Clearwater Suction Screen
Compliance Through Robust Engineering & Biological Safety
The "Double Safety" Factor
While federal regulations allow higher velocities for active screens, the Clearwater design conservatively operates near the "Passive Limit." This ensures even weak swimming fry can easily escape.
✅ Safe for fry & juvenile fish
NMFS Compliant
- • Mesh: 12-Mesh Stainless (Smaller than 3/32" limit)
- • Cleaning: Continuous (Exceeds 5 min rule)
- • Porosity: ~40-50% Open Area
Operational Benefits
Zero-Power Operation
Driven entirely by water pressure. No electric motors, gearboxes, or solar panels required.
No External Moving Parts
Mechanisms are sealed inside. No chains or sprockets to freeze or jam with driftwood.
Universal Installation
Sealed bearings allow mounting at any angle (vertical, horizontal, inclined) for any riverbank.
Self-Protecting
Prevents pump cavitation and wear, extending the life of expensive infrastructure.
The "Set It and Forget It" Solution
The standard Clearwater design meets regulatory requirements not by adding complexity, but by utilizing superior surface area ratios. It protects your water rights and the fishery with equal effectiveness.
