Create an Oasis Irrigation system design requires a complete understanding of water pressure and pipe sizing. Before we can begin a design, we start by getting a reading of your static water pressure. The irrigation design is based on a combination of the static pressure, meter size, and service line size. Figuring out these three aspects helps us to come up with the working pressure, which helps us determine the system design capacity GPM (gallon per minute). Meaning you can only have a certain number of heads with a particular nozzle size for each zone, so that you have even pressure. One of the other important aspects during the design phase is making sure there is 100% overlap of the irrigation heads. This makes sure there are no dry spots that are missed.	We are a Hunter and Rainbird preferred contractor, and only use quality Hunter and Rainbird components in our systems. We also include rain sensors that bypass your irrigation system during a rainstorm, and automatic controllers so you never have to think about watering the lawn or flower beds again.
