Above the granular backfill content, the authentic dug materials can be used to entirely backfill the trench. This should be compacted in 300mm layers. Be certain not use hefty compactors until there is at the very least 300mm of protect. Light-weight vibratory tampers could be utilised sensibly to assist with the compaction.
You will need to protect any portion of the drain method that is less than 600mm underneath a garden. This is simply because of possible damage from backyard pursuits and gardening instruments.

As a common rule, any adjust in path of the pipework must be provided with an inspection chamber to permit rodding accessibility. This will also implement to alterations in gradient, all drain junctions that are inaccessible to a established of drain rods, changes in pipe diameter and at the head of each operate of drain.
