Install Low-Pressure Sprinklers and Slash Costs

Monday, July 25, 2016

Low-pressure irrigation systems like those from Senninger have provided significant savings in energy and water costs. These systems use low-pressure sprinklers designed to operate between 10 psi and 25 psi (0.7 bar and 1.7 bar).  They reduce pumping demands without significantly reducing flow, so crops continue to receive a healthy amount of water.

Senninger low-pressure sprinklers further reduce energy usage by irrigating more zones at the same time.  Another advantage is that low-pressure sprinklers irrigate with larger droplets, which are more resistant to wind and evaporation.

Senninger’s Wobblers apply water instantaneously in a large 360° wetted pattern, which translates into lower application intensity. This helps maintain the soil’s infiltration capabilities and prevents surface compaction and run-off.  With Senninger’s Wobblers, farmers can expect to see an energy saving of up to 50%.


Low-pressure sprinklers save water and money

Irrigation is one of the main consumers of energy on a farm. Most irrigation systems still use high-pressure impact sprinklers that release an enormous volume of water using pressures between 40 psi and 75 psi (2.7 bar and 5.2 bar). Modifying irrigation practices and adopting new low-energy technology is becoming ever more important to ensure profits.

Before reducing pressures and pump sizes, be sure that the new sprinklers are specifically designed for low-pressure operations. The criteria for low pressure may vary from one manufacturer to another, but most agree that anything over 30 psi is a mid-range to high-range sprinkler.
