High density Polyethylene (HDPE) pipes are mainly used in industry and public works. Since HDPE pipes introduced into market place is later than the other plastic pipes, the market of these pipes is still limited. However, the chemical resistance and durability of HDPE are better than other pipe materials. It is expected that HDPE pipes have a good potential to increase its sales in the near future. The objective of this thesis study is to investigate the feasibility to use HDPE pipes in drinking water and sewer lines. The construction procedure, cost analysis, and materials specifications for HDPE, PVC, and ABS pipes are discussed. The advantages and disadvantages of these pipes are compared. Two case studies are used for cost comparison analysis. The results of the study indicated that HDPE pipe is lighter than other plastic pipes and has better chemical resistibility. However, the material and construction costs are more than other systems.
