Lambeth Waterworks Company

The Lambeth Water Works Company was incorporated by Act of Parliament in 1785 to supply the Parish of Lambeth and adjacent areas. The original Works, consisting of an intake and pumping station, occupied part of the Royal Festival Hall site.

As demand for water supply grew the company extended its works and in 1832 an open reservoir was completed at Streatham Hill. In 1834 the company built two further reservoirs containing rough filters at Brixton and pumping engines were installed to supply water to the higher areas. The works at Brixton became the company's main distribution station.

By 1847 the quality of the water supply opposite the Festival Hall site had deteriorated to such an extent that the company decided to promote a bill in Parliament to enable new works to be constructed at Long Ditton. In 1848 the bill was passed and the new works were inaugurated in 1852. The periodic incursion of flood water from the River Mole induced the company to draw its water from further up the river and in 1872 a new intake was opened at West Molesey, reservoirs being added there in 1874 and 1903.

By the end of the century the works at Brixton and Long Ditton had grown considerably and service reservoirs for filtered water had been constructed at Coombe (1864), Norwood (1877), Rock Hill (1857) and Selhurst (1861).

By another Act of 1900 the company were granted powers to construct a large storage reservoir at Island Barn, Molesey. This was eventually inaugurated in 1911 by the Metropolitan Water Board who had taken over the functions of the company in 1904, following the Metropolis Water Act, 1902.
