London’s iconic river, the Thames, has been the lifeblood of the city for centuries. However, the river’s importance also means it has faced its fair share of pollution and contamination from human waste, sewage, and industrial waste over the years. To combat this problem, the Thames Tideway Tunnel project was launched in 2010 to create a new underground tunnel to capture and clean the wastewater that currently flows into the river. The kind of project that makes one ask, ‘How on earth is the Thames Tideway Tunnel funded?’
The project is estimated to cost £5.5 billion and be completed by 2025. This level of investment might make you wonder whether the government is contributing to the funding. In reality, the project is wholly funded independently, without any government support. Instead, the financing model is based on a partnership between Thames Water and a group of investors known as the Bazalgette Tunnel Limited (BTL), who have the mandate to finance, operate and maintain the project.
To fully appreciate how the Thames Tideway Tunnel is funded, it’s essential to understand the financing structure of the project. This innovative financing model uses a combination of bonds issued directly to institutional investors, private placements, and bank loans, which are then repaid through a fixed, inflation-linked cash flow generated by Thames Water, through levies collected from the companies and individuals that use the Thames sewer system. This financing model is attractive to investors, because it offers a steady and predictable stream of income, which can be used to repay the loans over the project’s long life.
The History of Sewage Treatment in London
London’s sewage system has come a long way from the early days of unsanitary cesspools that led to widespread disease outbreaks. The city’s sewage system was initially designed to transport waste from homes and businesses to the River Thames. However, this practice led to the river becoming heavily polluted, resulting in public health hazards and environmental degradation.
In the mid-19th century, the ‘Great Stink’ of London brought the issue to the forefront, finally leading to the construction of the city’s first sewage treatment works. Built in 1865, the sewage works was the first step towards a comprehensive sewage system in London.
Over the years, London’s sewage treatment systems have gone through several upgrades and revamps to keep up with the growing population and advancements in technology. Today, the responsibility of the city’s sewage treatment is in the hands of Thames Water, the UK’s largest water and wastewater services company.
Key Milestones in the Development of London’s Sewage Treatment
- 1865: The first sewage treatment works opened in Crossness, South-East London.
- 1882: The Royal Commission on London’s Sewage Discharge established guidelines for sewage treatment in the city, leading to the construction of several additional treatment plants.
- 1900: The city’s sewage system was again improved with the construction of new intercepting sewers and treatment works.
The Thames Tideway Tunnel
The Thames Tideway Tunnel is a major new infrastructure project that is set to transform London’s sewage system. The tunnel will prevent untreated sewage from entering the River Thames and improve the water quality of the river.
The project, which is expected to be completed by 2025, is being funded primarily by Thames Water customers through their water bills. However, the government is also providing some financial support.

The project involved significant collaboration between the constructors and environmentalists to come up with solutions that safeguarded the ecosystem. Here are some of the eco-friendly techniques that were used in the construction of the Thames Tideway Tunnel:
- Reusing excavated materials: The tunnel involved the excavation of millions of tonnes of materials, which were then transported to the Wallasea Island Wild Coast Project in Essex. The site is being developed as a nature reserve, and the excavated materials are being used to create habitats for different species such as salt marshes, creeks, and mudflats.
- Energy usage and carbon footprint reduction: The constructors adopted various forms of energy-saving techniques, such as the use of energy-efficient equipment, machinery, and lights. There was also the installation of solar panels in the riverside sites and offices, reducing energy costs and carbon footprint.
- Use of renewable energy: Renewable energy sources such as wind and hydroelectric power are increasingly being adopted in many construction projects. The Thames Tideway Tunnel project specifically used hydroelectric turbines that generated power from the tidal flows, easing the reliance on mains electricity.
Waste Management and Recycling
Construction sites generate a lot of waste, and the Thames Tideway Tunnel project was no exception. However, it was necessary to dispose of the waste sustainably to prevent environmental degradation. The constructors, therefore, came up with a comprehensive waste management and recycling program that included:
- The segregation of waste into different categories such as metal, concrete, and wood for easier recycling.
- The implementation of a closed-loop system that saw the reuse of excavated materials, reducing the amount of waste that needed to be transported to landfills.
- The reduction of the amount of single-use plastic on the construction sites through the use of reusable cups and bottles.
Ecology and Biodiversity Protection
The Thames Tideway Tunnel construction cut through ecosystems that demanded the preservation of habitats and ecosystems of species that live along the River Thames. To achieve such a goal, the constructors:
- Developed bespoke designs of machinery that made it easier for work in cramped quarters with reduced noise pollution and vibration to reduce damage to fish and other river species.
- Implemented strict controls on marine dredging to prevent excessive damage to the seafloor and reduce sediment blocking the sunlight.
- Deployed marine mammal observers on the sites whose primary responsibility was to protect marine mammals from construction activity, taking observations of marine mammals in the surrounding area, checking the environmental conditions, and informing the construction team about how drilling could affect the marine environment.
Friendly Measures to Community and Stakeholder Engagement
A project that involves the construction of a tunnel that is several kilometers long under densely populated London neighborhoods is bound to have an impact on the lives of the community living in the surrounding area. The constructors of the Thames Tideway Tunnel project understood the social responsibility of ensuring that the construction process should have the least impact on the daily lives of those living around the river Thames. To achieve this, the constructors adopted several measures to keep the community informed and engaged throughout the construction process.
|Public information centers||The TTC project established a series of community locations and offices across the length of the construction of the project, which provided up-to-date information about the project and its impacts.|
|Community Liaison teams||Each main construction site employed a team of community liaisons to provide a personal point of contact for the project for the local community. They act as a link between local communities and TTC’s project teams.|
|Task force groups||For areas of the community that were particularly affected by the construction works, the TTC established task force groups made up of representatives from each group. The groups meet regularly with project representatives to discuss issues and find ways to minimize the impact of the works.|
By incorporating these measures into the project, the constructors were able to keep all stakeholders informed about the construction process and considerate of the public’s needs during the short-term disruption.
