Our Legacy

The scale of the Tideway project, and its place at the heart of one of the world’s greatest cities, means we have an historic opportunity to leave a positive, lasting legacy for London.

Yes, the super sewer will prevent millions of tonnes of sewage entering the river each year – with all the ecological and health benefits that will bring.

But we’re going far beyond simply building a tunnel.

We’re creating new public spaces in the Thames – the first new land in London for generations. We’re raising the bar for health, safety and wellbeing in the construction industry and using the river to transport material on an unprecedented scale, bringing jobs and recreation back to the river.

Beyond that, our investment in local communities, education, training and the supply chain will ensure that the legacy of the Tideway project will be profound and long-lasting, far outliving the construction of the super sewer.

We're working to minimise our impact on the environment by using greener fuels, innovative construction materials, and mitigating our carbon footprint. 

Tideway has funded research into the ecology of the tidal Thames to provide baseline data which will provide comparisons for future research into the river and its wildlife.

We're using the river as a transport route to and from site, moving spoil and materials by barge.

Our use of the river keeps lorries off London's already congested roads, and produces far fewer emissions compared to the HGV equivalent. 



Our targets ensure we create a diverse and inclusive workforce. More than 4,000 sustainable jobs have been created on the project.


More than 100 apprentices have already been employed by Tideway

We track where the Tideway pound has been spent and we are proud to report that to date around 90 per cent of our spend has been in the UK. 

We're also mindful of how we raise finance for the project and are one of the largest issuers of green bonds in sterling worldwide, having raised £1.6bn in green financing. 


Keeping everyone working on the project safe, healthy and happy is a fundamental philosophy at Tideway
– we do things safely, or not at all.

At Tideway we do it the RightWay!
