Then did you know that the 'moratorium' for allowing them to discharge directly into a watercourse expires Jan 2020. General Binding Regulations explain it all. Severe penalties for continuing to do so and, of course, if you come to sell your property and the purchasers' solicitors are on the ball then you could have some problems with the sale.
Have discovered that ours, and contrary to what the vendor told us in writing when we bought the place, does not discharge to land (ground) but into the stream.
Vendor claiming caveat emptor...I have Which Legal and so in contact with them. Our new 'local' solicitor wants to go through the whole file etc before advising...I can understand that but it would take at least a couple of hours to wade through it all. I'd prefer the Small Claims Court.
Our surveyor is also in the frame for the bill since he said that the discharge might go into the stream but at no time did he advise or draw my attention to the need for a permit if this was the case and also the demise of the permission in 2020.
