Water Supply of Sioux Falls.
Owing to Sioux Falls, S. Dak., owning the waterworks system and the fact of an independent company also doing business there, that city is considered doubly fortunate. The municipal water plant is the superior of any similar plant in a city of its size. The pumping station is equiped with two large pumps of the most upto-date pattern. One is always in operation, and the other is held in reserve in case of an emergency. The system, so far as the mains are concerned, is not complete. The business and main residence portions of the city are supplied, and another year will witness the extension of the mains of the municipal plant to every portion of the city. The capacity of each pump is 6,000,000 gal. daily, while the consumption is much less than that amount. The water supply is secured from the bottom lands a mile up the river. The water is secured from a battery of wells, which are connected with the main or pumping well. It is filtered into the several smaller wells through a formation of sand and gravel. Several tests of the water have been made, arid the report shows it has less germs than that of any otlier city in the West. The pure water and splendid drainage account for the exceptionally light death rate in this city. There are 21 miles of water mains already in use, ranging from 2-in. to 24-in. The city has 150 fire hydrants, and the water rates range from 6 to 25 cents on meters per 1,000 gal., and from 5 to $20 for lawn and garden purposes. The cost of the plant was about $130,000.
