I <br /> Option 2. Cured In Place Pipe (CIPP): CIPP lining can be used on ne ly any size of pipe. <br /> The process involves inflating a felt tube soaked with resin into the sewer pipe. <br /> Once the felt tube has been inflated throughout the length of pipe, heated water or <br /> steam fills the tube and is kept at a high temperature until the resin cures and <br /> hardens to form a new pipe inside of the deteriorated pipe. <br /> Figure 9. Heat curing of felt tube liner. Figure 10. Inserting the lin r into the pipe. <br /> The CIPP process has been used with good results by the City in many locations. <br /> Figures 9 and 10 above show cured-in-place lining installatior work completed on <br /> past City projects. <br /> i <br /> I <br /> Page 8 <br />
