Sewer pumps are part of the drainage system and help move sewage through the pipes over long distances and up hills (when gravity cannot be used).
Edmonton has 62 sanitary pumps and 17 storm water pumps.
Edmonton’s sanitary sewer pump stations clog up with grease and other debris an average of 20 times a year.
An estimated $700,000 in staff time is spent on cleaning clogged pumps. It takes a three-person crew from Utility Services about a half-day to clean a pump and the cost of a new pump is anywhere from $10,000 to $120,000 depending on the size.
