soak away

[steve396010]

Thanks for your previous answers. We have now excuvated the site and found our soak away is 14ft x 5ft and about 4ft deep. The problem we now have is part of the 14ft wall with the soak away pipe in has colapsed. If we just fill with gravel and back fill the water will not soak away properly.Would it be easier to empty the soak away, build this wall back. dig the garden some more and put in a new pipe. Or just fill it in properly and start again further up the garden?
