Water Jetting
Sleeving, or relining. It depends on the type of application.
Orange color coded "pipe" is for telecommunication, alarm or signal lines, cables, or conduit. Orange colored PEX water pipe is a plastic pipe suitable for hot water lines. "Orangeburg" sewer pipe (not orange in color) was an inexpensive sewer pipe made of a wood pulp and pitch composite, it does not last very long and often fails catastrophically requiring expensive repairs.
The purpose of a sewer pipe is to collect waste from drains and peoples homes and transport it through the sewer system to the sewer plant. There it is treated and the water is recycled.

No. You vent air from a sewer line.
That depends alot on your location and what codes your jurisdiction has adopted. From the 2006 International Plumbing Code, "water service pipe and the building sewer SHALL be separated by 5 feet of undisturbed or compacted earth." There are exceptions, 1. "the required separation distance shall not apply where the bottom of the water service pipe within 5 feet of the sewer is a minimum of 12 inches above the top of the highest point of the sewer and the pipe materials conform to Table 702.3. 2. water service pipe is permitted to be located in the same trench with a building sewer, provided such a sewer is constructed of materials listed in Table 702.3. 3. the required separation distance shall not apply where a water service pipe crosses a sewer pipe, provided the water service pipe is sleeved to at least 5 feet horizontally from the sewer pipe center-line on both sides of such crossing with pipe materials listed in Table 605.3, 702.2, or 702.3." So, no, there is no minimum separation IF the materials you are using bear the correct ASTM #. (Your building sewer pipe will probably have ASTM F 891 stamped on it.)
