Trans Mountain Pipeline Fiddle River Hazard Remediation

This project entails a combination of two undertakings, including constructing a berm on and from the deposited gravels in the old gravel pit and armouring the 24-inch pipeline right-of-way at the overflow. In order to construct the berm, the flow of water entering the old gravel pit will be diverted into the adjacent active channel of the Fiddle River. Two rows of gravel filled mega bags will be placed via helicopter in the channel presently flowing in the old gravel pit. Armouring of the pipeline right-of-way may entail dewatering of the right-of-way area. If overflow is still occurring in the work area at the time of construction, a dam will be used to restrict flow into the work area and water will be pumped around the site. A fish salvage will be undertaken from the local pool of water at the right-of-way. Access for the construction of the berm will be downstream of the Highway 16 bridge on the Fiddle River and west towards the northeast to the gravel pit along the old access to the pit. Access to the work area for armouring of the pipeline will be via the existing right-of-of way from the west.
