Cap with Infiltration <br /> The Union Street sewer rehabilitation design employs trenchless construction methods that <br /> include lining manholes and installing a cured-in-place lining the length of the sewer. The lining <br /> alternative recommended in the design is Cured In Place Pipe(CIPP). <br /> CIPP lining can be used on nearly any size of pipe. The process involves inflating a felt tube <br /> soaked with resin into the sewer pipe. Once the felt tube has been inflated throughout the length <br /> of pipe, heated water or steam fills the tube and is kept at a high temperature until the resin cures <br /> and hardens to form a new pipe inside of the deteriorated pipe. <br /> Figure 7. Heat curing of felt tube liner. Figure 8. Inserting the liner into the pipe. <br /> The CIPP process has been used with good results by the City in many locations. Figures 8 and <br /> 9 above show cured-in-place lining installation work completed on past City projects. <br /> Page 18 <br />
