Post-Flood Irrigation Filtration & Dirty Water

Floods and atmospheric rivers leave irrigation water dirtier for seasons to come. Here's how to protect your filters, pumps, and emitters before next year's water turns on.

Floods Don't Just Hit the Field — They Change Your Water Source

When rivers, canals, and ditches flood across farmland, they pick up everything in their path—soil, sand, organics, manure, fertilizers, and debris. Once waters recede, a lot of that material settles into:

  • River and canal beds
  • Farm ponds and reservoirs
  • Sumps, forebays, and pump bays

The result is irrigation water that is:

  • Heavier in sediment and turbidity – more silt and fine sand to plug screens and filters
  • Loaded with organics and nutrients – a recipe for algae and biofilm when temperatures rise
  • Carrying more trash and debris – sticks, leaves, plastics, and crop residue at intakes

You may not feel all of it today—but when you start up irrigation in spring, your suction screens, filters, and emitters will.

What Growers See After a Big Flood Year

Suction screens on rivers and canals plugging more often

Filters going from "weekly rinse" to "daily or multiple-times-a-day"

Higher pressure loss across filters even when they appear clean

Emitters and nozzles plugging sooner in the season

If you had marginal filtration before, flood-driven dirty water will push it over the edge. The good news: the off-season is the best time to inspect, clean, and upgrade before you're fighting problems in the heat of irrigation season.

Filtration & Intake Protection for Flood-Impacted Irrigation Systems

Self-Cleaning Suction Screens

  • Protect pumps pulling from rivers, canals, and ponds
  • Continuously shed debris so crews aren't living at the intake location
  • Reduce the number of sticks, leaves, and larger debris getting to your filters

Inline Filters Built for Ugly Water

  • Automated brush & vacuum inline filters to remove sediment and organics before your drip or micros
  • Stainless and economy lines sized for higher sediment loading
  • Configurable in parallel for systems that have outgrown their old capacity
Explore inline filtration systems

Our team can review your current suction screen and filter configuration, then recommend adjustments tailored to the dirtier water conditions you'll see after major flood years.

Use the Off-Season to Get Ahead of Next Season's Water

1

Inspect Intakes & Screens

Pull and inspect suction screens, pump intakes, and pond inlets. Look for dents, coating loss, heavy fouling, and signs of bypassing.

2

Open Up Filters and Look Inside

Don't just backflush—open housings, inspect screens/elements, and check for accumulated fines and damage.

3

Right-Size Filtration for Flood-Driven Loads

If you were barely keeping up before, this is the time to increase screen area, add self-cleaning, or add a pre-filter stage.

Even a simple inspection and small upgrade now can save you hundreds of labor hours and thousands in crop damage later.

Talk Through Your Irrigation Water & Filtration After the Floods

Whether you farm in the Yakima Valley, the Skagit and Snohomish valleys, or another flood-prone region, the principles are the same: flood years change how hard your intakes and filters have to work.

If you're not sure how to size or configure filtration for the next few seasons of dirty water, we're happy to talk it through and offer practical options.
