Selecting
sprinklers, without first researching the information supplied by the earlier
steps in the design process, is premature. Most of the criteria for sprinkler
selection is based on information gathered or calculated in those early
steps.
Selecting
sprinklers
There are a number of types of sprinklers and irrigation devices. Each
sprinkler type has a particular range of applications for which the designer
would specify them.
The main types of equipment are:
Spray
sprinklers
• shrub spray sprinklers
• pop-up spray sprinklers
Rotating sprinklers
• impulse or impact sprinklers
• pop-up gear drive sprinklers
Bubblers and drip irrigation devices
• zero radius or short radius types
• ultra-low volume types
When
selecting the proper sprinklers for a project, a number of factors should be
considered. Some of these factors are:
•
type of sprinklers requested by the owner
•
size and shape of the areas to be watered
•
types of plant material to be irrigated
•
water pressure and flow available
•
local environmental conditions such as wind,temperature, and precipitation
•
soil type and the rate at which it can accept water
•
compatibility of the sprinklers (which can be grouped together)
The
size and shape of the areas to be irrigated often determine what type of
sprinkler will be used. The goal is to select the type of sprinklers that will
cover the area properly using the least number of sprinklers. The type of plant
material to be irrigated can also dictate which type of sprinkler is to be
used. Lawns, shrubs, trees and ground covers may all require different types of
sprinklers.
