in location of the main depending on which side of the street you lived compared <br /> to the side the main was located in. <br /> In response to questions of Member Gjerdingen, Mr. Schwartz advised that <br /> currently contractors work with property owners with lining technologies for <br /> sanitary sewers during a specific project; however, he clarified that for economies <br /> of cost, they needed 100%participation from homeowners from one manhole to <br /> the next, resulting in an approximate cost for homeowners of$3,000 for each <br /> lateral from the main to the property line using robotic equipment. Mr. Schwartz <br /> estimated that for an additional $1,000, barring collapsed pipes or other issues, <br /> this lining could gain the property owner an additional 50 plus years in life for <br /> their laterals. In comparison to the expected lifespan of a roadway, Mr. Schwartz <br /> confirmed that that was typically 50 years or more, depending on another set of <br /> variables. <br /> If the goal is to make the sanitary sewer and water laterals last that same amount <br /> of time, Member Gjerdingen opined it was a benefit to do this. <br /> In response to Chair Stenlund's concerns with compaction issues and service lines <br /> compromising or creating structural issues with roads compromising private lines, <br /> Mr. Culver advised that generally compaction resulted from installation of a <br /> service line at the time a home was constructed and connected to the main, or <br /> when the sewer line was initially installed. Mr. Culver advised that the location <br /> of the laterals, or determining who was at fault or error was not always easy to <br /> define, since it could be both or either the City and private contractor working <br /> within the right-of-way. <br /> Member Felice asked if lining of older sewer lines could be offered to <br /> homeowners when the City was going in to redo sewer lines. <br /> Mr. Schwartz responded that the question also came up at the City Council level, <br /> and clarified that there are two different lining processes for the main and the <br /> laterals, which can be followed one after the other, but typically done during the <br /> same timeframe. Mr. Schwartz advised that typically the main was lined followed <br /> by lining of laterals. However, Mr. Schwartz reiterated that, under current policy, <br /> laterals can only be done when homeowners are interested in doing so and if the <br /> contractor was only doing 1 or 2 from manhole to manhole, they estimated their <br /> cost would escalate to approximately $8,000 each due to that economy of scale. <br /> Member Cihacek noted that an option under a new policy could be for <br /> homeowners to pay upfront in an escrow account or in increments amortized over <br /> a certain timeframe to ensure funding is available. However, Member Cihacek <br /> noted one issue is that the City could not determine which pipes would fail first <br /> without having the information on pipe size and type loaded in its recordkeeping <br /> system. <br /> Page 12 of 17 <br />
