Understanding Environmental Implications Of CIPP Rehab Technology

By Ed Kampbell, P.E. | April 2009 Vol. 64 No. 4

It is recommended that the VA DOT perform additional sampling, studies and evaluations of CIPP installations and their effect on the environment, using good sound engineering and testing principles. The VA DOT has a wonderful opportunity to provide the industry with a review of its installation practices and refine them as needed to preserve cost effective and environmentally effective usage. The Virginia Water Quality Standards state that “state waters . . . shall be free from substances . . . [that] interfere directly or indirectly with designated uses of such water or which are inimical or harmful to human, animal, plant or aquatic life.” Further, the standards state that “Effluents which tend to raise the temperature of the receiving water will also be controlled.” The additional studies should use these defined guidelines in the context of proper installations following good housekeeping practices to assess the true environmental implications of CIPP rehabilitation technology in culvert and storm sewer rehabilitation. In so doing, the industry is confident that they will conclude that the NASSCO recommendations given previously are in line with Virginia’s clean water requirements.
