    "Incorporate the manhole in the new floor using a recessed airtight cover screed it in and latex it or divert it out the extension then back in further along if you have space to do so"

    "Need to see an aerial plan of the property with existing drainage run and the outline of proposed extension.

    Strict regulations apply to these works plus it all depends on the local area water undertakings regarding what they will and will not allow. There is also the consideration of a shared run with adjoining properties as you say you are the end property."

    "Hi usually within this situation the manhole need to moved outside of the extension and the drain line diverted back onto the original drain line. If you have building control involved they should should also tell you this. If by any chance you have got the area an internal cover can be installed but access panel will be needed just in case of a blockage etc.

    Hope this helps
