Extension of Hackensack Water Supply

Extension of Hackensack Water Supply

Unable to supply its steadily increasing constituency, the Hackensack Water Company has begun improvements and extensions at New Milford and Oradell, N. J., which will give additional storage capacity approximating 4,000,000,000 gallons. It already has a storage reservoir at Woodcliff lake, just above, with a capacity of approximately 2,000,000,000 gallons, but in dry seasons that is insufficient, consequently the present improvement was begun. The new reservoir is being constructed in the Hackensack river, and will be five miles long, two miles wide and 17 feet deep when finished. A water power with a history of more than a century was purchased to insure the rights of flow. A new dam is to be built, all the old buildings are to be cleared away and the surroundings of the reservoir left entirely free from any possible means of contamination.

The Hackensack river is only a small stream, but little more than a brook, at Oradell, where the reservoir is under construction. The work of constructing the dredging machinery was entrusted to C. L. Fish, of Baldwinsville, N. Y. He has built a suction dredge 100 feet long, containing a 1,500-horsepower engine and pumping apparatus. It is capable of moving 5,000 cubic yards a day. and it is estimated that five years will be required to complete the dredging. The cutter, which goes ahead of the 9-inch suction pipe, is 5 feet in diameter and 6 feet in height. It is expected that this knife will reduce the largest stumps to a condition in which they can be taken up by the dredge and deposited on the bank. In all 400 tons of machinery will be in operation on the dredge. So large was this dredge and so small the stream that it was necessary to deepen and broaden the river with a smaller dredge before the large one could be built. Now that the big dredge is at work, it is excavating a passage to accommodate itself. At Woodcliff Lake, N. J., the same company lias another reservoir some two miles long and one wide, holding approximately 2,000,000,000 gallons, made by impounding the waters of Pascock creek, a small stream that drains a watershed of 30 or 40 square miles. During the dry season this supply is drawn so low that sometimes only the stream flowing through the intake is available.

The company’s filtration plant and pumping station is at New Milford. The filtering plant alone cost $250,000, and the pumping station was constructed at a large expense. Water is supplied to all the municipalities in the Hackensack valley. Most of the towns along the Northern Railroad as far north as Englewood, West Hoboken. Weehawken, Union Hill and other points in that vicinity. It is a strong and well managed company, giving its patrons good service and supplying water whose purity has been constantly tested by analysis and proved of an excellent potable quality.
