Construction of a New Installation - Canadian Forces Base Bagotville

The Department of National Defence (DND) has proposed a project which involves the construction of a service building which will include six aircraft bays, offices, a kitchen, conference and relaxation rooms, dormitories, a gymnasium and washrooms.

The service building will cover an approximate 6000 square meter area and will be served by utility services (drinking water, electricity, telecommunications). New facilities will include several related infrastructures: a protective wall, an aircraft apron, a taxiway, a fence, a main gate (B613) and a bypass road.

However, given that the facilities location does not allow connection to the city sewer system, the wastewater will be routed to an independent septic system allowing the wastewater treatment by ground infiltration composed of septic tank with a leaching field.

In addition, the hangars industrial vocation requires that the water from floor washing is not brought into the wastewater treatment system, which is not adapted to the situation. Consequently, a watertight basin is therefore planned to directly collect this water which will have to be drained and managed according to the regulations. These same watertight tanks will also be used to recover foam and water from the building fire protection system. Actuator valves will divert these discharges to tanks instead of the septic tank.

Finally, deforestation, soil excavation including off-site disposal and backfill material import will be necessary for the building construction and the various related infrastructures attached to it.
