Thames Water Scheme Threatens 500-Runner Kingston Parkrun Event: Kingston 2026

Key Points

• According to Kingston upon Thames council, the TDRA scheme proposed by Thames Water has the potential of bringing the weekly Kingston Parkrun of 500 runners to a permanent standstill.
• The revised plans on the development of Burnell Avenue Open Space include installation of 34 inspection hatches, extended development time, an increase in heavy goods vehicles and a more substantial physical footprint.
• The Kingston council says it is “extremely likely” that the free weekly race would have to stop permanently due to physical and safety issues.
• Thames Water disagrees with the suggestion that the parkrun will come to a standstill, adding that it is able to continue either alongside or after completion of the project.
• The disputed project entails pumping of effluent from the Mogden sewage treatment works to the River Thames to ensure security of London’s water supply during times of severe drought.
• The controversy comes amid tough financial and operational pressures on Thames Water.

Kingston (West London News) September 5, 2026 — As reported by local democracy reporters covering south-west London local government, Kingston upon Thames council has warned that Thames Water’s revised infrastructure designs for the richmond-upon-thames/teddington/">Teddington Direct River Abstraction scheme threaten to permanently end the weekly 500-runner Kingston Parkrun. Every Saturday morning, more than 500 runners gather on a section of grass at Burnell Avenue Open Space in south-west London before making their way along the Thames towpath. Kingston council has formally stated that updated engineering proposals—which include installing 34 inspection hatches across the green space—would scatter so much heavy construction infrastructure across the site that the community fitness event would become unviable. Thames Water has publicly rejected the council’s assessment, insisting that the event can be accommodated and continue. The dispute comes as the UK’s largest water utility continues to navigate intense commercial pressure and heightened scrutiny from industry regulators.

What is Thames Water proposing for the Teddington Direct River Abstraction scheme?

The Teddington Direct River Abstraction (TDRA) scheme is designed as a strategic drought-resilience measure to safeguard London’s long-term drinking water supply. Under the current proposal, Thames Water intends to abstract up to 75 million litres of water daily from the River Thames near Teddington Weir during periods of prolonged dry weather. The abstracted water would be transferred via a new underground pipeline into existing storage networks to feed the capital’s drinking water infrastructure.

To replace the removed river water and maintain flow levels, highly treated wastewater would be pumped back into the Thames from the Mogden sewage treatment works located in Isleworth, west London. According to technical documentation detailing Mogden’s infrastructure, the facility frequently operates near maximum capacity during heavy rainfall events, resulting in storm discharges into the local water ecosystem roughly fifteen times a year when capacity limits are exceeded. Thames Water maintains that expanding tertiary treatment processes at Mogden and cycling treated effluent into the Thames is essential to offset climate change impacts and population growth across Greater London.

Why is Kingston council warning that the weekly 500-runner event could stop permanently?

The conflict between local authorities and the water operator centers on updated construction and maintenance plans submitted for Burnell Avenue Open Space. Kingston upon Thames council confirmed that recent engineering modifications expanded both the temporal scope and physical footprint of the project on the public park.

According to statements released by Kingston council via the Local Democracy Reporting Service, the primary design revisions include:

• A significantly extended construction timeframe across Burnell Avenue Open Space and adjacent roadways.
• A marked increase in heavy goods vehicle (HGV) movements through residential access streets.
• The placement of 34 distinct inspection hatches across the open green space.
• Expanded ongoing access requirements for construction personnel, heavy machinery, and long-term utility servicing.
• A substantially larger permanent and temporary infrastructure footprint within the park boundaries.

“When the works are complete there will be 34 inspection hatches in Burnell green space which impinge on this,” Kingston council stated in documentation reviewed by local democracy reporting staff. Council representatives added that the resulting disruption makes it “extremely likely” that the weekly 500-runner Kingston Parkrun will be forced to stop permanently due to space constraints, surface hazards, and route access issues.

How has Thames Water responded to the local council’s concerns?

Thames Water has strongly contested the council’s assertion that the community running event will be drawn to a permanent close. In response to the council’s assessments, representatives for the utility stated that engineering plans are crafted to preserve access to public open spaces wherever feasible.

Thames Water representatives noted that engagement with local authorities, land managers, and community sports organizations remains ongoing. The company maintains that temporary traffic management, revised site layouts, and phased works will allow construction to proceed without necessitating the permanent cancellation of Kingston Parkrun. The utility emphasized that the development consent application process includes rigorous environmental impact assessments intended to mitigate disruption to local recreational activities.

What is the background of Thames Water’s Teddington project and operational performance?

The controversy surrounding the Burnell Avenue site is the latest chapter in a multi-year effort by Thames Water to secure government approval for large-scale strategic water resource options. The Teddington Direct River Abstraction project was categorized as a Development of National Significance, placing the ultimate planning determination in the hands of the Secretary of State via a Development Consent Order (DCO).

The scheme has faced sustained opposition from local residents, environmental campaigners, and municipal leaders in both Kingston upon Thames and Richmond upon Thames. Opponents have raised concerns regarding potential changes to river temperature, water chemistry, local ecological habitats, and long-term disruption to historic riverside parks.

Concurrently, Thames Water is operating under severe financial and regulatory headwinds. The company is managing billions of pounds in corporate debt while attempting to secure emergency capital restructuring to maintain daily operations. The utility has also faced significant fines and enforcement actions from the water industry regulator, Ofwat, alongside the Environment Agency, following widespread public outcry over sewage spill frequency, system leakage rates, and deferred maintenance across its vast piping network in London and the Thames Valley.

How could this development affect local communities, runners, and public stakeholders?

The dispute over Burnell Avenue Open Space directly affects several distinct interest groups across south-west London:

1. Local Runners and Volunteer Networks

For the 500-plus participants who gather every Saturday morning, as well as the dozens of unpaid volunteers who organize the route, the potential cancellation of Kingston Parkrun represents a significant loss of local community infrastructure. If the event is forced to cease operations or relocate, participants face the loss of a free, accessible health initiative that has operated continuously along the Thames towpath for years. Relocating a 500-person event within urban London presents major logistical challenges due to land ownership rules, path widths, and local park council permissions.

2. Local Residents and Road Users

Residents living along Burnell Avenue and surrounding suburban streets in Kingston face several years of heightened heavy vehicle traffic, noise, and localized congestion. The installation of 34 inspection hatches on green space permanently alters a local park used daily by dog walkers, families, and pedestrians, reducing the area of uninterrupted grass available for public recreation.

3. Thames Water and London Ratepayers

For Thames Water’s management and its customer base across Greater London, the legal, political, and public opposition at Burnell Avenue creates potential timeline delays for a critical national infrastructure project. Protracted disputes with local authorities can drive up overall project delivery costs and delay the operational launch of drought defense mechanisms, leaving London’s broader population more vulnerable to municipal water restrictions during future prolonged dry spells.
