Passive Intake Systems

Intakes for drinking water plants, desalination plants, power plant cooling systems, irrigation water, potable water and many other applications require careful design considerations in order to responsibly protect aquatic life at the intake.
Meticulous design and construction yields durable sub-surface intakes with minimal operating and maintenance costs.
The Johnson Screens® passive intake design is based on a submerged wedge-wire (Vee-Wire® cylinder) cleaned by the Hydroburst™ air-backwash system, which was developed by our company and is EPA 316b-compliant (the through-screen velocity can be designed below 0.5 fps to minimize entrainment. This system offers many benefits. 

  • Low cost
  • Limited maintenance
  • Environmentally friendly
  • Easy cleaning
  • No disposal of debris
  • Customized design
  • Adaptability
  • Efficient wedge-wire/Vee-Wire® filtration
