About Us

What excites us is designing amazing irrigation systems, quick and efficient installation and happy, satisfied customers. That’s how RWE operates. We do it well the first time, and we’re passionate about what we do.

Formed in 2006 and previously known as Riverina Water Engineering, RWE Yenda Prods Irrigation (RWE) is a collaboration between Yenda Producers Co-operative and Jak Ormesher. For over a decade we have expanded to become a major irrigation company within the region and gained recognition for introducing new technology and practices to the water industry.

Our large, experienced team covers every aspect of irrigation – design, engineering, programming, training, project management, retail, service and audits. What’s important to us is working with each client to reach a solution that fits their budget, meets deadlines and above all provide original turnkey solutions. Regardless of the scale, we enjoy working with clients who think collaboratively and outside the square.

As champions of innovation, RWE uses the latest products and technology and offer a range of in-house manufacturing options and partner with trusted suppliers. We understand the need to incorporate systems that work best for your operation and deliver the highest efficiency and return on dollars invested. When what you need is passion + a comprehensive irrigation approach, contact the team at RWE.
