Extension - Floor Level Lower Than Main Drainage

[gordon.hunter]

Hi all

It’s looking like the floor level of an extension is lower than main drainage of property.

I would like to avoid Saniflo.

Is there any other options.

We live in a town rather the countryside and so have neighbouring properties.

Photos might be a good idea. You might be able to add underground drainage and a stub stack or even a Small soil and vent pipe.

Sounds like you need to look at a small package plant to hold and pump the waste up to a suitable point on the gravity sewer. Examples here: https://drainstore.com/pumping-stations-pumps/packaged-pumping-stations-and-pumps/
