The Rockaway Valley Regional Sewerage Authority (RVRSA) has received periodic odor complaints from residents along the interceptor sewer for many years. The most frequent odor complaints have been in the downstream areas of the Town of Boonton around meter chamber BT–1 and meter chamber STP. The Authority undertook an investigation and internal inspection of the 13 mile long Interceptor Sewer in 2008. It was found that significant corrosion had occurred in the Interceptor sewer in The Town of Boonton, and at limited locations in The Township of Denville and The Borough of Rockaway. The corrosion is the result of the formation of hydrogen sulfide gas (H2S) in the sewers which is also a primary source of the odor. Rehabilitation of the interceptor sewer corrosion has been undertaken at costs in excess of 2,400,000. This paper will present the evaluation of the causes of the interceptor sewer odors and corrosion and present the results of a pilot preventative control program.
