ABSTRACT

Sewage Infrastructure Corrosion Costs about $1.1 Billion / Year . This cost translates to about $50.00/ person /
year.

Recent advancements in microbial control use what nature has evolved , to remove biofilm and biofilm sediment
complexes from the sewer pipes. This removes the cause of sewage odour generation and thus infrastructure
corrosion.

Any reduction in odorous sulfides arriving at the sewage treatment plant will reduce the oxygen demand required to
convert sulfides to sulfates. In the case of extended aeration plants, this will save energy and thus greenhouse
gas emissions. In addition, removing biofilm and sediments from the sewer pipes, will improve their hydraulic
efficiency, reduce pumping energy and thus greenhouse gas emissions.
