Sizing an intake screen depends upon water withdrawal rate
(in gpm or cfs) and screen open area. Screen open area is based on wire size and slot opening.

Norris offers a wide range of screen configurations, tailored to your needs. If backwashing or air bursts are needed, we can build to your specifications.

Norris intake screens are fish friendly and offer low risk of impingement during operation. For more information print and fill out the data sheet below. There are four versions for your convenience
