When Fernandina Beach Utilities Department Director John Mandrick sat down to read the latest issue of Trenchless Technology, he was taken somewhat aback. There on page 68 of the October 2016 issue was his photo and the city logo. As he read on, Mandrick realized that his department’s work on rehabilitating manholes and pipes had been highlighted as a cost saving, practical way to extend the life of old manholes in the city’s sewer system. Mandrick realized that selling the City Commission on a $20M expansion to handle the increasing load on the sewage treatment plant would be a heavy lift, so he began investigating alternative solutions. In 2005, and with City Commission approval, he embarked on what was intended to be a 7-year program that utilized a spray applied liner for manhole rehabilitation work and cured-in-place pipe (CIPP) technology to seal leaky pipes. Savings were realized almost immediately. Mandrick reported that the relining cost totals about $3.77M. Energy savings were also achieved, and the existing plant lowered its carbon footprint of about half a million vehicle miles per year. And equally important, the ground water, once intruding into the sewer system, is now percolating into the groundwater table.
