Hydrologics Technology Solved Issues With New Main Installations

New Jersey | 2015

​

New Jersey American Water purchased a Hydrologics truck unit back in 2015.  On our last day of crew training I received a call from Vince Monaco (Sr. Engineer NJAW), with a request to flush approx. two thousand feet of two sections of newly installed 8″ PVC water main (installed by a contractor); these newly installed mains had been flushed and supper chlorinated several times over the past 6 months, but kept failing the Bac-T testing.  The contractor was told that if it failed one more time, he would have to dig them up and replace all of the new main at his costs!  Hydrologics flushed the new mains (with only 1.0 ppm of chlorine residue) for about 30 minutes (we could hear sand and rocks exiting the main into our truck filters).  They took their post flushing Bac-T samples right from the Hydrologics sample taps; and two days later I received news that the samples were negative (they passed).  Our Zero Discharge Flushing technology saved the contractor over $250,000 and I didn’t even get a thanks!
