Water company Permission [SELF-CERTIFICATION APPLICATION] to build over/ close to a public sewer

Danny_G

Hi the project is a private property, connecting a new drainage pipe to the existing private property drainage (not the neighbours) but our private property, and the method to notify the water company (Seven trent)

EDIT:
Here is what we doing 
On the front driveway (where cars are parked) a new drain is to be being installed underground (using a 150mm pipe), to take away the excessive rainwater (surface water) and this collection will be done with a new pipe, which will connect to a new drain chamber, which will have a new manhole on the top.  (so connecting a New pipe to the existing private surface water pipe, which is already underground)
these are All private pipes (our own).   but it then this current private pipe goes into and connects into the neighbours surface water piple, so becomes a 'public' drain.  so we will be building NEAR a public drain.  But then again, it is Not really near the public sewer.


When you apply to a water company  /( Seven Trent) to build a Private connection, 
you can  apply with an application form, where their water /sewer planning people come and have a look (I think)
or
 you can apply yourself using something called a  Self Certification application, where you fill out a simple questionaire, and send it online, with a fee. Seven Trents fee is £65

and the form says

Remember, this form is for:

• Works at single domestic property

• Involving pipes of 150mm diameter or less

this Self Certification application is a quick  way to apply for permission, to start your work to join your existing pipe to a new pipe (on your private property) - connecting to the Private sewer.

Does anyone have experience of this?
How many days does it take?

and as long as you tick all the boxes, then do they most likely accept your application, when you apply.?

The same can apply to other water companies, who offer Self Certification application.

Have you applied for this [Self Certification application] ? what was your experience?


Can this private  water drain connection be done without their notification, without telling them? or this can cause problems in the future? if so, what possible problems can arise in the future for keeping this a secret?
