Part of the Thames Tideway Tunnel turned into “Loo Gardens”

London’s Thames Tideway Tunnel, also known as London’s Super Sewer, has been transformed into a colorful garden, 50 meters under the city.

This initiative is part of the “Loo Gardens” installation, which was created to symbolize the healthier future of the river Thames, according to the developers.

Loo Gardens aims at creating an underground oasis for a brief period of time, using rented artificial plants and repurposed waste material, which were found along the Thames, due to the challenges of darkness and watering.

As far as the original project is concerned, the Thames Tideway Tunnel is a 25-kilometer super sewer which is currently being constructed under the city of London, at a cost of £4.5 billion, and is scheduled to be operational in 2025.

The project aims to prevent some millions of tons of raw sewage, or about 95% of today’s spills, from entering the Thames through the Victorian sewer system, which is in place today.

Finally, Loo Gardens will be open for three weeks, before the tunnel is closed prior to being tested before coming into operation, while some lucky Londoners will have the chance to visit the installations through a competition in Time Out magazine.
