Concrete Garage over sewer manhole

[chris52]

Hi Guys
A little help needed I want to have a concrete sectional garage build but there is a sewer manhole cover right in the middle of where I want to put it.So basically I would need to raise the manhole a touch and lay the conrete all around it.The manhole would still be accesible but only from within the garage. Would this be Ok or would I need to have it moved which is not an easy option due to lack of room around where the garage would stand.
Cheers Chris

Depends what it's for and whether you post lots of details on the internet so that you can be 'collared'

You will need to apply for build over permission, speak to local water company, you need their permission before building on or around their services. If you don't have permission to build over it you'll find issue when solicitors do searches if you want to sell it. However I don't think it would be a case of moving it. Take into consideration if it's a shared service (does you neighbour share this drain) as they will need to be involved then. Assuming it's the properies own drainage manhole before the main sewerage manhold access I can't see there being an issue when you contact them.

Personally for a sectional garage I'd just do it.

As soon as you ask a Utility Co. the default position is no and there are time delays and costs.

Be very wary of just doing it as solicitors carry out drainage searches and it will stop a house sale. You'd find yourself having to pull down the garage if you wanted to sell the place.

Are you sure that the manhole is for a sewer...?
I recently started an extension and a manhole ran very close to my foundations.
I enquired with the sewage company and they stated that the build over permission was only for pipes in excess of 250mm and that any "runs" that are passing near / under do not need build over permission as they are not owned or adopted by the water company

As above, just get on with it.

Thanks Guys for the input. I may have explained things a little wrong here as it's just a square metal drain cover about 2 feet by 1.5 feet and it is just the sewage waste from our house nobody else's house uses it.
Does this make a difference?

If it's just from yours, then it's simply your decision.

Not fully understanding your post but, like you, I'm currently building an extension and have had to submit a build over application for a sewer pipe which is 110mm and runs parallel, and approx 8' from the back of the house.
Your lucky if your water board has not adopted your sewer pipes as it all changed over in 2011

The actual sewage pipe is 'owned' by the water board now, so because I was building over it, I required their permission & had to pay for the privilege.

If it's just your own foul drainage then you'll be OK ... at the most put a double seal cover on to stop smells within the garage

Thanks for all the input sound like its a goer

If it's just from yours, then it's simply your decision.

To clarify generally (not aimed at this reply, but as good a one to quote as any ), your own drain (as you've described, it takes only your propery's waste) is your responsibility to maintain and clear.

But once a drain has more than one property draining in to it, then the water company are responsible for maintaining it (and they would be interested in your building plans, in this case, to ensure access for clearing and maintenance if needed).

Some friends were having a garage built, which included raising the level of their drive - and a shared drain runs past the back of the properties (including theirs) and they have a manhole for said drain whose collar & cover would need to be raised to suit the new drive...

Yorkshire Water wanted in the region of £350 to be involved then ultimately to sign off the work to raise the manhole collar and cover! As this was linked to planning permission and eventually signing off the whole building, it can't be avoided.

As such, consider yourself lucky (unless the drain collapses in future, in which case hopefully it is insured ) not to have to pay the water company for their involvement .

While your on. Enlarge the manhole down the middle of the garage so it can be used as a pit. 😊
