Solidification of Storm Water Pond Sediment

Solidification of Storm Water Pond Sediment

The naturally occurring sediment in this storm water management pond had exceeded the pond's designed capacity. The regional conservation authority planned the remediation of this pond to involve the removal of this sediment. The volume of sediment to be removed was very large, thus the cost to transport and dispose of this wet muck would be very costly.

Drill Waste Management for Gas Distribution Upgrade

Drill Waste Management for Gas Distribution Upgrade

In 2015, a major Canadian natural gas distribution company had to perform construction operations to upgrade its existing distribution system. To mitigate the disturbance of the surface level roads and natural habitats, the proponent utilized horizontal directional drilling (HDD) technology. Twenty large bores (36" and 42") were planned for this project.

Enbridge Gas Distribution Pipeline Project

The Georgian Bay Pipeline Project was necessary to meet growing need for natural gas in that region. The new pipeline was 20 kilometers and 12” diameter. The route for the pipe included 30 road, rail and river crossings which would require horizontal directional drilling (HDD) to complete. Spent HDD fluids and cuttings are a regulated waste in Ontario and very costly to transport and dispose of. An estimated 250,000 gallons (940,000 litres) of spent drill mud would be in need of disposal.
