Service life can be increased by using effective bondedcoatings as well as polyethylene encasement and cathodic protection. Theindustry experience of users, engineers, coaters, and manufacturers demonstrates that are good enough even in harsh environments. Experimental evaluationsrevealed from various water utilities showed that demonstrates sufficient servicelife and lower maintained costs against alternatives. Now applymodern pipe management systems. Before application several soil parameters such as resistivity/conductivity, moisture content, chloride and sulphide ionsconcentration, redox potential, presence of landfill, fly ash, coal, peat, mine waste,are searched. After that, if necessary required are taken before burying the pipes.

Keywords: Harsh Environments, Corrosion Protection, polyethylene, ductile cast iron.
