Feasibility Study and Master Planning

There are 3 steps to successful irrigation projects:

  • Step 1: Quick feasibility and master plan study.
  • Step 2: If found feasible, start engineering and design. 
  • Step 3: Tendering, Construction and Project Management.

With over 2000 irrigation systems designed in our over 40 years of consulting, IRZ’s expertise and engineering are unmatched. Our team of engineers design the right solutions, and we take pride in providing a full range of services that bring superior results. IRZ possesses both the experience and the skill to design and construct large-scale and modern irrigation systems. Our success is established in our extensive real-world experience in irrigation design and construction,  and our in-depth knowledge of irrigation engineering technologies. Our clients range from medium to large farms to governments across the world; no matter the size, IRZ can assist every step of the way to custom-fit your irrigation solution. 

It all begins in the feasibility stage, where we send an engineer to the site, to assess your land, water and agricultural vision. We take into consideration all aspects of soil, power and water resources to find an economic solution. We consider everything from the development of surface water or groundwater, the land topography, climate and environmental considerations. Our water-right experts research permitting to ensure projects adhere to applicable governmental policy. 

Our mission for water conservation drives us to find sustainable solutions that benefit both growers and the environment, such as on-farm water management projects. IRZ considers every detail. This meticulous work results in a comprehensive report, with estimated cost (CAPEX/OPEX), timeline, and recommendations that best inform our clients of all their options for development.

Irrigation Engineering and Design

After approval of the feasibility study, the next step is engineering design phase. Our registered professional engineers (PE) design each component with care and attentiveness. IRZ’s expertise ensures we evaluate all the logistics to build a state-of-the-art system that provides excellent service and efficient operation for years to come. We design the complete irrigation system which may include:

  • Pumping and inline booster stations
  • Intake structures, valves, screening and filtration system
  • Large mainline networks
  • Canal and drainage design
  • Groundwater well development
  • Reservoirs
  • Remote monitoring and control systems 

Once we’ve completed the initial design, we use advanced hydraulic modeling software to test for proof of concept. Our models take into account the full network and can adjust pipe sizing, water flow speed, pressurization, elevation changes, and pump lift. This technology maps out many alternatives and scenarios to find your optimal system design. We’ll bring you a design that’s tested, precise, and custom-fitted for your needs.

Our design approach can also account for future demands of an irrigation system in the event you later expand.

Our decades of proven success is a result of our engineers putting their designs under multiple peer review, ensuring IRZ provides high-quality services. We double and triple-check every project before putting our final seal of approval, and we pride ourselves on superior quality control and fastidious attention to detail.


Irrigation System Efficiency

IRZ’s services don’t end when your irrigation construction does. Even after completing each project, IRZ comes alongside our growers to continue providing excellent maintenance and insuring top efficiency. We help our clients prepare for upcoming growing seasons by testing different irrigation scenarios in our highly advanced hydraulic modeling software. This helps us catch any efficiency issues before they arise.  In one instance, IRZ’s quality assurance investigation discovered a worn pump that was consuming power but failed to meet the pressure requirement.

To test your irrigation system efficiency, we use state-of-the-art ultrasonic flow meters, which measure flow rates without the pump being shut off. We take diagnostic electrical measurements to account for voltage, amperage, and power factor. A comprehensive report determines the efficiency of existing systems and makes recommendations to improve efficiency and reduce costs.

IRZ is a recognized leader in water and energy conservation and resource management in irrigation. We’ve received awards for our innovative approaches to water conservation, such as our aquifer restoration technologies that allow growers to store and recover declining groundwater through surface water in high flow periods. 

IRZ also implements designs and technologies to maximize energy savings. The US Secretary of Energy granted IRZ an award for our irrigation energy conservation technologies. We’ve conducted hundreds of energy-efficient designs and modifications across the United States, yielding savings ranging from 20-50% in energy costs.
