The Thames Tideway Project has been almost as complex and challenging as Crossrail, according to Harbinder Birdi. He has worked on both. Harbinder is the Head of Infrastructure at Hawkins Brown, and we are grateful to him for his fascinating introduction to this enormous project. The Thames Tideway takes surface water and sewage from Acton to Beckton, connecting up to the old Victorian sewers designed by Bazalgette which were designed for a city of 2 million people. When it is completed in about 3 years time the new sewer will be able to serve a population of 8 million, resulting in far fewer discharges of sewage into the Thames and less flooding. The Tideway will create large public spaces along the Thames which are being planned by multi disciplinary teams of architects, engineers, designers and artists. Each will be different and will reflect the local area. The new public realm at the Chelsea embankment for example will feature a variety of different planting on tidal terraces. Other spaces have sculptures, a waterfall, seating, performance space and design work referencing links to the Victorian past of the original sewers. The picture shows the first shaft which is in Acton, 5 minutes from the Uxbridge Road. Harbinder’s talk was our first virtual annual John Delafons Lecture. He certainly made it a success. If you missed it the lecture is now available on our YouTube channel. We are very grateful to Harbinder Birdi for delivering the lecture and to him and Hawkins Brown for making it available to us, and for their technical support with the process.
