@Jack4 yes your last sketch proposal is better, at least an acceptable proposal assuming the levels work! Who is submitting the Build Over/Near Agreement to the Water Company? You or your architect?If you look on your water company's website you should be able to find all the criteria you need to adhere to, it's usually pretty clear. I wouldn't waste time trying to submit anything to the WC for advice, they will want a fee before they look at anything.
That's what I suggested at post 3. It will work provided you have enough fall. I did something worse some years ago as we had turn the line out from the back of the house to clear an existing conservatory (built over the chamber) and then come back on ourselves as the new extension was on the side as well as replacing the connie. Oh and there were separate foul & SW just to add to the fun.
Coincidentally, along the way, my client spoke to one of Anglian Water's who suggested something similar to what your "architect" came up with
You need a proper drawing to submit to the Water Company with falls and dimensions
The water company will give you their standard template. They won’t design the drains for you.
He needs to ask his designer to do his job properly. However, as it is all below ground stuff, there may have to be a wee bit of uncovering first.
