Adding to existing brick inspection chamber

[BathDIY]

Is it OK to add to an existing brick built inspection chamber?

Can you simply stitch drill a hole and insert the 110mm plastic pipe?

You need to notify Building Control of your intentions, and obtain approval from your water authority

Few variables in this situation, firstly, method depends on size of chamber. Shouldn't be any weight put on the pipe, if a deep chamber then brickwork needs to be suitable supported above the pipe entry. Foul drainage will need to discharge into the channel, into direction of flow to avoid fouling of the benching opposite. As Muggles has said, Building Control will need to be informed.

Whether the Water Co. need to be informed as well as B.C. depends on what goes through the said chamber. If it is just your property using it, then the drain is private and of no concern to the Water Co. However, if one or more other properties drainage runs through this chamber, then it is actually under the ownership of the Water Co. now, and they will need to give permission and guidance for any work carried out on or in their asset.

Thanks all.

Am assuming building control will inform me of what needs to be done RE pipe support etc?

Any idea of the cost getting bulding control etc. involved?

Not normally.
Generally you submit plans and they approve them. Building control is not a design service.
