Kyd Brook

As already reported there has been a known misconnection on this S.W.O ever since I've been water monitoring but Thames water had been unable to resolve the problem but have investigated previously.

On 26/6/25 there was possible sewage fungus but the problem worsened significantly on 4/7/25, when there was sewage smelling discoloured water discharging from the S.W.O into Kyd Brook even though it was and had been dry. These were all reported and Thames water investigated that evening.

Today there was signs still of pollution, please see the picture of discoloured water but I haven't reported it because it's being dealt with and the ammonia levels are not high.

Thames water are still in a nearby residential road and some unfortunate residents are having parts of their gardens dug up as the pipe has collapsed and is leaching into the surface water pipe and needs replacing. There is a tanker 24hrs a day on site pumping when necessary which is causing understandable disturbance. To date there is no end date on when works will be completed.

From an observer of events certain things have amazed me.
The gardens are being dug by hand when there is access for a digger.
Residents are being told that once a pipe has been replaced, then cameras will go back in to check if there is any further problems, hence no timescale on when works will be completed.
The residents are being amazing as they obviously want this problem to be resolved but can't wait for it it be over, understandably.

There has been an ongoing pollution at this S.W.O since I started water monitoring back in 2023, this started as laundry detergent. Recently there has been the smell of sewage combined with laundry detergent. This has been reported please see previous notes.

Currently this pollution is being investigated by Thames water and will hopefully be fixed soon, also stated in previous notes.

This morning when I visited the S.W.O there was a smell of sewage combined with laundry detergent and discharge coming from the S.W.O. After taking samples and photos this has been reported to Thames Water and the environment agency ref 02408224. I recieved an email from Thames water saying that they will investigate further. The tanker in a residential road is now going more frequently which is causing distress to the residents. I do hope this is finally resolved soon.

Very pleased to report that there is no pollution at this site within Kyd Brook today, but there is a sewage collection vehicle at a house further upstream where the pipes run.

Thames water are digging up a collapsed drain and replacing it. There will be further investigations and hopefully this will finally be resolved.

There is a known misconnection on this S.W.O which has been reported to Thames water but they have been unsuccessful in finding it. There is often pollution at this site for this reason, last week there was possible sewage fungus. This week there is a slight smell of sewage and even though it's dry the S.W.O is discharging pale grey water into Kyd Brook that is spreading downstream. The water in the brook is low and slow running due to the dry weather and has natural debris within it plus silt at the bottom. This pollution has been reported on the government pollution website
https://www.gov.uk/report-water-pollution, ref 02404106.

Update. I recieved an email from the environment agency asking for photos and more information. They reported it to Thames Water who sent an investigation team out on Friday night. They have found a collapsed drain and somehow this has been leaching into the surface water drain. Some unfortunate homeowners have this drain in their back gardens and it's being dug up to replace the drain, whilst another homeowner has a sewage collecting vehicle connected to the drain.

Once this is done, there will be more explorations to see if the drain is collapsed further upstream, hopefully this will not be the case and it will be resolved, only time will tell.

Today there was a strong rotting smell with a hint of sewage and laundry detergent, it could be sewage fungus. This has been reported on the new government website for reporting water pollution in England ref - 02400689

There is a known C.S.O upstream. The E.D.M showed that the last discharge was on the 7th June 2025 from 17:45- 20:00 = 2hrs 45mins.

Also at this monitoring site there is a S.W.O with a misconnection meaning that there is often a smell of laundry detergent and visible signs coming from the S.W.O. This has been reported but to date the misconnection has not been found.

There is a known missed connection on the S.W.O, today there was a smell of Laundry detergent and a small grey /blue discolouration in the water nearby.

There is a known misconnection into this surface water overflow/S.W.O, which means that there is often laundry detergent entering the brook. There is a smell of old laundry detergent from the outlet.

The S.W.O (surface water overflow) which discharges into Kyd Brook has a known mis connection, this has been reported. At various there has been the smell and water discolouration of laundry detergent, today there was a sewage smell coming from the S.W.O.

This monitoring site has a S.W.O (surface water overflow) discharging into Kyd Brook, this S.W.O has a missed connection that has been reported to Thames water but to date this has not been found. The ammonia result was flashing 3, please see photos.
