Wedge Wire Screens for Agricultural Irrigation

Agricultural irrigation systems pump water from rivers, canals, reservoirs, and groundwater sources — all of which carry sediment, organic debris, fish, and aquatic vegetation that damage drip emitters, sprinklers, and pump impellers. Wedge wire intake screens and self-cleaning Coanda screens provide fish-safe, low-maintenance pre-filtration that protects downstream irrigation infrastructure. The continuous V-slot resists clogging from algae and silt, and passive intake configurations meet environmental standards for fish protection in surface water diversions.

APPLICATIONS

Where Our Screens Work

Surface Water Intake

Coanda screens and T-screen intakes for canal, river, and reservoir water diversion. Fish-friendly, self-cleaning, no power required — ideal for remote irrigation districts.

Drip Irrigation Pre-filtration

Cylindrical strainers upstream of drip emitter networks. Slot size matched to emitter clearance prevents clogging and extends emitter life across thousands of irrigation cycles.

Pivot and Sprinkler Systems

Inline filtration for center-pivot and lateral-move irrigation. Protects nozzles, regulators, and end-guns from sediment, fiber, and algae carryover.

Groundwater Well Screens

Borehole screens for irrigation wells. Engineered for collapse strength under aquifer pressure and matched to formation grain size for sand-free water delivery.

Agricultural Drainage and Effluent

Sieve bend and rotary screens for tail-water recovery, agricultural runoff capture, and effluent screening before discharge or recycling.

Greenhouse and Hydroponic Systems

Fine-slot filtration for nutrient solutions and recirculating greenhouse water. Stainless steel construction tolerates fertigation chemistry without corrosion.

FAILURE MODES & MITIGATION

How Screens Fail — and How We Prevent It

Algae and biofilm blinding

V-wire continuous-slot geometry releases biofilm and stringy algae during natural flow events. Coanda screens stay self-cleaning over multi-season service.

Sediment and silt buildup

Coanda acceleration plate maintains sweep velocity over the screen face; T-screen submerged intakes use low through-slot velocity to limit silt entrainment.

Frost and ice damage

Stainless steel construction tolerates freeze-thaw cycles; drain provisions and angled geometry reduce ice anchor points in cold-climate canals.

Pump cavitation from undersized intake

Screen area sized to design flow with safety factor; through-slot velocity kept low to avoid head loss spikes and pump starvation.
