• Scope of work: The maintenance department of EPCOR Water D&T handles all the repair work that requires an excavation. Most of the maintenance work we cover is within the City of Edmonton, though there is some work we cover out of town (ex: Edmonton International Airport). We will go over the number of valves, hydrants, service lines, and km’s of pipe we are in charge of maintaining, and the number and size of crews we have out in the field. As well touch on some of the other departments and some of the repair work they can do without requiring excavation.

• Pipe material: Cover the top 3 types of pipe material in the Edmonton distribution network and the challenges and hazards we face dealing with each one. Asbestos Cement pipe for example requires us to take many extra steps to work with and handle safely. Also touch on how much of the City of Edmonton’s distribution network has been replaced with PVC pipe.

• Hazards associated with underground excavation: Maintenance does over 1200 excavations a year. A large amount of these involve maneuvering our work around other utilities (Power, Gas Mains, Communications, etc.) One of the biggest hazards our crews face on a daily basis is the heavily saturated soil we work in. We will go over some of the shoring methods we use to safely get a worker down into a ditch with class C soil.

• Water Main Breaks: This is the bulk of the presentation. In 2018 we had over 340 water main breaks in the City of Edmonton. EPCOR Water has made a commitment to the customers in Edmonton to have the water back on in 24 hours due to a main break. We will cover from start to finish how our crews fix these breaks in a timely manner. Main points will be on how we diagnose the cause of the leaks quickly, the use of leak detection, our excavation procedures, and our repair methods.
