Replace low manhole cover in patio with slab inset and re-lay acco drain channel around edge

Added 10th February, 2023: -------------------------- Replace low manhole cover in patio with slab inset type and re-lay acco drain channel around edge. The current manhole cover is set down approx mm from patio level so will need building up and replacing with new cover with slabs inset. We are also looking to extend the acco channel around the edge of the patio to tidy it around the soil pipe and drain.
