ANTAEngineering & Infrastructure

Define required quality, treatment barriers, verification and risk.

This resource explains the principle, key decisions, common mistakes and the data required to go further.

Water

Key points to retain.

Reusing treated water starts with end use and exposure pathways. Treatment, storage, distribution and verification together form the sanitary barrier.

  • Quality suitable for irrigation is not automatically suitable for cleaning or process use.
  • Storage can degrade well-treated water.
  • Reuse pipework should be identified and separated from potable water.

Guided reading

Understand the mechanism, then its consequences.

01

Define use

Who or what is exposed through contact, aerosols, indirect ingestion or infiltration?

02

Set criteria

Microbiological, chemical and operational parameters follow risk and local rules.

03

Design barriers

Treatment, disinfection, storage, network, access restriction and operating practice work together.

04

Monitor

Continuous measurements, sampling, alarms, deviation action and records protect operation.

Prepare a study

Useful data before reaching a conclusion.

The visitor can begin with these items. ANTA will then determine which measurements and checks are really required.

  • Source and quality
  • Precise final use
  • People exposed
  • Volume and seasonality
  • National rules
  • Control plan and fallback

Frequently asked questions

Clear answers without oversimplifying.

01Is clear water safe?

Clarity does not reveal all microorganisms or dissolved contaminants.

02Can food crops be irrigated?

It depends on quality, irrigation method, edible part, time to harvest and regulation.

03Why is a fallback needed?

To stop or divert use when quality or control is lost.

Essential glossary

Use the right words for the right decisions.

Reuse
Planned new use of treated water.
Exposure
Pathway by which a person or environment meets a hazard.
Disinfection
Targeted reduction of microorganisms.
Separate network
Distinct, identified pipework preventing cross-connection.
