Asbestos Cement Pipe Rehabilitation: How To Avoid …
Replacing or rehabilitating AC pipelines should be done before catastrophic failure occurs. Waiting too long can lead to an increased risk of contamination of potable water and increased cost of rehabilitation. The Safe Drinking Water Act (SDWA) has limited asbestos fiber content in drinking water to 7 million fibers per liter (MFL).
