490 <br />in location of the main depending on which side of the street you lived compared <br />491 <br />to the side the main was located in. <br />492 <br />493 <br />In response to questions of Member Gjerdingen, Mr. Schwartz advised that <br />494 <br />currently contractors work with property owners with lining technologies for <br />495 <br />sanitary sewers during a specific project; however, he clarified that for economies <br />496 <br />of cost, they needed 100% participation from homeowners from one manhole to <br />497 <br />the next, resulting in an approximate cost for homeowners of $3,000 for each <br />498 <br />lateral from the main to the property line using robotic equipment. Mr. Schwartz <br />499 <br />estimated that for an additional $1,000, barring collapsed pipes or other issues, <br />500 <br />this lining could gain the property owner an additional 50 plus years in life for <br />501 <br />their laterals. In comparison to the expected lifespan of a roadway, Mr. Schwartz <br />502 <br />confirmed that that was typically 50 years or more, deending on another set of <br />503 <br />variables. <br />504 <br />505 <br />If the goal is to make the sanitary sewer and water laterals last that same amount <br />506 <br />of time, Member Gjerdingen opined it was a benefit to do this. <br />507 <br />508 <br />In response to Chair Stenlund's concern ith compaction issues arvice lines <br />509 <br />compromising or creating structural issues with roads compromising rivate lines, <br />510 <br />Mr. Culver advised that generally compaction resulted from installation of a <br />511 <br />service line at the time a home was constructed and connected to the main, or <br />512 <br />when the sewer line was initially installed. Mr. Culver advised that the location <br />513 <br />of the laterals, or determining who was at fault or error was not always easy to <br />514 <br />define, since it could be both or either the City and private contractor working <br />515 <br />within the right-of-way. <br />516 <br />517 Member Felice asked if lining of older sewer lines could be offered to <br />518 homeowners when the City was going in to redo sewer lines. <br />519 <br />520 4Mr. Schwartz esponded that the question also came up at the City Council level, <br />521 and clarified that there are two different lining processes for the main and the <br />522 laterals, which can be followed one after the other, but typically done during the <br />523 same timeframe. Mr. Schwartz advised that typically the main was lined followed <br />524 by lining of laterals. However, Mr. Schwartz reiterated that, under current policy, <br />525 laterals can only be done when homeowners are interested in doing so and if the <br />526 contractor was only doing 1 or 2 from manhole to manhole, they estimated their <br />527 cost would escalate to approximately $8,000 each due to that economy of scale. <br />528 <br />529 Member Cihacek noted that an option under a new policy could be for <br />530 homeowners to pay upfront in an escrow account or in increments amortized over <br />531 a certain timeframe to ensure funding is available. However, Member Cihacek <br />532 noted one issue is that the City could not determine which pipes would fail first <br />533 without having the information on pipe size and type loaded in its recordkeeping <br />534 system. <br />Page 12 of 17 <br />
