Supporting World Water Day: Train company’s smart water meters to save millions of litres a year
- All 235 GTR stations will have a smart water meter by this summer
- Constant monitoring and leak alerts could save 40 million litres a year – 130,000 baths or 174 million cups of tea
- GTR’s station improvement programme will also save water by creating wildflower areas
Govia Thameslink Railway (GTR) has announced on World Water Day [Monday 22 March] that it will install smart water meters at all 235 of its stations. The project could save around 40 million litres of water every year.
GTR, which runs Southern, Thameslink, Great Northern and Gatwick Express, now has water monitoring systems in 135 stations. As part of the company’s network-wide, multimillion-pound station improvement programme, the remaining 100 will have their water monitoring systems fitted by the end of June.
The systems provide a moment-by-moment measure of water flows at each station. Head-office staff get automatic alerts to any unusual change in the flow rate, so they can check for leaks and get them fixed quickly.
Based on the reduction in water use already tracked by the new meters, GTR’s environment team estimates that monitoring across the network will save more than 39 million litres of water every year. That’s enough to fill 15 Olympic-sized swimming pools, 130,000 bathtubs, or 174 million cups of tea!
Tom Moran, Managing Director for Thameslink and Great Northern, said: “The biggest benefit is leak detection. We can spot a likely leak immediately – the system automatically sends a warning email if the water flow is higher than expected. That means we can get it fixed in a matter of days, instead of waiting up to six months for the water company statement. We can also now spot if a particular station is using more water than we would expect for its size, and look into it straight away.
“Using these meters we’ve already reduced our water usage by six per cent over the past year. That’s 25 million litres saved. This is all part of our determined drive to build back greener. We’re making our stations more sustainable, reducing our utilities costs and doing our best to help save the earth’s precious resources.”
Other water-saving measures at GTR stations include the “wilding” of landscaped areas with plants that need less frequent watering. Platform drainage improvements by Network Rail are allowing more rainwater to soak away into the ground rather than evaporating.

Notes to editors
World Water Day, held on 22 March every year since 1993, celebrates water and raises awareness of the 2.2 billion people living without access to safe water.
About GTR’s wider station improvement programme
GTR’s network-wide, multimillion-pound improvement programme involves over 1,000 projects, many of which were suggested by local passenger and community groups, at more than 250 stations. While we’re working hard to achieve the punctuality and reliability our passengers rightly expect, we want them to know we are with them all the way and making their stations better places to pass through.
The vast number and range of improvements can be described under three themes:
1. Giving many stations a better ambience by redecorating, planting and installing artwork, often with substantial input from the local community
2. Making stations work better for passengers, improving comfort and safety with new waiting rooms and shelters, seating, lighting, information screens, defibrillators for public use, and accessibility schemes
3. Making stations more sustainable, with schemes such as electric vehicle charging points, secure facilities for cyclists, rainwater retention systems, and even bee gardens.
We’ve created dedicated web pages where passengers and local communities can get updates on what’s happening at their station. They can be found at:
