Water intake systems using traditional travelling band screens are often faced with the problem of debris carry-over and marine life mortality as a result of fish impingement and entrainment on the screen.


They are not well suited for water-life recovery and return and often these screens can be difficult to retrofit with fish-saving technologies.


The BEAUDREY WIP screen (Water Intake Protection) has been developed to overcome these problems and can be considered an alternative technology to traditional travelling band screens; it can be retrofitted into existing thru-flow screen pits. Its design is a combination of the time-tested “Scoop-a-fishTM” system and the revolutionary BEAUDREY Debris Filter resulting in a unique, reliable and high-performing screen.


The WIP’s design allows for simple installation into existing thru-flowing travelling band screens guides. After an existing thru-flow screen is dismantled and removed from the pit, the modular WIP can be slid into the pit within a day. No modification of the concrete structure is required.

WIP screens can also be retrofitted in most existing screening plants with any other type of machines.


As the water flows through the circular screening element, marine species are arrested by the fish-friendly NOCLING™ panel. Fish are then kept in deep compartments located on the upstream face of the NOCLING™ panel. Within one minute, they are removed by a fish-friendly scoop and pump into a returning flume. From here they are redirected by a pipeline around the water screen and into the outlet water. The fish are never exposed to the high or negative pressures and temperatures of the power plant, nor do they ever leave the water, so they are never exposed to air.

Reverse rotation prevents jamming by large debris.

  • Rated by EPRI as the best available fish and intake screen technology

  • Well suited for water life: a two-year, independent study confirmed that the WIP has no negative impact on marine life

  • Helps plants to achieve EPA 316(b) requirements

  • Proven lowest fish mortality rate of intake systems (EPRI)

  • Fully customizable

  • No debris carry-over

  • Resistant to high H2O pressure differentials

  • Design to retrofit existing travelling band screens as well as for new plants

  • Easy installation: no modification of concrete structures is required

  • Installed with NOCLING™ anti-fiber screening panels for water with high fibrous content (screening sieve available)

  • Easy to operate and maintain; all equipment can be lifted out of the water in three hours or less for inspection.

  • Fewer moving parts than a traditional travelling band screen allows for easier, less frequent and lower-cost maintenance

  • Based on the design principle of the BEAUDREY “W” filter, allowing for spare part interchangeability with the BEAUDREY Zero Ball Loss (ZBL™) condenser tube-cleaning system and the BEAUDREY debris filter

  • Slid into wall guides, it can easily be lifted out for maintenance without dewatering the pit.

WIP screens exist for all flow rates usually found in screening plants.

When any WIP2 is too small for the application, the WIP3 range provides the required higher flow rate solution.

Mesh apertures range from 6mm down to 1mm, as required.
