T H E C I T Y O F S T E R L I N G H E I G H T S, a suburb of Detroit , Michigan — pop - ulation 132,000 — has undertaken what it calls The Recreating Recre- ation initiative to leverage existing natural resource assets to create a City that provides its residents with year- round recreational opportunities. One of those initiatives, an outdoor splash pad, or water park, opened earlier this summer with great excitement from the City 's residents. The splash pad was built on a closed-loop system, meaning that the water €lows through the sprinklers, is looped back to be €iltered, and is then redistributed through the sprinklers where the cycle continues. Shortly after the opening of this popular at- traction, City of€icials recognized that the splash pad was losing an es- timated 8,000 gallons of water every day. While some depletion of water is to be expected via naturally-occurring evaporation and by residents cooling off and enjoying the summer activi- ties, this amount was extreme. To pro - tect its natural resources the City took immediate action. City of€icials called on Corby Ener- gy Ser vices Inc ., a D etroit - area con - tractor, to assess and quickly address the excessive loss of water and dirt that was leaching in to the system . Corby Energy completed an init ial televising and invest igat ion of the 10-in . return drain . After review, it was determined that the pipe could not be repaired by excavat ion , as the return line was under the newly poured concrete pad. With a special - ty in the construct ion and rehabili- tat ion of mainline systems using the cured-in -place (CIPP) method, Corby Energy project manager Josh Free - man realized this project was unique because there was only one point of access to the pipe. He determined that a " lateral blind shot " was need- ed in order to rehabilitate the failed water line and he needed to partner with another g roup to tackle the re - habilitat ion of this unusual project . He called MaxLiner USA technical ser vices manager Chad Miller for a recommendat ion . " It was clear to me that this job had to be done quickly, and during a time that was non-disruptive to the op - eration of the water park," said Miller. " Using CIPP technology for this job was a good call by Corby Energy Ser- vices because it allowed the contrac- tor to get in to do the work overnight when the splash pad was closed down, minimizing disruption and allowing the City to open the facility up the fol - lowing morning ." Miller and Freeman reached out to a familiar partner and local contractor, John Curtis, from InnovaLiner Inc., lo - cated just across the Michigan border in Monclova, Ohio. " This was truly a team effort ," continued Miller. " The work had to be done fast and the high- exposure location made a quality in- stallation critical , so the InnovaLiner and Corby crews came to the jobsite packing all of the equipment and ma- terials they needed. This included the camera, liner, resin, clear calibration tube and heater to cure the liner. I live in Michigan about an hour north of the jobsite, so I took this opportu- nity to provide the InnovaLiner crew with some additional on- site training . I loaded up my truck with the Max- LinerGun and was there with the crew around 7:30 p.m., on stand-by until the park closed at 9 p.m. and we could begin the work." The aluminum MaxLinerGun is a compact inversion unit for lining 2- to 12-in. diameter pipes and is best suited for residential and industrial drains in horizontal or vertical appli- cations. " I knew the MaxLiner system was well - suited to easily transport in tight 52 T R E N C H L E S S T EC H N O LO GY S E P T E M B E R 2018 Lateral Lining Saves Water and Summertime Fun By Heidi O'Leska
