Existing 12,900 cu.m. primary lagoon cell being expanded with an additional 146,252 cu.m. lagoon storage cell. Approx. 5,750 lin.m. of new 150mm dia. DR17 sewage force main from SPS no.2 to the east lagoon. Approx. 500 lin.m. of new 200mm dia. PVC gravity sewer main from SPS no.1 to SPS no.2. The east lagoon expansion will consist of flagging of the existing forested area to indicate clearing extents, tree clearing within the extents marked by the Engineer, topsoil stripping, earthwork excavation/fill to construct the new lagoon cells, placement of 600mm thick compacted clay liner, topsoil replacement, seeding and erosion protection. New forcemain installation to convey sewage from the west core area to the east lagoon. Decommissioning of the existing west lagoon upon completion of the east lagoon expansion.
