PVC pipe's non-corrosive nature and resistance to chemical attack also renders it non-reactive with drinking water. PVC pressure pipes do not adversely alter water quality. There are no corrosion by-products with PVC pipe. PVC water pipes have been tested extensively using aggressive waters to verify their safety advantage.
The challenge for those within the urban water profession is both to protect both water quality and the ecological health of urban waterways (Aplin 2002).
An Australian paper which looks at the impact of concrete pipes and PVC pipes on the chemistry of different water types and what changes were made to the quality of the water. The paper, Impact of concrete and PVC pipes on urban chemistry by PJ Davies, I.A Wright, O.J Jonasson and S.J Finlay
