An AWMA Self-cleaning Intake screen was installed west of Dubbo, NSW.
The property owners understood the need for fish friendly irrigation pump stations. They also wished to support the ‘Best Practice’ guidelines for Fish-Friendly water extraction initiatives.
Installation of the AWMA Intake Screen not only protects the fish population in his local river, but also protects his pump equipment.
With an in-built, self-cleaning function, restricted flow rates due to weed and debris blockages are no longer an issue.
The self-cleaning intake screen is a single cylinder screen manufactured from stainless steel wedge wire with an innovative dual brush system.
The screen was retrofitted to the existing track system to allow easy installation, inspection, management and maintenance, should it be required.
To facilitate simple, economical cleaning of the screen, this AWMA Screen is a self-propelled version. The self-propelled screen utilises a propeller drive system to operate the self-cleaning function automatically, whenever the flow in the suction pipe exceeds a certain velocity. This in turn rotates the screen through a gearbox arrangement to self-clean the cylinder screen, keeping the wedge wire surface free of algae, weed and debris. This feature ensures the delivery of required irrigation flows while preventing fish impingement and entrainment.
