Performance of Remote Wet Weather Treatment Facilities

Remote treatment facilities are often included as part of combined sewer overflow long term control plans to reduce overflows, provide treatment of overflows, capture first flush, and reduce peak wet weather flow rates in conveyance systems. Remote treatment often has the advantage of lower cost and less disruption to the community compared to alternatives such as increasing conveyance system capacity or adding storage through large tanks or deep tunnels. However actual data on performance can be difficult to find. This presentation will discuss recent improvements to remote unmanned treatment facilities at Rock Island. The new facilities capture first flush, provide the equivalent of primary clarification and disinfect any discharges. Performance factors including energy consumption, effluent water quality, and operations labor will be presented.
