Dear Imbayyah,
The piping solution will of course depend on the network spécifications (size, nominal pressure, flow rate, design, etc.) and the availability of solutions. In terms of environmental impact and long-term reliability, plastic materials should be favoured.
To answer your question, the best material for water supply is without any doubt bi-oriented PVC, or PVC-O, also called OPVC. The production of PVC-O pipes consists in a 2-step (extrusion and orientiation) process of classical PVC-U resin. This kind of technology is widely used in Australia, North-America, The Netherlands and France amongst others.
Please let me know if you need more information. You can also check this link:
