Electric Water-works.

Electric Water-works.

Recently was published a notice of the installation of an electric pumping plant at San Antonio, Tex., by the Goulds Manufacturing Company of Seneca Falls, N. Y.

The plant is intended to supplement the supply of water furnished the city by the two other pumping stations, which are situated about three miles from the business centre, by putting water into the mains at Market street, in the immediate vicinity of the principal buildings and materially helping to keep up the pressure in case of fire. It consists of three large Goulds’ triplex pumps, duplicates, of a combined capacity of 2,250,000 gallons per day. Each of these pumps has three outside packed plungers, ten inches in diameter by 12-inch stroke, and each is connected by gearing to a thirty horse-power 500 volt C. & C. standard motor.

The water supply is deiived from four 8-inch artesian wells flowing into a stand-pipe. The water rises in the latter to a height of about 45 feet, giving a pressure of about 19 pounds at base of that pipe.

A 20-inch pipe is connected to the stand-pipe that is just outside of the pump house. The water flows from this pipe to each pump through a separate valve and is discharged through the 10-inch check valve into a 20-inch pipe connected with the city mains.

The four wells are from 840 to 870 feet deep and are all within 100 feet of the pump house. The w’ater flows clear and sparkling, and gives to San Antonio the distinction of having the purest and most abundant water supply of any place in Texas. In the case of an epidemic, such as cholera, the supply could be cut off at the head of the river and taken entirely from these wells, excluding any possibility of pollution of the city water.

The power is taken at present from the electric light and power station, but eventually the water wheels which run the pumps at the head of the river stations, tnay be used to run electric generators and the power transmitted electrically to the city stations.
