work came. The meeting of the headings occurred about 750 feet below the river level and marks the beginning of the end of what has been the most difficult part of the deep tunnel project. The alignment met within 0.17 feet and the stationing within 0.03 feet. Of the whole aqueduct from the Hillview reservoir to Atlantic avenue, Brooklyn, there remains a little more than half a mile to be excavated. The city tunnel of the Catskill aqueduct was planned in the fall of 1909. The scheme was authorized by the Board of Estimate and Apportionment in July, 1910, and approved by the State Water Supply Commission in October, which was the last legal obstacle to overcome. Contracts were let and work begun early in 1911. The work was without precedent in the city water supply distribution systems and its quick completion according to the engineers’ plans and estimates is a notable engineering achievement.
