AWMA has delivered low-flow, water-driven, self-cleaning intake screens to support a remote irrigation system in New Zealand’s Canterbury High Country.
These screens play a critical role in providing clean, reliable water for irrigation, livestock, and homestead use. The property operates under seasonal water consents, requiring flexibility in water extraction throughout the year. To meet site requirements, AWMA supplied a self-cleaning, water-driven intake screen, two years ago, with another scheduled for installation later this year.
Mounted on a ‘Hockey Stick’ arm with a hand winch, this retrieval manual design enhances operational flexibility, allowing operators to easily raise and lower the screen for inspection or maintenance if required.
As part of AWMA’s commitment to continued client support, a recent site visit was conducted in collaboration with consulting engineers, Matai Consultants, to review screen performance, assess installation quality, and ensure ongoing operational functionality. Part of a broader intake system upgrade that includes a fish bypass and additional water delivery infrastructure the visit also assisted in planning for the second screen installation.
The site’s challenging conditions include frequent flood events and snow-fed waterways that result in the presence of an extremely fine glacial sediment. AWMA partnered with local consultants and landowners to work through these issues, resulting in successful outcomes. The visit reinforced the importance of collaborative problem-solving, hands-on support, and robust designs to achieve successful, long-term results.
With the system operational and delivering clean, screened water, the project reflects AWMA’s commitment to delivering fit-for-purpose, sustainable infrastructure that assists clients within irrigation-based industries achieve environmental compliance as well as sustainable water management systems.
