A brief history

Works begin at Longham and the first reservoirs and filters are built at Alderney, where Bournemouth Water is now based.


The West Hampshire Water company is established and Knapp Mill in Christchurch becomes a pumping station two years later.

The two water companies expand their supply areas and construct boreholes, reservoirs and water towers. As modernisation takes place, steam-powered pumps are replaced by diesel and electricity.


Bournemouth Water and West Hampshire Water come under a joint majority shareholding through Biwater, a British multinational water engineering group, to take advantage of new opportunities from the privatisation of the former Water Authorities in 1989.
