Abstract:A large southern municipality's collection system continues to increase in population and expand in coverage area. Finances for SCADA improvements are limited, and the local EPA is breathing down their neck about recent spills. Twenty seven of the over 100 sites they need to monitor represent a disproportionately large cost of the proposed system because they are in outlying areas or on small to medium sized lift stations. Fully integrating cellular collected and web delivered SCADA into the traditional SCADA system saved millions of dollars for one city and provided more timely alarm and status information than the original plan.
