The Trangie-Nevertire Irrigation Scheme (TNIS) screening project is Australia’s largest showcase of modern pump screening designed for fish protection.

Located on the Macquarie River NSW, TNIS is a member-owned organisation managing 100,000 hectares of mixed farming enterprises and supporting almost 21,450 hectares of irrigation.

In 2020, with the support of NSW DPI and DPIE Biodiversity & Conservation Division and leading irrigation engineers, TNIS on the Macquarie River upgraded their current intake trash racks with four automated, self-cleaning cone screens so they meet fish protection guidelines. By using 3mm wedgewire and creating low velocities at the intake, TNIS will be able to deliver water to its members that is free of fish and debris. The current screens protect four axial pumps capable of diverting up to 715 ML per day from the Macquarie River.



Main pump June 2020, stock and domestic coming late 2020

AWMA Water Control Solutions

Project Partners:

NSW Department of Industry and Environment (EES), Department of Regional NSW (Fisheries), Trangie-Nevertire Irrigation Scheme and AWMA Water Control Solutions, Recreational Fishing Trust and OzFish Unlimited.

Project Funding:

The main pump screen was funded by revenue generated in the 2018 sale of environmental water via the NSW Drought Relief Fund. The stock and domestic pump screen was funded by an NSW Recreational Fishing Trust Habitat Action Grant.



The major intake pump at the Trangie to Nevertire Irrigation Scheme is being screened.(ABC Western Plains: Jessie Davies) Every year 100 million fish are killed by irrigation pumps throughout the Murray Darling Basin — but a simple solution could stop the carnage. Key Points: A single large river pump can kill as many as 12,000 fish a day on the Murray-Darling The deaths negatively impact the environment and irrigators, who are forced to deal with the mess There are calls for screens that prevent the problem to be installed on all irrigation pumps A fish exclusion screen acts as a physical barrier to stop fish being sucked into large pipes and macerated. For the first time in New South Wales, a large screen is being installed on a major pump that feeds 33 farms from the Macquarie River, near Trangie. NSW Department of Primary Industries research scientist Craig Boys said the installation would save hundreds of fish a day.

19 JUNE 2020 | FISH ARE FRIENDS: Brand new irrigation screening aiming to protect millions of fish a year

$500,000 worth of funding will be used to set up irrigation pipeline screens set to benefit irrigators, environmental groups and recreational fishers as well as endangered fish in the region's waterways. The project, which has taken decades to progress to this stage, will erect fish screens over irrigation pipelines that exist along the Murray Darling waterway and is currently constructing fish screens for irrigators in the Trangie and Nevertire areas to benefit from. Senior Fisheries Manager Sam Davis says the project could potentially save millions of fish from being extracted and in many cases destroyed from the region's water. "Fish screens prevent fish from being entrained into our pump irrigation and our water channels," Ms Davis said. "Those fish who are extracted are completely lost to the local ecosystem, they will never get to return, we lose all their genetic input and we can't get it back." "Our scientists have worked at quantifying how many fish are lost, and at our best estimate, millions of fish are lost in these water systems every year."
