Walkerton Tragedy

In May 2000, an outbreak of E. coli contamination occurred in the water system of Walkerton, Ontario. In the aftermath of the disaster and the ensuing reforms to water treatment, the OCWA was put in charge of the cleanup of the water supply system of the town. This included a complete flushing of all the pipes in Walkerton, including those located in every building in the town.
