Described by DCMS as "the most important historic site of the water supply industry in Britain" the London Museum of Water & Steam (LMWS) shares the history, science and the stories behind London's public water supply.

Housed in a Georgian water pumping station in Brentford, West London, the museum is built around a collection of steam engines which pumped clean water into the homes of millions of Londoners between 1838 and 1944. 

However, without donations to fund conservation, The Great Engine House and the engines it contains could be lost forever. We are asking urgently for your support to save these pieces of London's history.

Why is The Great Engine House so important? 

The Great Engine House is a Grade I listed engine house, which is home to the gigantic Grand Junction 100 Inch and 90 Inch engines. Both three stories high, these marvels of Victorian engineering were built powerful enough to supply water to areas of London as far as Notting Hill and Kensington, and to the upper floors in buildings – helping to transform London into the multi-story city it is today. The 90 Inch was installed in 1846 and ran daily for over 100 years and the 100 Inch was on standby until 1954. Today the 90 Inch is one of the largest working beam engines of its type in the world! 

Our challenge

A funding and maintenance backlog has led to severe degradation of the 100 Inch and 90 Inch engines, and the Grade 1 listed Great Engine House. Covid lockdowns have accelerated the damage, due to a lack of people available to maintain the site coupled with little ventilation while closed, and the need for expensive scaffolding that we haven't been able to afford.

A recent site survey identified the Engine House as the priority building and a costed, full building condition survey shows a leaking roof structure, dry rot, blown and spalling render, corroded window frames and cracked glass, collapsed storm drains, loose plaster and paint finishes, and both engines are actively corroding and contain encapsulated asbestos lagging.

Why now?

Unless work is undertaken in the next two years to stop this decay these historically significant machines could be lost, and central parts of the museum building will be closed off.

Access to clean water is more important than ever, with London being number nine on the list of global cities most likely to run out of water. Our site and our engines are crucial to telling the story of London's journey from deadly to clean drinking water and encourages visitors to consider their role in environmental sustainability and the preservation of water in an increasingly uncertain future. 

How can you help?

As a charity, we rely on the generosity of supporters who believe the UK's rich heritage is worth protecting. 

We are at an advanced stage of receiving a funding grant for the entire project of £2.8 million, however, we will need to raise a percentage of the grant through crowdfunding.

We need your help to raise £50,000 by mid-August.

Can you help us reach our target and save this historic landmark for the local community and for future generations?
