Learn about how your water is gathered, treated, managed, and distributed by Delano Municipal Utilities.
Delano has four wells ranging from 135 to 180 feet deep. These wells are drilled into an underground aquifer, known as the Jordan Aquifer, to pump groundwater to the surface. The water undergoes a natural filtering process before collecting in the aquifer as it trickles through layers of soil and sand particles.
Once pumped to the surface, the water is treated for iron and manganese removal by pressure filters at a rate of up to 5 million gallons per day (mgd). Our actual daily average rate is 500,000 gallons per day with a current peak of 1.5 million gallons per day.
The treatment process reduces the hardness in our water from 46 grains to 26 grains. This is done by the following procedures:
The utility tests the water at numerous locations every month to ensure all state and federal water quality standards are met.
The Delano water tower is a 1.5-million-gallon storage tank. It was built in 2002 and replaced a 495,000-gallon tank built in 1970. The water distribution system consists of 20 miles of pipe, ranging from 4−16 inches in diameter, with 351 hydrants that are flushed every spring and fall.
