Attention Pipeline Integrity Division;
A low-pressure system is bringing widespread rain to Alberta. General amounts of 20-40mm is expected for most of the province (except the Northwest corner). Due to this expected precipitation, the following advisories are in effect. Anyone situated close to the streams affected are advised to be cautious of the rising water levels. This is an internal notification to update you of current high flow conditions issued by Alberta Environment and Parks. High flow can lead to waterway bank disruption, erosion, sloughing or scour. When this occurs over or around a pipeline water crossing the chance of a depth of cover failure or pipeline exposure increases. Pipeline leakages can lead to high cost property damage and high impact environmental damage. If you require any depth of cover services or research into pipelines with potential problems, please let us know. Contact Derek Leiman (780-293-1810) or Katie Welter (306-834-4402).
Below is an update from Alberta Environment and Parks:
