UAE Water Quality Regulations 2025: Full Breakdown with Laws, Limits & Stakeholder Responsibilities

WATER QUALITY REGULATIONS 2025 08 April 25

As of January 1, 2025, the Abu Dhabi Department of Energy (DoE) officially implemented the Water Quality Regulations 2025. This sixth edition reflects global standards while emphasizing local challenges—especially in the face of climate stress and rapid urban growth.

These regulations are legally binding for residential, commercial, and industrial users, requiring stricter monitoring, reporting, and compliance throughout the water supply chain.

LEGAL BASIS

Law No. (11) of 2018
Concerning the Establishment of the Department of Energy in Abu Dhabi

Article 4: Grants the DoE authority to regulate water quality, enforce compliance, and issue penalties across all sectors—public and private.

Sample Parameters – Schedule 1 (Drinking Water Standards)

ParameterLimit ValueCategory

pH6.5 – 8.5Physical
Free Residual Chlorine0.2 – 0.5 mg/LChemical
Total Coliforms0 CFU/100 mLMicrobiological
Nitrate (NO3)< 50 mg/LChemical
Lead (Pb)< 0.01 mg/LHeavy Metal
PFAS (Emerging Contaminant)< 0.0001 mg/LEmerging Pollutant

Clause 6.3: Exceeding any parameter mandates urgent reporting to DoE and corrective action within 24 hours.

Who Is Affected? Residential & Commercial Users

The regulation is not only for water producers or government utilities—it directly affects residential buildings, commercial towers, hotels, hospitals, shopping malls, and schools:

For Commercial Users:

  • Building managers must install and maintain proper filtration systems.
  • Quarterly water testing reports are required for large buildings and complexes.
  • Cooling towers, water tanks, and fountains must be included in the DWSP.

For Residential Compounds & Villas:

Landlords and facility managers must ensure water storage tanks are cleaned, sealed, and tested regularly.

Tenants have the right to request water quality certificates from landlords or developers.

Clause 5.2.4: All premises with storage/distribution responsibility are deemed “licensees” and must meet quality and safety requirements under DoE oversight.

 Chemicals in Drinking Water

Clause 6.1.3:

“Water treatment must only involve chemicals that are officially approved by the Department of Energy (DoE), proven safe for human use, and certified by recognized third-party bodies such as NSF or WHO.”

Unapproved chemicals = automatic violation, regardless of perceived safety.

Sampling Frequency (Distribution Zones – Schedule 3)

Zone PopulationMicrobial TestingChemical Testing
> 100,000WeeklyMonthly
10,000 – 100,000BiweeklyQuarterly
< 10,000MonthlyEvery 6 Months

Sample collection must follow international best practices, including sterilized containers, documented chain of custody, and digital recordkeeping.

Drinking Water Safety Plan (DWSP)

All water providers (including commercial properties and residential complexes with their own storage or treatment systems) must develop and submit a Drinking Water Safety Plan, which must include:

  • Hazard mapping and risk management
  • Maintenance of tanks and plumbing
  • Emergency protocols (e.g., contamination or low pressure)
  • Ongoing staff training and corrective tracking

Clause 7.1.1: Annual DWSP audits are required, and major updates must be reported within 10 working days.

Audits and Assessments

Clause 8.4:

“Independent audits shall be conducted every two years for all licensed water operators, including residential developments with internal water systems.”

Audits assess:

  • Equipment integrity
  • Sampling compliance
  • Corrective action implementation
  • Waterborne disease incident logs

Failure to Comply

Clause 9.2.1:

“Non-compliance with Schedule 1 shall be escalated to the DoE within 24 hours of detection, followed by a written corrective report within 7 days.”

Violations can result in:

  • Fines (scaled by risk level and number of violations)
  • License suspension or facility closure
  • Public disclosure in case of negligence
