Milestone successfully secured a contract with the City of Ottawa for the cleaning of accumulated sediment at the Clarke Bellinger Stormwater Control facility. This facility plays a crucial role in managing stormwater flow from an upstream urban area to prevent accelerated erosion along a nearby creek. The project primarily employed hydraulic (suction) dredging techniques for pond sediment removal, coupled with advanced sludge dewatering technology.
The primary challenge involved safeguarding the environment and minimizing erosion while implementing sludge dewatering technology. Additionally, once pond sediments were successfully dredged and dewatered for off-site shipment, a key hurdle was identifying a disposal facility with sufficient space.
