A case study... Hydrometers


Miscellaneous
LIKE MOST COLLEGES around the country, the 1,700-acre University of Utah campus in Salt Lake City is constantly building new labs and classrooms, new sports facilities, etc. With ongoing campus construction and irrigation components that date back 50 years, there’s no end to accidentally broken lines or leaky valves.   More

Pumps and Pump Stations


Irrigation
The same is true of many irrigation systems. In the past, irrigation designers and contractors may have been able to design and build systems that didn’t need an extra boost from one or more pumps, because plenty of pressure came out of the municipal water system.   More

Simple Fix for That Problem Watering Zone


Miscellaneous
Its green now, but the far area of my backyard used to be brown, spotted and ugly. This was because my expanded landscape had too many sprinklers, and the only pipe to the area turned out to be too small to supply the needed water.    More

Filters in the Landscape: Maintaining Irrigation Design Integrity

filtration


Miscellaneous
The continued emphasis on water control and conservation is contributing to the downsizing of irrigation emission devices, like drip or microspray irrigation, which provide pinpoint applications at very low rates.    More

Cross Connection: an unprotected connection point between a drinking water source and any source of nonpotable water.


Irrigation
A cross connection is defined as an unprotected connection point between a drinking water source and any source of nonpotable water. If a cross-connection point is not protected, it is possible for the flow of water to reverse its direction.    More

Backflow Prevention: Protecting Water, Protecting Yourself


Backflow
For potable water, life is a series of one-way streets. Safe drinking water depends on all “traffic” within a water system to move in the direction it’s supposed to. Fresh water flows one way. It isn’t supposed to turn around and travel in the other direction.    More

Don't Let the Irrigation Business Scare You


Miscellaneous
If you’ve never worked on irrigation before, upon close inspection an irrigation system might appear to be a jumble of wires running here, there and everywhere, valves that work in a way you don’t understand, and pipe running underground.    More

Irrigation Wire: The Landscape's Central Nervous System


Irrigation
As manual irrigation control has been replaced by automatic control, communication between the automatic control device and the valves has become critical to the integrity of any automatic system. Like the nerves that carry impulses between neurons and the brain. If the message is corrupted between the two, so will be the resulting response.   More

Balancing System Hydraulics: Pressure for Performance


Irrigation
Perhaps the most overlooked problem with landscape irrigation system performance is pressure. A healthy balance of pressure is good for the performance and longevity of your irrigation system, and thus the aesthetics of your landscape. Keeping some fundamental hydraulics in mind, minimizing the impacts of too much or too little pressure in an irrigation system is simple, quick and effective.    More

Irrigation Piping Materials: Past & Present


Irrigation
The conclusion of World War II marked the introduction of new technologies to private industry that were developed for the war effort. One that would certainly revolutionize the residential/commercial marker of the irrigation industry was thermoplastic pipe.    More
