A key part of the upgrade effort was focused on the elimination of one‐ton chlorine gas cylinders at Nunes and 150‐lb pressurized gas cylinders at Denniston. Aside from the obvious improvements in operator and community safety (liquid containment of 0.8% sodium hypochlorite leak is far easier to manage than a chlorine gas leak), the cost savings related to the risk management plan and emergency scrubber maintenance made sense. CCWD undertook an effort to interview and analyze the on‐site hypochlorite generation (OSHG) offerings from the four largest suppliers in North America. Weighing heavily in the analysis were the related issues of dependability and reliability. As Sean Donovan, Treatment Plant Supervisor put it, “We are the vanguard of public health. We don’t get a day off, so we have to have reliable equipment”. CCWD ultimately chose the Process Solutions, Inc. Microclor® OSHG system for both plants with Denniston installing a 40 pound‐per‐day (pounds of equivalent chlorine gas) first and Nunes utilizing a 100 pound‐per‐day system about a year later.
