Water Act 1973 resulted in the formation of the
Southern Water Authority (SWA), taking the responsibility away from the local authorities. Nevertheless, the SWA maintained a regional management approach, retaining three separate regional headquarters: •
Otterbourne near
Winchester, covering
Hampshire and the
Isle of Wight •
Falmer near
Brighton, covering
East Sussex and
West Sussex •
Chatham, covering
Kent. The authority took over the assets and duties of the following water undertakings: • Hampshire River Authority • Sussex River Authority • Kent River Authority • Brighton Corporation • Hastings Corporation • Southampton Corporation • Tunbridge Wells Corporation • Winchester Corporation • Worthing Corporation • Isle of Wight River and Water Authority • Medway Water Board • North West Sussex Water Board • Thanet Water Board A number of private statutory water companies existed within the water authority's area.

Folkestone and District Water Company •
Mid Kent Water Company •
Mid-Sussex Water Company •

Thanet Water Board Privatisation In 1989 the ten publicly owned water and sewerage authorities were privatised. This was achieved by transferring the water supply and sewerage assets, and the relevant staff, of the Southern Water Authority into the limited company
Southern Water Services Ltd. Privatisation was accompanied by the raising of capital by floating parent companies on the
London Stock Exchange, a one-off injection of public capital, the write off of significant government debt, and the provision of capital tax allowances.
Takeovers In 1996 Southern Water was purchased in a
hostile takeover bid by
Scottish Power. Southern Water assets were considerably impacted during the period under Scottish Power. During this period, the bulk of in-house scientific laboratory services and assets were shut down, dismantled and sold off. In 2002, Scottish Power sold the company to First Aqua Limited.
