Carry The Kettle First Nation Lagoon Expansion

The Proposed Project

A new HDPE DR 11 Sewage Force main to be installed in the ditch of the lagoon access road parallel to the existing sewage force main. New Storage 66,000 Cubic Metres storage cell for the facultative lagoon. New 1.5 Ha Primary Cell for the Facultative Lagoon
New Wet Dry Style Sewage Pumping Station.

During construction top soil will be stripped, the ground will be excavated and lagoon berms will be constructed around the excavation. The lagoon will be lined with a HDPE liner to prevent effluent from seeping into the ground. Weeping tile will be installed under the liner. 300mm of sand will be installed on top of the liner for puncture protection. Topsoil will be replaced on the berms and seeded. Concrete effluent transfer structures will be installed for the new lagoon cells.

A new sewage forcemain will be installed via open trenching down the ditch of an existing roadway next to the existing sewage force main. Top soil will be stripped, replaced and seeded upon completion.

The new sewage pumping station will be excavated near the existing sewage pumping station to tie-into existing gravity sewer infrastructure. The structure will be approximately 6-7 meters in depth and will be comprised of concrete walls. The area will be excavated, temporary formwork for the walls will be constructed, rebar placed and concrete poured. Upon completion of the foundation a small 750 square foot building will be constructed housing a backup generator, motor control center and pumping equipment.

General construction waste, wood, plastics, and access materials will be disposed of off site properly as per provincial laws and regulations. Any access soils and earthworks will be used in the thickening of the lagoon berms.
