In January, United Utilities carried out drainage surveys on a lot of properties in my area to check for contamination of the surface water drains. They have written to me this week to tell me that, when I had a ground floor shower/basin/wc installed 9 years ago, it has been plumbed into the surface water drain. It looks to me that the architect drew up correct plans but the builder has fed into the surface water drains (which ran adjacent to the location of the shower room) rather than plumb into the foulwater drains. The council building inspector visited and approved all the below ground works. I am obliged to get this rectified but couldnt afford to do it myself and shouldnt have to pay when the error is not mine.
How do I get the builder/council to correct their errors and who do I approach first ?
