Drainage ditch : Land Drainage Ditch on ede of Fox Corner Nature Reserve

After find the grey water in the ditch and testing it, we decided to try and find where the water was coming from. Nigel knew where there was a culvert emptying into the ditch and we found a lot of water entering the ditch at that point and the water was quite grey and cloudy.
We went round to a neighbouring road adjacent to the sewage works and saw water bubbling up from the verge before travelling down the road and into road drains.
We went to the Sewage Works to see if there was a number to ring and found some people from Thames Water (sewage works owner) and Affinity Water (drinking water provider). The burst pipe was thought to be drinking water pipe that travels through the edge of the STW before going to the houses.
The pipe had been burst since at least 6am and so it is likely that the water flowing over the road had carreid road debris into the culvert and land drainage ditch.
The land drainage ditch does not flow at any speed, even in winter and a build-up of rotting vegetation is common in it. This may have added to the poor quality of the water on this date.
The Thames Water representative took photos of the data collected at the ditch and Hodge Brook for their information.
