Tim, Dorridge and knowle are lovely places to live in the midlands. I've done copious amount of work around Dorridge and maintained the the sewer line on the road you live on, on the Severn Trent contract. You must have a pretty penny to be living around there I say, not compared to the lot on bakers lane though :/
About 8 years ago we attended the house that opposite the railway tunnel (bakers lane) because an STW asset foul sewer blocked and FLOODED this chaps house, garden, green house and driveway with sewerage.
Me and my colleague felt absolutely helpless as we watched some of his belongings washing away down his back garden like a river. This was one of the worse case scenarios I've ever seen in my years in drainage. Me and my colleague managed to get the system cleared resulting in the longest clean up and disinfecting processes the company had undertaken.
Weeks this took, bloody weeks!
After this dreadful event, STW had spent hundreds of thousands of pounds in a maintenance programme for a routine cleanse in and around that area for the sewer lines to be surveyed and cleaned, hence knowing the area very well!
I just recognised the road sign in your shot!! (But you don't actually live on that road..........)
I promise I'm not a creep..... I just like walking around in the dark with a gas mask on flinging torches around and setting myself on fire!..... Oooohh, haven't done that in a while
