Mount <br />INTEROFFICE MEMORANDUM <br />TO: VILLAGE MANAGER, MICHAEL E. JANONIS <br />FROM: WATER/SEWER SUPERINTENDENT <br />DATE: JULY 28, 2014 <br />SUBJ: BID RESULTS FOR 2014 COMBINED SEWER TELEVISING ($404,706.67) <br />BACKGROUND <br />In the current budget, funds have been allocated for combined sewer system repairs. These <br />repairs were identified during the Combined Sewer System Evaluation Study (CSSES) <br />completed in 2004. In total, the study identified almost $15 million worth of combined sewer <br />repair work. The work was further categorized and prioritized as follows: <br />• Approximately 8% of the pipes were in severe structural condition (Category 5). The <br />report recommended that repairs be completed within one (1) to two (2) years. The <br />estimated cost to repair sewers in this classification was $2,481,600. <br />• 10% were in poor structural condition (Category 4). Completed repairs were <br />recommended within the next three (3) to four (4) years. The estimated repair cost for <br />sewers in this classification was $2,547,600. <br />• 20% had moderate structural defects (Category 3) requiring rehabilitation within the next <br />five (5) to ten (10) years. The estimated repair cost for sewers in this classification was <br />$4,957,920. <br />• 34% had minor structural defects (Category 2) that did not require repairs. However, the <br />report recommended these pipes should be periodically re- examined to assure that <br />noted defects do not worsen. The estimated cost to repair these defects was <br />$4,158,000. <br />• 24% were in very good condition (Category 1). No discernable defects were observed. <br />No repairs were recommended. <br />To date, the bulk of the major defects (all of categories 5 and 4, with a large portion of category <br />3) have been corrected. The remaining lineal footage was identified in 2004 as being of low to <br />moderate risk (categories 1 to 3). <br />Mount Prospect Public Works Department <br />The funding mechanism for the above referenced combined sewer rehabilitation work has been <br />a $5 per month charge to each water /sewer customer; generating approximately $800,000 per <br />year. This fee was initiated in 2006 and is set to expire in 2016. <br />
