Key Points
- A request for Environmental Information Regulation (EIR) from environmental charity Friends of the River Crane Environment (FORCE) has shown that there have been several residential developments which have been releasing raw sewage into local rivers.
- Out of the seven misconnections that have been found in London, two are from London Borough of Ealing where the wastewater is being released into River Brent.
- While Thames Water had been aware of one Ealing site, which is a housing estate containing 14 homes, since 2018, other misconnections in the area were detected in 2021, 2023, and 2024.
- Environmental campaigners pointed out that developers had not taken any steps to fix plumbing issues, with even one case of efforts to shift blame for the repairs to flat leaseholders.
- Campaigners and trustees from the local charity had condemned the issue as a catastrophic failure of regulation since houses were being constructed, sold, and marketed with faulty surface water drainage connections rather than proper foul sewer connections.
- According to Thames Water, fixing misconnections was legally the duty of property owners and developers, although Thames Water conducted investigation schemes to detect and inform the guilty parties.
uk/local/ealing/">Ealing (West London Times) — September 07, 2024 — Fresh scrutiny has fallen on housing developments across west and north London following revelations that newly constructed properties have been unlawfully flushing raw sewage directly into local tributaries of the River Thames. As reported by environmental campaigners and local news sources, an investigation triggered by an information request exposed serious plumbing failures that have allowed waste to bypass treatment works for years.
What Did the Environmental Information Request Reveal About Ealing’s Rivers?
According to findings uncovered via an Environmental Information Regulation (EIR) request submitted to Thames Water by the environmental charity Friends of the River Crane Environment (FORCE), seven housing developments across the capital were built without proper connections to the foul sewer network. Instead, toilets and washing facilities were plumbed directly into surface water drainage systems.
As detailed by local media outlets, five of these developments discharge directly into the River Brent, while others impact the River Crane. Within the London Borough of Ealing specifically, two separate housing schemes are implicated. Thames Water records show that the utility company has been aware of one 14-unit residential estate in Ealing discharging sewage continuously since 2018. A second Ealing development was identified more recently.
How Have Campaigners Responded to the Pollution Findings?
Environmental groups have reacted with deep concern and anger over the prolonged discharge of untreated wastewater into urban waterways. FORCE reported that none of the developers responsible have taken proactive steps to resolve the structural misconnections. Furthermore, campaigners noted that in at least one instance, attempts have been made to shift the financial burden of fixing the plumbing onto innocent leaseholders.
As reported by Cesar Medina of Ealing Nub News, FORCE Trustee Rob Gray stated: “We were appalled at the extent of this pollution problem and by the approach shown by the developers and/or freeholders – in first allowing this gross misconnection failure to be constructed, then failing to resolve it for up to six years, and finally (in at least one case) apparently attempting to pass on the costs to the leaseholders.”
Adding to this criticism, Ben Morris, a Brent River Park charity trustee and founder of the Clean Up the River Brent campaign (CURB), described the situation as an institutional breakdown. As covered by regional reports, Ben Morris stated:
“This is a catastrophic failure of regulation. It is now possible to build, market and sell properties that flush sewage straight into our rivers, and no-one spots it until it is too late.”
He further emphasized that sewage pollution destroys aquatic wildlife, transforming healthy natural rivers into open drains, and argued that the issue intersects directly with the broader leasehold scandal where residents are left footing bills caused by builder negligence.

What is Thames Water’s Position on Property Misconnections?
Thames Water has responded by asserting that while misconnections severely damage local ecosystems, rectifying the underlying plumbing is legally the responsibility of the property owner or developer.
A Thames Water spokesperson explained the scope of the problem to local democracy reporters, noting:
“Households and buildings which are connected to the wrong drainage pipe can have a serious impact on the environment. Most misconnections will have been done entirely by accident but it is the responsibility of the property owner, which is why we would urge freeholders or developers fitting new connections to make sure they’re plumbed in properly.”
The water utility added that it has identified the seven buildings across the Brent and Crane catchment areas and notified those responsible to ensure wastewater is redirected safely to sewage treatment works. Thames Water also maintains ongoing investigation programmes and supports community projects to boost environmental awareness, though external critics argue that tougher legal enforcement and stricter pre-occupancy building inspections are urgently required.
Background of the Particular Development
The revelation of sewage misconnections in Ealing stems from a broader systemic pattern involving newly built residential blocks across London boroughs like Ealing, Barnet, and Harrow. Over recent years, environmental charities such as FORCE and local clean-up initiatives like CURB have increased scrutiny on urban river catchments, particularly the River Brent and River Crane. Historically, oversight regarding plumbing infrastructure relies heavily on initial developer self-certification and building control sign-offs. However, these recent Freedom of Information and Environmental Information Regulation requests have demonstrated that faulty installations—where foul water pipes are mistakenly or negligently linked to surface water drains—can go undetected for years, continuing to bleed raw sewage into local waterways long after residents move in.
This ongoing regulatory and environmental development carries direct financial and health implications for local residents, property leaseholders, and the wider Ealing community. If local authorities, water companies, and the Environment Agency do not enforce strict legal accountability, flat owners and leaseholders face the risk of absorbing exorbitant repair bills to fix developer-created structural flaws. For the broader public and local wildlife, continuous untreated sewage discharges degrade local green spaces, damage biodiversity in the River Brent, and erode public trust in housing development standards and environmental regulation enforcement.
