Thames Pulse, an innovative light installation that will reflect the health of London’s river on a daily basis, is to be unveiled this week, becoming a new landmark on the South Bank of the Thames. The giant interactive work of art on the front of the 13-storey hotel at Sea Containers House will use data from river water samples to create a new display every day.

The installation is the work of artist Jason Bruges, previously known for his light displays at the top of the Shard. The aim is to raise public awareness about the condition of the Thames on behalf of the environmental charity Thames21 – as well as adding a beautiful new attraction to the capital.

Thames21 collects data about the river’s health through its Thames River Watch citizens' science project, supported by Tideway, the company delivering the super sewer in London. The Thames Pulse water quality updates will be posted regularly on a Twitter Feed @ThamesPulse and webpage.

Through Thames Pulse, Thames21 also aims to highlight its other projects to improve understanding and cleanliness of the river so Londoners can help to improve the Thames’ health in their daily lives. This ranges from not pouring detergents and other pollutants into rainwater drains in the road, to taking part in volunteer groups, or just reducing reliance on plastic packaging and disposing of plastic water bottles and other packaging responsibly.

The lights are being officially switched on at Sea Containers House on the evening of 16 March 2017.
