Sir, As Carlos mentions below there is no specific rule in choosing the pipe material. It depends on availability and economics. Bear in mind the availability of this pipe material for operation and maintenance. Concrete pipe is brittle and fragile, heavy and hence need to be handled cautiously. It could have high operation costs. Concrete mixed with Asbestos Cement should not be used because on environmental and health impacts. Ductile iron pipes are the best but are costly. HDPE pipes are mid-way but need to be buried as sunlight (UV) would have an impact on it. I suggest that for the same pipe diameter you carry out a cost analysis on the available pipe materials in your village/country. Cost to include operation costs also.
