ANNUAL REPORT OF WATER DEPARTMENT OF JOHNSTOWN
Johnstown, N. Y., with a population estimated in 1916 at 12,500, has a water supply derived from three streams, there being two storage and one distributing reservoirs, which are respectively three and five miles from the city. The distributing mains are 4 to 10 inches in size. There are a total of 2,510 services, and 220 fire hydrants. The pressure varies from 110 to 150 pounds, being the gravity system.

The two storage reservoirs are known as the Cold Brook and the Warren, and the distributing reservoir, the Cork Centre. The sources of supply of these reservoirs are Warren, Cork Centre, and Cold Streams, fed by springs.
Cold Brook Storage Reservoir.
Built in 1878. Capacity 10,000,000 gallons. Sources of supply, Cold Brook, 350,000 gallons per day delivered to the reservoir through 3,000 feet of 12-inch tile conduit and 1,200 feet of 8-inch cast iron pipe; Warren Brook, 106,000 gallons, delivered through 4,000 feet of 12-inch cast iron pipe; this 12-inch pipe runs on a level with Warren reservoir, and serves as an overflow from the main reservoir to Warren Brook and reservoir or as a feeder from Warren Brook to main reservoir. Supply delivered to the city through 12,470 feet of 10-inch cast iron pipe. Water from Cold Brook can also be switched to Warren reservoir through 600 feet of 6-inch cast iron pipe and the 12-inch pipe above mentioned. Five hundred and fifty feet of 8-inch cast iron pipe connects the pipe from Cold Brook to the 10-inch main below the reservoir, with a 10-inch check valve on the main above the connection. The purpose of this bypass is to deliver the Cold Brook water to the city, as Cold Brook reservoir has thirty feet less head than Cork Centre reservoir; the head is automatically balanced in the pipe on the steep grade above the reservoir.
Warren Storage Reservoir.
Built in 1892-3. Capacity, 2,550,000 gallons. Source of supply, Warren Brook, 106,000 gallons per day or overflow from Cold Brook reservoir, or Cold Brook by means of pipe, as explained in note on Cold Brook reservoir. Supply delivered to the main through 972 feet of 10inch cast iron pipe connected to the main below Cold Brook reservoir.
Cork Centre Distributing Reservoir.
Built in 1895. Capacity 700,000 gallons. Located on Cork Centre Creek, flowing 1,887,000 gallons per day minimum. Supply delivered to the city through 5.6 miles of 16-inch cast iron pipe. There is a concrete sluiceway for sluicing turbid water by the reservoir; 200 feet downstream from the end of the sluiceway is located a small auxiliary reservoir, connected to the main below the reservoir, but upstream from the outfall of the 24-inch blowoff pipe, so that the supply can be temporarily taken from the auxiliary while the main reservoir is being cleaned. This improvement with the concrete sluiceway was built in 1905.
Cold Brook Diverting Dam.
The original dam built in 1878 was located about 100 feet upstream from the present one, and was of timber and plank construction. It was found that a large amount of the waters of Cold Brook passed around and under the dam instead of into the conduit to the distribution reservoir. The present dam and intake were enlarged and reconstructed with reinforced concrete in 1916, replacing the one built in 1883 and in its present form retains and delivers all the waters of Cold Brook, 350,000 gallons per day, to the Cold Brook reservoir through 3,000 feeit of 12-inch tile conduit and 1,200 feet of 8-inch cast iron pipe. The brick gate house was built in 1908.
Catch Basin Cork Centre Reservoir.
Built in 1903. Its purpose is to catch leaves and sediment which are sluiced past the reservoir through a 30-inch pipe and the open sluiceway referred to in note on Cork Centre reservoir. The sluice gate is also open at any time when the water of the stream is turbid. Temporary supply auxiliary reservoir is also taken through the sluice, serving as a by-pass to the reservoir.
Sylvan Falls Intake.
Built in 1914. Capacity 106,000 gallons per day. Source of supply, Warren Stream. 1,650 feet of 6-inch cast iron pipe connects the pipe from the intake to the 20-inch main below the Warren reservoir. Owing to the Warren reservoir having 30 feet less head than Cork Centre reservoir, the purpose of this intake is to deliver the Warren Stream direct to the city, from an elevation corresponding to Cork Centre reservoir.
The municipal affairs committee of Boston, Mass., have been considering the water supply problem and have appointed a special committee to give the matter thorough investigation. The advisability of filtration, the repair of the Payson Park reservoir, the possibilities of the city entering. the metropolitan system. and the feasibility of installing a high-pressure fire system are matters which will be reported upon later.
