RESIDENTIAL IRRIGATION SYSTEMS Greenland Irrigation started as an installer of residential irrigation equipment and we have never lost sight of our primary customer, you the homeowner. All of our installers and service technicians are thoroughly trained on all aspects of the residential sprinkler installation.  It is very important that your system be installed properly the first time to ensure proper watering and to prevent future repair and maintenance issues down the road.
BRANDS OF EQUIPMENT The primary brands of irrigation equipment are:
Each Manufacturer offers a complete line of timers, valves and sprinkler heads. There are slight differences between the brands. As the experts, we would be more than happy to show you the differences between the brands and recommended the best products to use. We tend to use only the best components from each manufacturer to reduce the frequency of service calls.
WARRANTY Greenland provides an unconditional "5 year warranty " as long as the system is serviced by Greenland each year. Vandalism is not covered by warranty and the standard manufacturers warranty is only 1 year.
CUSTOM DESIGN During the estimation period, we begin by meeting at your home to evaluate the property to design a system tailored to your landscape needs. We take a pressure reading to determine your water pressure and we inspect the interior plumbing to determine your water flow rate "gallons per minute". A comprehensive layout of the property is completed on design paper, showing the exact location of all sprinkler heads, valves and piping. Areas of the lawn and garden are then sectioned into zones for customized watering.
SPRINKLER HEADS There a two types of sprinkler heads available to the consumer and they are:
1. Rotor Heads	2. Spray Heads
The sprinkler heads are the most important product since they are the only moving parts. Rotor Heads are often used to cover large turf areas spraying between 25 and 30 feet. Spray Heads are more often used to cover small garden and lawn areas. The spray distance for a fixed pattern Spray Head is a maximum of 15 feet and can be adjusted to spray 5 feet if necessary. Spray Heads are more often used to cover gardens and small turf areas
THE CONTROLLER
	The Controller is the "computer" which operates the watering schedule for the irrigation system. It can be programmed to run odd or even days, by days of the week, or by interval days. The Controller can be installed in your basement or preferably in the garage for easy access. Hand held remote controls are a new product now available for the controller.
CONTROL VALVES
	The Control Valve or Solenoid Valve is merely an on-off switch for each sprinkler circuit. The Control Valves are located in the lawn usually inside a green box. The Controller is connected to the Control valve via direct burial wire.
PUMP SYSTEMS Water for the irrigation system can also be supplied by submersible pump (below groundl) or by centrifugal pump (above ground suction pump ). For wells, it is important that the "replenishment rate" for the well be determined before the system in designed. The irrigation system must not exceed the replenishment rate for the well. The recommended pump size for an irrigation system would be at least ½ horse for a small lot. A three-quarter or one horse pump would be most desirable for a residential application for up to ½ Acre in size. Properties larger than an acre may require a larger pump and in some cases up to 5 horse power. Greenland will work in conjunction with the pump supplier to ensure adequate pressure and flow.
