Case studies of asbestos water pipe management practices

However, leaving asbestos pipe within the soil, either whole or in fragments, creates a potential legacy issue. In 2015 the Victorian Government released WorkSafe Guideline WSV1648/01/04.15 Asbestos-cement water pipe management. This guidance stated that leaving any asbestos waste underground may be a breach of environment protection regulations.

In summary. this study has demonstrated that asbestos cement pipe behaves much like other piping materials, except PVC, that are commonly used for distribution of drinking water. If aggressive water conditions exist, the pipe will corrode and deteriorate: if aggressive water conditions do not exist, the pipe will not corrode and deteriorate.

Asbestos in Water and Asbestos Cement Water Pipes — Safe ...

Jan 18, 2017  The asbestos cement (AC), or transite pipe, was first introduced in North America in 1929. AC pipe was a common choice for potable water main construction during the 1940s, 50s, and 60s. According to a 1977 Health and Welfare Canada report, “More than 99.9% of the asbestos fibre produced in Canada was chrysotile.”.
