Win a once-in-a-lifetime tour of London's new super sewer

We bet you’ve never seen anything like this before. In the summer of 2024, the Thames Tideway Tunnel will be activated for the first time, preventing sewage overflows from spilling into the river. And to celebrate, Loo Gardens  – a subterranean oasis-meets-installation – is open to show off the positive environmental impact the super sewer will have on London. 

Be flushed away by an immersive experience that touches all the senses, including a bespoke soundscape and the aroma of grasses and wetlands. What makes it even more special is Tideway (the folks behind the project) have teamed up with environmental charity Thames21 to create elements of the gardens using repurposed waste cleared from the banks of the river. 

Once the super sewer itself is fully operational, it’ll prevent 95 percent of sewage spills and create a cleaner healthier river environment. So expect less-sludgy water and cleaner river banks. It also means better homes for the fish, birds, mammals and riverside flora populating the River Thames. How nice is that?

To get an inside look at the Loo Gardens project simply fill in the form between June 30 and July 4, and you’ll be in with the chance of winning. You’ll be among a handful of lucky ticket holders who will travel 50 metres below the city on July 10 to explore the underground garden on a private tour. You’ll also win eternal bragging rights.
