In order to get the best irrigation design in Yelm, WA, your certified irrigation systems contractor will need to pay close attention to eight core facets of the sprinkler system, each serving a critical purpose in the overall function of the system. Let’s take a look at all eight parts and why they’re so very important to the entire system:
- Sprinkler spacing
Sprinklers come in a wide variety of shapes, sizes, and installation options. Contractors will space them out so that their throw radius does not overlap, and choose the best type taking into account possible growth of plants and other vegetation in the area. They will also consider safety issues: for example, a pop-up sprinkler may incur vandalism or be a tripping hazard in the wrong environment.
You may be surprised to hear that there are specific regulations for irrigation system pipes. But these rules will benefit you in the long run. For example, a good piping structure will be able to compensate for elevation and pressure changes. It will also be strong and flexible enough to withstand extreme weather conditions and erosion.
Sprinklers that are placed together are in a ‘zone.’ Each zone is required to have the same amount of water precipitated, which means your lawn will not be soggy in one spot and parched in another. Some areas of a yard may require more or less water in order to be consistent with the rest of your landscaping, and your contractor will take this into account, and identify these spots as separate zones.
- Controller regulations
There are many components of each irrigation system, and they must all be up to spec. Controllers, which automatically start and stop sprinkler systems, for example, are closely scrutinized to ensure that they are economical and meet all of the zone requirements for pressure, flow, and economy.
- Pressure control
There are also specific rules for pressure. This is because drastically low pressure, high pressure or fluctuating pressure can lead to damaged systems, excessive utility costs, ruined yards, and more. A good system will have adequate pressure regulation for each area, and if necessary, will have items that compensate for pressure to keep it level.
- Winter care
Irrigation systems are a permanent and valuable investment, and thus are not meant to be taken out when cold weather hits. Therefore, each system is required to have components that can withstand freezing temperatures, as well as a good way of draining water out of the system so it doesn’t freeze inside pipes or heads.
- Zoning for low volume/micro irrigation
Sometimes low volume irrigation is necessary, and when this is the case, it will be zoned separately. It will also have its own system, not attached to the main spray heads or rotors.
- Proper control wire
Control wire will be sized and utilized according to its zone, and according to manufacturer instructions.
If you have questions about irrigation design in Yelm, WA, speak with your irrigation contractor so he/she can explain the separate facets of a sprinkler system to you and the role each component plays in the overall function of the system.
