can someone tell me what material is required for installing sewer lines to addition toilet

The question is rather vague so I will attempt to offer some general information that may prove helpful.

Technically speaking a "House Sewer" line is an underground line running from the structure to a septic tank or municipal sewer main.

Typically the house sewer line is run with Cast Iron (no-hub), PVC sched. 40 DWV grade, ABS sched. 40 or vitrified clay pipe, although the International Residential Code also lists DWV grade copper, Copper types M,L & K.

Some local jurisdictions will also allow PVC or ABS sched 30 and SDR 35 (size dimension ratio) pipe .

Sanitary drainage lines inside a structure are defined as DWV (Drain, Waste & Vent lines). Principally they are run with cast iron (no-hub), SCHED 40 PVC DWV grade, Sched. 40 ABS DWV grade, (SDR pipe may not be used inside a structure) check your local code as some jurisdictions require cast iron.

Although very seldom used today, the code also lists DWV grade copper, Copper types k,L, &M, and galvanized steel.

A word of caution. when using plastic pipe (PVC or ABS) all pipe and fittings MUST BE made of the same material. The codes prohibit glueing dissimilar types of pipe or fittings together.

Just a touch-up on lazypus post if I may, make sure if you do use any plastic pipe that will go horizontal and be underground make sure it is sch 40 and not "Foam Core". Foam core is less expensive but is intended for interior, non pressure use only, if it is burried underground a car running over it may in time crush the pipe where as the sch40 will withstand the cars weight. Also note that if you have to run the pipe under the footing of the house you should install a short piece of 6" sch40 pvc as a sleeve, then run the sewer line through it this way if the house settles at all, it will not crush the pipe. The sleve only needs to extend about 6" inside and outside the footing. To seal the ends, I usualy just insert some loose insulation around the sewer line then back fill.
