Biigtigong Nishnaabeg Water Treatment System Project

During the design phase, activities will include site topographic survey and geotechnical investigation. Construction activities will include site clearing and grading; building of new water treatment facility; construction of access roads/driveways; installation of infrastructure servicing components (watermains, etc.); and restoration of affected areas. Operation activities should not change from existing activities. Watermains will be installed using a combination of open cut and trenchless methods. The following is a summary of site works items associated with the construction of the new infrastructure:
• General site grading (cutting/filling);
• Horizonal Directional Drilling;
• Excavation for water treatment system (rock and earth);
• Excavation for below grade concrete sub-structures; and
• Drainage swales and ditches.

The proposed facility will have poured reinforced concrete floor slabs, and concrete block walls and insulation. During
operation, the treatment facility and distribution system will require general interior/exterior maintenance activities
and occasional repairs.

The waste generation anticipated from this project would be comprised of construction related wastes during the construction period. The Contractor will be required to follow environmental protection control measures written in the Contract Documents. There is the potential for liquid waste generator as a result of spills. The likelihood of this is small and to mitigate the possible impacts, refueling of equipment and fuel storage (if conducted on-site) should be conducted in designated areas with spill protection. Construction activities could generate a small amount of gaseous waste from construction equipment exhaust and an increased amount of dust in the air as a result of rock excavation and blasting. Vehicles and equipment should be in good repair, equipped with emission controls, as applicable, and operated within regulatory requirements to mitigate this. Water would be used to minimize dust generation. Construction activities could also generate solid waste from packaging, cut off ends, etc. The waste will be properly disposed of by either recycling or directing it to a proper waste disposal site.
