Refilling. Only after the sewers and other related work has been laid, installed and proven after testing to be water tight, the trench and other excavations shall be refilled. Utmost care shall be taken in doing this, so that no damage shall be caused to the sewer and other permanent works. The filling in the trenches up to 75cms above the crown of the sewer and other lines shall consists of the finest selected sand and related materials placed carefully in 15cms layers and flooded to consolidation. After this layer has been laid the trench and other excavation shall be refilled carefully in 15cms layers with materials taken from the excavation, each layer being compacted to assist in the consolidation unless the Engineer shall otherwise direct.
