<br />Attachment C <br /> <br />Tip: One (1) inch of water is a typical measure for water output of your sprinkler system. When <br />adjusting and setting zones (or even when using a hose) and watering times, use a can (tuna fish <br />or cat food size works well) or cup and see how long it takes to collect one (1) inch of water. <br />This will give you a good idea of how long the water should be running in a particular area. <br /> <br />Drip (trickle) irrigation systems use narrow, very flexible plastic tubing with small holes that <br />allow water to drip onto the ground. These systems are low pressure, which allows the waterto <br />come out of the tubing holes slowly, in large drips. Because the tubing typically is resting on <br />stands or branches, the tubing is close to the ground. With large water drops and small travel <br />distance, water loss due to wind is minimal. Water savings of between 30-50% over spray <br />irrigation systems are not uncommon. Drip irrigation kits are inexpensive and relatively easy to <br />install. Drip irrigation works great for landscaping, but also for flowerbeds, gardens and even <br />patio and deck planters. The most common issue with drip systems are clogs in the holes, which <br />may be hard to locate. Using a filter is recommended and usually helps prevent system clogs. <br /> <br />- Micro irrigation is for small area watering using bubblers, small and focused sprinklers and jets <br />to precisely direct water to plants. Unlike drip irrigation, micro irrigation is used in compact <br />areas (example of micro irrigation set up is below). <br /> <br /> <br />Root zone irrigation, or dripper-line, is a specialized system and is one of the best water options <br />for distribution. The tubing is buried and uses small openings to put the water right at the roots. <br /> <br />Water controllers: <br /> <br />- Spigots are the original controller for water. The most common problem is leaving the water <br />valve open, but this can be resolved by using a timer on the hose or spigot. <br /> <br />Manual timers typically use mechanical stops to start and stop the water flow. They are another <br />inexpensive option. <br /> <br />- Programmable controllers usually have a timing circuit, which allow you to set a variety of <br />variables such as: time watering starts, duration, days of the week, et cetera. <br />
