Twyford Waterworks

100 years of history

Twyford Waterworks is an Edwardian pumping station with a unique array of buildings and machinery.

The site retains nearly all its original equipment. This includes five large lime kilns, a water-powered narrow gauge incline railway and the entire water-softening process. These artefacts help to tell the story of water extraction, softening, and supply.

The site has been carefully restored and is managed by the Twyford Waterworks Trust volunteers. In 1973, Twyford was given the status of a Scheduled Ancient Monument and English Heritage describes it as ‘exceptional’.

"A rare ‘time capsule’ Edwardian waterworks... exciting opportunities for people of all ages to get involved in the heritage on their doorstep."

Stuart McLeod, Head of the Heritage Lottery Fund for South East England

The heart of the waterworks

Twyford Waterworks is still operational and supplies five million gallons of water every day. Constructed between 1898 and 1935, the site features three main buildings:

  • The Engine House. This contains the large 1914 Hathorn Davy triple expansion steam pumping engine. This heritage steam engine is capable of pumping to the Water Softening Plant and the service reservoirs.
  • The Boiler House. In this house, you can find three Babcock and Wilcox boilers dating from 1906, 1903 and 1916. Today, they are the last surviving complete set of water tube boilers in the country.
  • The Diesel House. The pumping station was modernised in the 1930s with three modern diesel engines from Rustons. Two of the engines are in working order and run on open days. The third is undergoing long-term restoration.

History in motion

A 2ft gauge railway to transport materials around the site was laid soon after the site opened. Skip wagons were used for all operations, pushed by hand on the level sections and pulled by rope up the inclines.

Much of this railway remains in place today along with a new track. Visitors can enjoy demonstrations of typical small locomotives shunting a variety of wagons.
