Biwater was established in 1968 by its current chairman Adrian White CBE. The name Biwater - or two waters - was adopted because of the company’s involvement in the provision of clean water and the treatment of wastewater.

Very early on in its history, Biwater located its offices at Dorking in the UK , giving easy access to London and its two main international airports.

During the past four decades Biwater has grown by expanding its own range of skills and expertise, by acquiring established companies within the water industry and by forming joint ventures with organisations that provide complementary services. In the 1970s Biwater extended its business activities into world markets with successful contracts in Indonesia, Hong Kong, Iraq, Kenya and Malawi. In 1975 the Company won the first of its five prestigious Queen’s Award to Industry for Exports.

To date, Biwater has operated in over 90 countries throughout its history. Today, it has over 30 businesses around the world, each serving clients within their own region and via excellent communication channels and IT networks.
