In California’s summer dry climate, automatic irrigation systems are a must. Not only for providing our plants with much needed water in the heat, but also to conserve our water and cut down on water waste. An automatic irrigation system means efficient use of water not only for the environment but for your water bill as well. It also means minimum maintenance spent on your garden since your controller waters your plants, not you dragging a hose wherever you can and guessing at how much water you’ve given.

When we design your irrigation system we do in a way that will make sense for the needs of your garden, your budget, and your long term maintenance. We design a custom system for each client and we choose our products based on cost vs. overall practicality. We regularly attend product seminars and use cutting edge products that will maximize the efficiency of your system saving you water and maintenance costs.

As part of your automatic irrigation system we will mount an automatic controller, usually in the garage, for you to set or change at your convenience. In fact, many of the controllers we use are detachable from their mounts so that you can take them inside for programming if you wish. The controllers we install will be able to run multiple programs at the times you specify and can even be programmed to adjust for more water in the hotter months of summer, and less water for the cooler months of winter. Though we do recommend you shut off your irrigation system whenever it is raining.

Following are some notes on what makes up a quality irrigation system:

We use schedule 40 for all pipe, mainline and latterals.
We use swing arms for all sprinkler spray heads and rotors.
We set up our pipe sizing so as not to exceed 5 feet per second on water flow. This helps eliminate water hammer.
We install all sprinklers with head to head coverage. As an example a 12' radius head is installed on 10' centers.
We place our anti-syphon valve nests out of the way, so as to keep them out of sight.
We install anti-syphon valves 12" higher than the highest head, for water safety.
Where valves should be buried to hide them from sight a backflow preventer is installed to protect the whole system.
Irrigation zones are layed out according to sun, shade or similar plant water needs.
We run extra wire to valve nests.
We use water-proof wire conectors to all electric valves.
We primer and glue all joints.
We install valves so they can be changed or repaired easily.
We write down the program, times and zones of the controller.
We install heads 2 fingers (1.5 inches) from hardscape or benderboard.
We count up the gallons per minute of each nozzle in use for each valve so as to prevent spray heads that don't spray far enough.
We use grey schedule 80 pvc for above ground applications such as anti-syphon valves.
We always install pressure reducers and filters on drip systems.
We use minimum 18 ga. irrigation control wire.
We install shut off valves before each valve nest.
