A Memoir of the Construction, Cost, and Capacity of the Croton Aqueduct
It is intended to carry three lines of pipes, each three feet diameter to tributing the distributing reservoir, (at present only two lines are put down,) and the arrangement will allow two pipes to be drawn from either division, so that in the event of emptying one division for repairs, the other would supply two pipes for the distributing reservoir, and all other pipes having a connection with each division would be in full supply, notwithstanding the suspension of one division. A pipe is put through the division bank, with a stop cock, to allow the water or not, as may be desired, to pass from one division to the other. The aqueduct intersects the reservoir at right angles with its westerly line, and 252 feet south of the north-westerly corner.
At this point a gate chamber is constructed, with one set of gates to pass the water into the northern division, and another set to pass it into a continued conduit of masonry, constructed within the embankment of the reservoir, to the angle of the southern division, where it enters by a brick sluice into this division. This arrangement gives the power of directing the water into either division, or both, at the same time, as may be desired. In the division bank, a waste weir is constructed to carry off the surplus water from either division, when it rises to the proper height. DISTRIBUTING RESERVOIR.
