WIP - Water Intake Fish Protection Screen

Beaudrey WIP

**Named BTA for 316(b)**

Background

For the past 35 years, Beaudrey has been actively pursuing effective engineering solutions for fish and other marine life protection. The goal is to help power plants meet the EPA standards for fish protection without sacrificing plant efficiency or raising their capital and operational expenditures. This dedication to researching, designing and engineering Fish Protection Systems has produced several groundbreaking systems:  the Beaudrey Scoop-a-Fish™, Bio-Flush™ System and NoCling™ mesh panels.  

The most recent addition to the Fish Protection System portfolio is the Water Intake Protection Screen (WIP). This water screen is a highly effective solution to reducing fish mortality caused by impingement and eliminating entrainment during water screening.

The WIP Screen has been so successful that is has been named as best technology available for 316(b) compliance.

Overview How it Works Value Creating Advantages

Overview

The Water Intake Protection Screen (WIP) was developed as an alternative to traditional thru-flow traveling band screens and can be retrofitted into existing band screen openings. Additionally, the WIP can be fitted to existing intake structure configurations and its innovative design eliminates debris carrryover, fish impingement, and fish entrainment problems that are seen with traditional coarse mesh traveling band screens. The WIP underwent a rigorous study at the North Omaha Power Station located on the Missouri river to assess its affect on the mortality rate of fish that may be impinged or entrained on the screen. The study showed that fish impinged, removed, and recovered from the WIP exhibited survival rates that were no different from those observed for the controls, suggesting that the screen did not contribute to any observed fish mortality during the study. Additionally, the study concluded that the WIP can be considered as an alternative technology under section 316(b) of the Clean Water Act. The full results of the study were published in the North American Journal of Fisheries Management.
