A group of Kent villagers say they are suffering from physical illness due to a relentless sewage odour. The smell originates from a partially occupied housing estate in Herne Bay.
Residents of Chestfield live about one kilometre from the newly built Oxenden Park development. They claim the “horrendous” smell has completely upended their daily lives. This issue, which stems from the estate’s wastewater infrastructure, has triggered formal complaints to local authorities. Frustrated neighbours have even held public demonstrations in the path of the fumes.
Village life disrupted by “worst possible smell”
Homeowners in this quiet village report that the stench is now so intense that basic activities are impossible. They cannot open their windows or host guests in their gardens. The physical and psychological toll on the community has become a major talking point in the region.
“It makes your eyes water. It is the worst possible smell you can imagine,” said Celena Campbell, 71, who lives in Chestfield. She described the communal distress and noted that the fumes are so potent they caused at least one neighbour to be physically sick.
Another local, Mandy Friend, spoke of the frustration of being unable to escape the scent, even when she is tucked away inside her home. “It makes it really difficult to plan anything,” she explained. She has resorted to using “bottles and bottles of bleach” and burning scented candles. Despite these efforts, she says it is a futile attempt to mask the air.
Technical failures: The “low flow” problem
Investigations into the source of the odour point directly to the Oxenden Park estate in Greenhill. Bellway Homes is developing the site, but it currently sits at only 41 per cent occupancy. Engineers believe this specific figure lies at the heart of the crisis.
Because the estate is less than half-full, households simply do not generate enough wastewater. Without that volume, the system lacks the “flow” necessary to push sewage through the pipes toward the Swalecliffe Wastewater Treatment Works. Consequently, the waste sits stagnant within the network for long periods.
In these stagnant conditions, the sewage begins a process of anaerobic digestion. This produces hydrogen sulphide gas. This chemical reaction creates the sulphuric, “rotten egg” scent that drifts into Chestfield whenever the wind blows from the north-east.
Mitigation efforts and resident protests
Both Bellway and Southern Water have introduced several measures to combat the problem. Their current strategy involves:
- Adding chemical doses to the waste to neutralise rising gases.
- Installing specialised “douser” equipment at key points.
- Recalibrating sensors at the pump station to handle lower water volumes.
However, these interventions have not provided a permanent fix. Residents recently organised a protest to demand more aggressive, long-term action. They argue that temporary chemical treatments are failing to address a fundamental mismatch in the local infrastructure.
Official responses and infrastructure pressure
Bellway Homes has issued an apology to those affected. The developer acknowledges that the system is not yet functioning at its designed capacity. They maintain that they are working in tandem with Southern Water to resolve these “low flow” issues as more residents move into the estate.
Southern Water confirmed it is providing technical support and monitoring the local network. The company remains under significant pressure across the South East. In this region, rapid housing expansion frequently tests the limits of the ageing Victorian sewage and drainage grids.
Statutory nuisance investigation
The matter has now reached Canterbury City Council. Environmental health officers are investigating whether the stench legally constitutes a statutory nuisance. Documents from local parish meetings suggest that worries regarding the connection between the new development and the existing village pipes were raised as early as late 2025.
Local councillors have called for a halt to further connections until the developer can prove the smell is under control. They argue that the current situation is unfair to both the new arrivals at Oxenden Park and the long-term residents of Chestfield.
Until engineers find a permanent solution, or occupancy levels increase enough to naturally clear the pipes, the people of Chestfield remain caught in a cycle of environmental discomfort. They are left waiting for a breath of fresh air that remains, for now, elusive.
