After struggling with efficiency loss and increased cycle times at 3 of their wastewater pump stations, the Town of Cary contracted with CCI to undergo their first ever force main cleaning project. Before cleaning could commence, we had to install bypass connections at each station. These assemblies actually doubled as “pigging stations” which were required for the cleaning. The Progressive Pigging method was utilized to flush more than 15,000 LF of 6” & 8” force mains and combat the significant build-up in the lines. At one station alone, flow rates improved from 91 GPM before the cleaning to over 200 GPM after.
