� <br /> r � <br /> � <br /> COUNCIL COMMUNICATION FORM <br /> PURCHASING& INTERNAL SERVICES MEMORANDUM <br /> #06-64 <br /> October 17, 2006 <br /> TO: Honorable Mayor Osborne and City Council <br /> FROM: Steve G ity Manager <br /> Ron Neufel inancial Management Direc�or <br /> Deborah M. Perry, Purchasing Supervisora- <br /> SUBJECT: Purchase of Chlorine Dioxide Generator <br /> SUMMARY RECOMMENDATION: Staff recommends awarding contract to Siemens <br /> Water Technologies Corporation to furnish one (1) Millennium III C500-EC automatic <br /> two chemical chlorine dioxide generator. li <br /> BACKGROUND: The current chlorine dioxide generator was installed in 1988 and no � <br /> longer has� replacement parts available. It has deteriorated from the 24 hour, 7 day a <br /> week usage. The generator is not able to provide continuous operation due to its age. <br /> Chlorine dioxide is a mixture of chlorine and sodium chlorite. In order to maintain the <br /> correct percentage of mixture, the generator must be reliable in producing 99% of <br /> chlorine dioxide. <br /> The IEPA (Illinois Environmental Protection Agency) has mandated the continuous use <br /> of chlorine dioxide under the Safe Drinking Water Act for our facility. Chlorine dioxide <br /> is used to provide a higher disinfection level of virus and bacteria inactivation from the <br /> raw water. It is also used to reduce the formation of disinfection by-products in the <br /> drinking water. <br /> This is a sole source purchase. Siemens Water Technologies manufactures the chlorine <br /> dioxide generator. The original piping and external controls will be used with the new <br /> unit. This means there would be minimal downtime to install the new generator which <br /> would not impact IEPA regulations significantly. In addition, installing a similar chlorine <br /> dioxide generator does not require an IEPA operating permit. <br />
