In our Septic System Answer Man column in the June issue of Pumper, author Roger Machmeier wrote about concrete tank deterioration. In talking about the ongoing issue, Machmeier referenced the National Precast Concrete Association Best Practices Manual for Onsite Wastewater Systems. The NPCA notified us that the manual has been renamed, updated and is now available at this link: http://www.solutions.precast.org/pdfs/onsite_bpm.pdf

You can reach the NPCA with questions or comments at 1320 City Center Drive, Suite 200, Carmel, Ind. 46032; by phone at (800) 366-7731; and at the organization’s website, www.precast.org.
