This MRWA specification sets out the principle requirements for the backfill and compaction of soils in excavations associated with the construction of water supply and sewerage assets. This specification refers to the trenchfill zone and not the embedment zone (for details of embedment zone requirements, refer to the MRWA Edition of the WSAA Water Supply and Sewerage Codes). This specification also applies to fill associated with assets constructed by tunnels, drives, shafts, bores and other trenchless technologies. Deep compressible clays (Coode Island Silt) are outside the scope of this specification.
