What is DWI?

The Drinking Water Inspectorate (DWI) is an organisation which ensures water companies in England and Wales supply safe drinking water to consumers.

Regulation 31

Regulation 31 ensures that water suppliers, when producing and distributing drinking water, only use products and substances to that do not cause any detrimental effects on the safety or quality of the drinking water.

Drinking Water for Everyday Life

To further expand Fileder’s product range within the Municipal drinking water sector, we are excited to announce the release of the new DWI approved cartridge from Suez.

Specifically designed for utility companies providing safe, drinking water to end users, this cartridge offers a significant reduction in operational costs, is approved to DWI Reg 31 standards, and meets NSF 53 requirements, putting Fileder in the forefront of supply for the Municipal market.

With over a 60% increase in service life compared to comparable industry cartridges, the Abs.Za results in fewer changeouts, reduced downtime and lower on-going consumable costs.
