Again, Mr. Pasko emphasized the need for appropriate ordinance language to protect the <br /> municipality and its residents. <br /> Q & A <br /> During and after the presentation, Mr. Pasko responded to questions of the PWETC. <br /> Chair Stenlund noted that, overall, the lower laterals in Roseville were not typically a <br /> problem for I & I. <br /> Given the age of the community and its infrastructure, Mr. Pasko opined that this was <br /> most likely due to backfilling of pipes in rights-of-way done to a higher standard with <br /> inspection staff on-site than may be found in current construction efforts. Mr. Pasko <br /> noted that the other side of the laterals were usually more problematic outside that right- <br /> or-way line with private contractors being less diligent in packing soils. Mr. Pasko noted <br /> that this was problematic nationwide, with findings that the lower lateral is better <br /> compacted than the upper lateral as it related to I& I. <br /> Chair Stenlund noted that some mains were not under the road in Roseville, but may be <br /> located on one side or the right-of-way or the other, and affected homeowners <br /> accordingly for rehabilitation costs. Member Stenlund questioned if those situations <br /> would be redlined as good candidates to consider for lining sooner than later. <br /> Mr. Pasko responded that lining was paid for by the foot; and as an example, there were <br /> many situations where whether or not that lateral was on the short or long side, those <br /> homeowners on the short side got more of a bargain than those on the long side. Mr. <br /> Pasko noted that some communities stipulate that all property owners pay the same to <br /> equalize factors; but if not a lot of those situations, that was not taken into consideration <br /> beyond a unique situation. Mr. Pasko noted that there were many different ways for a <br /> community to approach that inequity. <br /> Chair Stenlund questioned problems with flows coming toward the lining and creating a <br /> plug. <br /> Mr. Pasko responded that there were not, and as an engineer, a pre-lining television <br /> inspection (after cleaning the line) was performed and if active I & I was found, it may be <br /> addressed with a plug, while tree roots were removed. After that, Mr. Pasko noted that <br /> the end cap was cut off and then inspected again, and if the problem or indication of a <br /> problem during installation was observed, it was removed and the process done again. <br /> Mr. Pasko advised that he uses a two-year inspection clause for lining contractors, <br /> requiring them to re-inspect and correct any problems on their own dime. While it varies <br /> with contractors, Mr. Pasko advised that the best lining contractors average 2% or less <br /> with problem areas. <br /> At the request of Chair Stenlund, Mr. Pasko advised that the liner has a built-in taper, <br /> with minimal identification loss, and while there may many roots and problems within <br /> the pipes, there was little problem or evidence of problems from flushable items getting <br /> Page 6 of 20 <br />
