The water supply is obtained by pumping from deep wells that are 16 to 22 inches in diameter, and 90 to 150 feet deep. The wells are located at 11 different sites in clusters of 3 wells at 10 sites and 4 wells at 1 site. The wells are equipped with turbine pumps that range in capacity from 2.6 to 7.4 cubic feet per second, and motor sizes that range from 100 to 300 horsepower. Total dynamic head ranges from 241 to 309 feet at the 34 wells. Two booster pump stations have been recently added by the irrigation district to the distribution system.
All water service is metered.
Because of extensive urbanization of the area, the irrigation district has a program to install fire hydrants to meet fire safety needs. The project has been operated and maintained by Consolidated Irrigation District No. 19 since January 1, 1968. The growth of Spokane as a commercial and industrial center has led to subdivision of much of the irrigated land into homesites. The Spokane Valley Land and Water Co., organized in 1903, irrigated about 22,000 acres of land. The company sold a block of its land in 1908 to finance construction of a canal system.
