Introduction to Water Recycling

Discover how reclaiming and reusing water can sustain our resources and protect the environment.

What is Water Recycling?

Water recycling (also commonly known as water reuse) reclaims water from a variety of sources then treats and reuses it for beneficial purposes such as irrigation, livestock water supply, groundwater replenishment, and environmental restoration.

Why is it Important?

Water recycling can provide alternatives to existing water supplies, reducing surface and groundwater depletion. Source water depletion contributes to decreased water levels of surface water bodies and groundwater resources, water withdrawal cost increase, deterioration of water quality, land subsidence, stressed vegetation and livestock, degradation of wildlife habitat, and negative impact on neighboring water resources.

Benefits of Water Recycling

Water recycling provides sustainable alternatives to traditional supplies, conserving resources and protecting the environment.

Reduces Depletion

  • • Lowers surface & groundwater depletion
  • • Decreases water withdrawal costs
  • • Prevents land subsidence

Improves Quality

  • • Enhances water quality
  • • Improves offsite water quality
  • • Supports soil, air & plant health

Protects Ecosystems

  • • Sustains vegetation & livestock
  • • Preserves wildlife habitats
  • • Minimizes impacts on neighboring resources
  • • Reduces energy use & conserves supplies

The Water Recycling Process

Discover how water is reclaimed, treated, and reused through proven conservation practices to conserve resources and restore ecosystems.

1

Capture & Collect

Harvest water from sources like roof runoff, subsurface drains, irrigation tailwater, and agricultural waste using structures such as gutters, ditches, and catchment systems.

Examples: Roof runoff in Texas, subsurface drains
2

Store & Harvest

Store collected water in reservoirs, tanks, cisterns, or pits for later use, ensuring availability for irrigation, livestock, or environmental needs.

Examples: Irrigation reservoirs in Arkansas, water harvesting catchments
3

Treat & Purify

Apply treatments like denitrifying bioreactors, amendments, or phosphorus removal systems to improve water quality for safe, fit-for-purpose reuse.

Examples: Denitrifying bioreactors, waste separation facilities
4

Reuse & Restore

Distribute treated water for beneficial uses like irrigation, livestock supply, groundwater replenishment, and environmental restoration, reducing depletion and costs.

Examples: Tailwater recovery, recirculated nursery systems in Florida

These steps leverage NRCS Conservation Practice Standards such as 558 Roof Runoff, 436 Irrigation Reservoir, and 447 Tailwater Recovery for sustainable implementation.

Resources

Explore conservation practices and real-world examples for implementing water recycling on your land.

436 Irrigation Reservoir

Store diverted surface water, groundwater, or irrigation tailwater in a dam, pit, or tank for later use or reuse.

Practice Code 436

558 Roof Runoff Structure

Gutters and downspouts collect and convey precipitation runoff from roofs to increase available water for other uses.

Practice Code 558

636 Water Harvesting Catchment

Harvest water from impervious surfaces and store in a tank or cistern for livestock, fish, wildlife, or conservation purposes.

Practice Code 636

447 Tailwater Recovery

Storage and reuse of recoverable irrigation and rainfall runoff, or field drain water to conserve supplies and improve quality.

Practice Code 447

606/607 Subsurface Drain

In-field conduits collect and convey excess water for beneficial use or reuse, improving soil, water, air, and plant relationships.

Practice Codes 606, 607

640 Waterspreading

Surface spreading of runoff over flat areas facilitates groundwater recovery for future reuse.

Practice Code 640

Real-World Examples

Texas Livestock Watering

Rainfall runoff piped from gutters into storage tanks, then gravity-fed to troughs with first-flush diversion for quality.

Arkansas Rice Irrigation

60-acre reservoir captures rainwater and field runoff for rice water needs using side-inlet irrigation.

Florida Nursery Recycling

Evaporative cooling pad excess water drained into troughs, recirculated in tanks—only replenishing evaporation losses.
