Water intake screens are considered the first safeguard of the intake system, keeping fish safe and pumps and turbines protected from harmful debris. They are both efficient and environmentally friendly.


  • It is an passive device with no moving parts, allowing efficient and effective fabrication with little to no maintenance.
  • The continuous slots and large open area are the minimum clogging and maximum water flow.
  • Various designs and configurations accommodate deep to shallow depths.
  • The stainless-steel material is corrosion-resistant and long-lasting.
  • It protects aquatic life and also protects pumps and equipment safe from harmful debris.
