How it works

Treats water through substrates, microorganisms and vegetation in dimensioned and supervised systems.

It applies the hierarchy of understanding, avoiding, reducing, reusing and treating, always maintaining the right quality for each use and health protection.

When does it make sense?

  • With a water balance and significant uses
  • When regulation and health risk allow the solution
  • With clear inspection, treatment and maintenance officers

How to apply it

  1. 1

    Defining what need resolves "constructed wetlands and ecological purification" and establishing a starting situation.

  2. 2

    Compare alternatives and adapt design to climate, use, regulation, affected people and available resources.

  3. 3

    Apply with clear responsibilities, check the actual result and correct unwanted effects.

Potential benefits

Reduced demand for drinking water

Less spills and runoff

Increased water resilience

Limitations and precautions

  • The result depends on context, design, execution and how it is used and maintained.
  • Saving water never justifies compromising hygiene or quality.
  • Alternative systems need signage, secure networks, maintenance and risk control.
