Hendrick Screen has 30 years of experience and technical expertise in the production of stainless steel screens.

We are a leading producer of passive water intake screens used for the withdrawal of large volumes of water from streams, lakes and reservoirs.

Hendrick fish diversion screens are used in dam and river systems throughout North America to protect fish from hydroelectric turbines. Our screens comply with NMFS standards and they are specified by the U.S. Department of Fish and Wildlife dept., Corp of Engineers and many State Departments of Fish and Wildlife Depts. for the protection of fish.

What Is Passive Screening?

Passive screening admits water through the intake point at a low, uniform velocity. Water passes through the intake screen slots while aquatic life and debris remain in the water source. The intake screens have no moving parts, therefore the term "passive screening". They can be placed away from shore for better water quality and distant from high concentrations of debris and marine life.

Advantages Of Passive Screening

• Reliable water delivery
• Lower screen system costs
• Simpler intake and pump station design
• Lower total project costs
• Lower maintenance costs (No moving parts, no trash screens to clean, no on-land debris to handle, and no drive mechanisms to break down.)
• Small fouling material stays out of the pumping system
• Environmentally friendly to fish and other aquatic life
