Groundwater

paso11

Hi

A few months ago I had some renovation work carried out at my home which involved digging in a new drain line and inspection chamber.

It seems that during this process, by loosening the soil we managed to unleash some groundwater as a few months later there is water bubbling up from the concrete (no, its not a leaking mains pipe or foul waste, definitely ground water)

Anyone know how to deal with this or who to call? I'm assuming i cant just divert it down a drain?

Thanks

Either you have caused a spring which will be your issue to resolve, or you have fractured a water pipe - by weight, compaction or ground movement. If so it depends who owns pipe - if yours it is your responsibility, if the Water Board own it they will sort it. But if you have damaged their pipe you may end up paying for the repairs.

Depending on where you are, it could be a funny time of year to be seeing ground water which wasn't present before. Certainly, in the south it's been dry for months, relative to normal rainfall. Oop norf, different story.

Springs do relocate themselves, so if it's one of those you'll need to divert it to the lowest point on your property, where it will then be someone else's problem!

But no, they won't let you send it down a drain these days.

Im in North West London. I've "temporarily" had to divert down the drains- (yes i know im not meant to but it was starting to spill over into my neighbors land so had to do something as an interim measure).

Would putting in a french drain system around my house work? I know that in addition to diverting the spring i also need to protect my foundations.

If it is a spring, where are going to divert the water to if you can't use the drain? How much water is this spring producing (litres/hour) ?

like a hosepipe with the tap 1/3 open- if that makes sense?
