Drinking Water Inspectorate (DWI)

The Drinking Water Inspectorate (DWI) is the regulator responsible for ensuring that water companies in England and Wales supply safe, clean drinking water. It holds these companies accountable for meeting stringent quality standards. The DWI is currently newsworthy due to recent water supply failures in Kent, specifically in the Tunbridge Wells area. A failure at the Pembury water treatment centre left 24,000 homes without water for two weeks, and a separate incident impacted 6,500 households. The DWI has stated that the Pembury failure was foreseen and preventable, raising concerns about the water company's preparedness and investment in infrastructure. These events highlight the DWI's crucial role in overseeing water companies and ensuring they prioritize infrastructure maintenance and resilience to prevent disruptions to public water supply.
