Achieving DWI Approval for Clean Water Applications (Award)
De Havilland Fabrication is proud to announce that we have officially achieved Drinking Water Inspectorate (DWI) approval for clean water applications across England, Wales, Scotland, and Northern Ireland.
What This Means
The Drinking Water Inspectorate (DWI) regulates public water supplies in the UK, ensuring that all materials, processes, and equipment that come into contact with drinking water meet stringent national safety, hygiene, and water quality standards under Regulation 31 (and devolved equivalents).
Achieving this approval verifies that our fabrication processes, materials, and finished installations:
Protect Water Quality: Comply fully with UK public health and clean water safety regulations.
Deliver Compliant Solutions: Eliminate contamination risks when fabricating components intended for potable water treatment, storage, and distribution.
Support Utility Frameworks: Enable water authorities, tier-one contractors, and infrastructure partners to commission custom fabrications with full regulatory compliance.
Serving the Clean Water Sector
Whether providing bespoke pipework, access platforms, structural frameworks, or specialized assemblies for clean water treatment works, our DWI-approved status gives our clients complete confidence in quality, compliance, and structural integrity.
