Study Shows Municipal Pipe-Repair Method Appears to Emit Hazardous Elements

When municipalities have to repair their pipes, they have two basic options. They can absorb days or weeks of disruption as the existing pipe is yanked from the ground and a large work crew is brought in to install a replacement. Or they can opt for a cheaper, 40-year old technology, that allows the pipe to be fixed from the inside – often in less than a day.

As Indiana Public Broadcasting’s Stan Jastrzebski reports, there is a second method, called “cured in place pipe,” or CIPP.  CIPP has been the subject of years of study by a Purdue University professor who’s published a research paper, showing that while the monetary costs are less, the health risks appear greater.
