Chair DeBenedet opined that this is one project needing recondition of all pipes in <br />the system that are clay or reinforced concrete sewer mains; and with more than <br />100 miles of pipe, it would take a minimum of twenty (20) years to accomplish <br />the task. <br />Mr. Schwartz estimated closer to thirty (30) years; but the City was only taking <br />the first twenty (20) years into consideration at this time. <br />Member Felice questioned the life expectancy of new materials and whether they <br />had been used long enough to know an accurate history on their lives. <br />different types of materials and their life <br />providing a vast difference in predicted 1 <br />historically proven at this time. <br />year range before completion of the <br />Chair DeBenedet opined f <br />backups that would increa <br />Chair DeBenedet noted th <br />3A provided a listing for all <br />with sewer lining material <br />; however, not <br />ve reached the 80- <br />-term CIP <br />ka�4es and infiltration or sewer <br />o major failures anticipated. <br />eement on life expectancy <br />�e ility of the service would <br />the capital replacement <br />cal issue with no public <br />'s infrastructure. <br />the Metropolitan Council was the <br />e, since lection of Sewer Availability Charges <br />their CIP program; however, their revenues had <br />with downturn in the economy and new buildings. <br />advised that they were shifting their CIP costs onto their <br />that, as sewer systems continue to age and leak more, that <br />overflow passed iiMo wastewater treatment plants; and as they couldn't treat it, <br />they were only able to partially treat that flow before it got to the river, creating <br />violations of environmental permitting requirements. Chair DeBenedet noted the <br />need to address that, as a society and from an environmental standpoint, before <br />that happened, and that could be accomplished by planning ahead. Chair <br />DeBenedet opined that the SAC charges were the best planning tool available, <br />allowing wastewater treatment plans to be installed to accommodate additional <br />capacity for new construction. However, if that new construction wasn't <br />happening, Chair DeBenedet noted that the treatment plan may have more useful <br />years, but lacked revenue to support its operations. <br />Page 6 of 18 <br />
