If anyone has ever had a company drill a borehole soakaway can you share your experiences? Wouldn't they just be finding water at certain depths?   I have approached a few drilling companies and received such a mixed bag of opinions which go like this:   1) X geotechnical company tell me a no, a borehole soakaway wouldn't work on the site 2) As above and they'd struggle to see it working as we're on Mercia mudstone 3) X Services said they'd need a hydrologist to do
