The Brew Cabin

Hi
I am in the process of digging foundations for a new extension.

We have encountered an old brick inspection chamber about 3 foot square that serves both my and the neighbours foul water.

The edge of the chamber would be about 2 inches into the foundation walling.

Will I have to replace the old chamber or is there a cunning plan you may be aware of, any suggestions would be gratefully accepted.

Thanks for an excellent website by the way.

There's 2 options, as I see it. You either build the chamber brickwork into the foundation walling, assuming your BCO agrees, or, possibly, he/she allows you to 'nobble' the chamber brickwork to accommodate the new wall.

The second option is to replace the IC with a new camber, possibly a Polypropylene model.

Most BCOs are reasonable bods, and will try to find the easiest, least costly solution, but without seeing the set-up for myself, I can't say which would be best. If you are having additional drainage installed, the new IC might be a better option, as it would allow you to have all your new connections without having to break into existing pipelines, or create junctions, rodding eyes, etc.

Have you discussed this with the BCO?
