Certifying rainwater collection products and systems

UL Solutions certifies rainwater catchment products, from roofing materials to cisterns, for potable use against the applicable requirements detailed in NSF International’s 61 and P151 standards. We can also test systems for nonpotable uses, such as watering nonconsumable plants or some washing/cleaning purposes.

Standards to ensure proper use and design of rainwater harvesting products

Rainwater harvesting is making a resurgence, aided by increased awareness of potable water availability, sustainability and new green building practices.

Green building rating systems, such as LEED, give buildings points for water conservation measures. Due to this resurgence, codes and standards have been created to help ensure proper use and design of these systems, and we can help you meet these standards.
