Edmonton’s 99 Avenue sanitary trunk, built in 1975, is 30 m below ground, tall
enough to walk in and serves 117,000+ customers – more than the population of
Red Deer. To allow rehabilitation and increase capacity, EPCOR and the project team
constructed a new 1.6 km bypass sewer. An innovative microtunnelling approach
minimized surface impact. The first use of specialized pre-lined concrete pipe in
Edmonton withstood large boulders and jacking forces of up to 1000 tonnes. The
final connection to the trunk was made under live flow conditions during the dead of
night. Rehabilitation is now under way.
JUDGES’ COMMENTS
Such projects often go unnoticed or are ignored because they are out of
sight and therefore out of mind. Yet they are highly complex to manage
given the high number of parties involved, risks, soil/weather conditions and
scheduling involved in making this project a success. SMA Consulting did a
superb job at connecting it all together. Impressive.
