[vc_row][vc_column][vc_column_text]The North American Society of Trenchless Technology\u2019s (NASTT) annual No-Dig Show is the largest trenchless technology conference in North America, where underground infrastructure professionals come together to learn new techniques to repair and improve infrastructure. Murraysmith + Quincy\u2019s very own NASTT members, Brendan O\u2019Sullivan<\/a> and Rylee Archuleta<\/a>, presented on the Interlachen Sewer Rehabilitation Project completed for the City of Fairview, Oregon. In case you missed it, here are five takeaways that highlight unique solutions to this project\u2019s challenges.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]1. Interlachen Trunk<\/strong>[\/vc_column_text]
<\/div>[vc_column_text]The City of Fairview\u2019s Interlachen Trunk Sewer is a 12-inch diameter, concrete sanitary sewer system that runs through nearly 70 backyard easements along the shore of Fairview Lake. To extend the life of its system, the City decided to rehabilitate approximately 12,000 linear feet of pipe.[\/vc_column_text]
<\/div>[vc_single_image image=”8428″][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]2. Environmental and Cultural Permitting<\/strong>[\/vc_column_text]
<\/div>[vc_column_text]Because the project area was once the site of a large Multnomah Native American village called nic\u030ca\u0301q\u02b7li, any excavation along the Fairview Lake shoreline would trigger floodplain permitting and archeological investigation. This challenging situation meant that a trenchless rehabilitation method was the best solution.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]3. Ultra-Violet vs. Thermal Cured-In-Place-Pipe (CIPP)<\/strong>[\/vc_column_text]
<\/div>[vc_column_text]The constructability constraints along the Interlachen Trunk provided\u00a0the perfect opportunity for an innovative solution\u2014UV CIPP lining. The small construction footprint allowed contractors to work around landscaping with minimal impacts to homeowners.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”8425″][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”8419″]
<\/div>[vc_column_text]1: Interlachen Lane is very narrow in places. 2: Staged liner at the site. 3: Cable running from Interlachen Lane to backyard manhole.\u00a0<\/em>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]4. Barging onto Site<\/strong>[\/vc_column_text]
<\/div>[vc_column_text]Due to the difficult access of the lake shore manholes, some CIPP installation sites were staged and cured using a barge on Fairview Lake. The barges were loaded at a point with vehicle access, then floated to the project site.[\/vc_column_text]
<\/div>[vc_single_image image=”8421″][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/2″][vc_column_text]5. Successful Rehabilitation<\/strong>[\/vc_column_text]
<\/div>[vc_column_text]In the end, the Interlachen Trunk was successfully rehabilitated due to the many benefits of UV-cured CIPP. In addition to a smaller construction footprint than thermal, advantages of UV CIPP include minimal styrene emissions (less impact to residents), no discharge water to capture (less environmental risk), a stronger and thinner liner (less hydraulic impact), and less risk of excavation due to the ability to inspect and re-insert the liner prior to curing.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”8426″][\/vc_column][\/vc_row]\n<\/div>","protected":false},"excerpt":{"rendered":"
