What does this mean for water utilities?
Given the many known and unknown risks of vinyl chloride and PVC products, the long-term future of PVC pipes is uncertain. After the U.S. EPA completes its risk evaluation, there could be restrictions or even an outright ban on the use of PVC pipes in drinking water systems. Additional problems with PVC pipes may also be discovered in this process. Drinking water utilities should examine the risks already associated with PVC and the potential for action from the EPA and consider the practicality of switching to safer pipe materials.
Here are some steps they might take:
Evaluate alternative materials:
Water utilities regularly make material decisions as part of their infrastructure planning. Through their existing design and purchasing processes, they can prioritize durable, proven options such as Ductile iron. Incorporating these materials into capital planning can support long-term reliability and provide added confidence by avoiding certain known and potential risk considerations associated with PVC. Water utilities should consider pausing the use of PVC during EPA’s ongoing review.
Engage stakeholders:
As part of regular communications, utilities should share information about EPA’s ongoing review of PVC with governing boards, engineers, and community stakeholders. This may include discussing the regulatory considerations and potential risk factors associated with continued and future use of PVC.
Develop a transition plan:
During EPA’s ongoing review, utilities should consider beginning forward-looking planning discussions so that any material adjustments can be incorporated seamlessly into upcoming projects. Given the risk considerations currently associated with PVC, early coordination allows updates to align easily with existing project schedules.
Transitioning from PVC water mains to other proven materials, such as Ductile iron pipe, is a straightforward process that provides communities with greater confidence in the long-term safety and reliability of their water infrastructure.
