is it as simple as digging and lining a trench to the manhole and filling with gravel?
I think it’s illegal to divert ground water into a sewer. Your water company won;t like it very much.
Also, you need building regs for any new work connecting to an existing drain now. The council won’t like it very much.
You’ll possibly end up causing the sewers to overflow and cause pollution. The Environment Agency won’t like it very much.
This is correct answer, do not divert a spring into the sewer, it’ll cause a lot of problems, your lateral conection will only be a small bore pipe (typically 100mm) it will cause you problems and your neighbours if it is a shared drain, sewer flooding is not fun, trust me, I’ve been out to more than my fair share of flooded houses.
Any ‘new’ connection to the sewer would need to have a formal application made (typical application cost c£500-£1000 depending on company) if this is not gained you can be forced to remove the connection at your own cost.
