New Haven’s Water Supply.
With its present water supply and that which is soon to be added, it may truthfully be said, that there is not a city in the country of 100,000 inhabitants better able to withstand a long drought than that of New Haven, Conn.
The New Haven Water Company was incorporated in 1858, and at once began the erection of a dam across Mill river at Whitneyville, which, it was thought, would have sufficient storage capacity to supply the city with water for many years to come. This supply, which is known as section No. 1 and appropriately named Lake Whitney, covers an area of 300 acres, has a watershed of 56 square miles, with a capacity of 800,000,000 gallons. The water from this lake is forced by pumps to a distributing reservoir, the elevation of which is 125 feet, with a capacity of 10,000,000.
Section No. 2, known as the Mally lakes, and located in the town of Orange, is composed of three distinct bodies of water and are connected by the gravity system, the elevation being 129 feet, 160 feet and 170 feet respectively. These lakes cover an area of 45 acres, have a watershed of 1 % square miles and a storage capacity of 132,000,000 gallons.
Section No. 3, known as Lake Wintergreen, has an elevation of 240 feet, an area of 44 acres, a watershed of 1J, square miles and a storage capacity of 160,000,000 gallons. The gravity system is also the one that governs at this lake, and the water is used as a high service system.
Section No. 4, or Lake Saltonstall, so called, is situated in the town of East Haven and covers an area of 400 acres. The lake has a capacity of 1,395,000,000 gallons, a water shed of 3^j square miles, and with a proposed tunnel connecting Farm river with the lake it will have a water shed of 26 square miles. The water from the lake is pumped to a reservoir having an elevation of 146 feet and a storage capacity of 7,000,000.
Section No. 5, on the gravity system, is composed of a series of three lakes, two of which are completed, the third being in process of construction.
No. 1, known as Lake Dawson, is located in the town of Woodbridge. It has an elevation of 157 feet, an area of 60 acres and a storage capacity of 300,000,000 gallons. This lake will be connected with the two other lakes in this series by Sargent and West rivers, receiving its supply therefrom and distributing it to the city through 17,700 feet of 27-inch and 7000 feet of 24-inch conduit of Phipps hydraulic pipe. Lakes Nos. 2 and 3 are located in the town of Pethany. about three miles from Lake Dawson. No. 2 has an area of 35 acres, an elevation of 300 feet and a capacity of 180,000,000 gallons.
No. 3 (in process of construction) will have an elevation of 440 feet, an area of loo acres and a storage capacity 600,000000 gallons. The dam for this lake is being built of solid masonry, will be 1000 feet long, 65 feet high, and the most approved methods that engineering skill can devise will be observed in its construction.
From the figures above given, it will be seen that the company will have an entire storage capacity of 3,567,000,000 gallons.
When it is understood that the present population of the city is about 100,000, and that its average daily consumption is 11,500,000 gallons, it will readily be seen that the danger of a water famine in New Haven is so far in the distant future as not to be worthy of the least consideration. The combined system is all within a radius of ten miles from the centre of the city, and the sections are so connected that any one of them can be shut off for repairs without seriously affecting the city’s supply.
The company is very ably officered by Henry S. Dawson as president and treasurer; Eli Whitney, vice-president ; Ells* worth 1. Foote, secretary; A. F. Hemingway, assistant treasurer, and S. E. Granniss, superintendent.
