Different areas of the Valley, have different sources and qualities of water. For instance, in the South Valley your water may be imported from Northern California. While growers in the Mid Valley either have to pump or receive water from local irrigation districts and water systems. In the North Valley, growers may directly feed off rivers. Every water system creates a unique challenge.
Surface water has better quality than what usually comes out of the ground. Snow melt has a pH of 7, making it balanced. But as the water moves down the mountains, through lakes and canal systems, it can accumulate organic growth and biologicals (especially if you are on the southern end of the valley). The more organics in the water, the greater need for larger filtration systems and water treatment so that you can run water through the irrigation lines without clogging them.
Ground water quality is not always ideal and it’s important to test your water quality often. As ground water levels drop, larger concentrations of total dissolved solids (ie, nitrates) appear in the water. To help improve the quality of your ground water, you may need to mix ground water with surface water (if you have it).
Do I Need a Reservoir?
Reservoirs allow you to store water for several different purposes. For instance, your water district only delivers on certain days, and you need to water daily. Maybe, there’s sediment in your water and you need it to settle before irrigating. Or you need to mix ground water with surface water.
