While nearly 70% of the world is covered by water, only 3% of it is fresh.  With the Earth’s growing population, access to fresh, safe water is a growing concern.

One ancient and low-impact technique for obtaining freshwater is rainwater harvesting, and this collection method is making a resurgence, aided by increased awareness of 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 UL can help you meet these standards.

UL is accredited in the U.S. and Canada to provide testing and certification to standards referenced by the published ARCSA/ASPE/ANSI 63 Rainwater Catchment Systems design standard, ARCSA/ASPE 78 Stormwater Harvesting System Design for Direct End-Use Applications, the Uniform Plumbing Code, and upcoming drafted design standards by CSA/ICC and IAPMO. Such standards include: IAPMO/ANSI Z1002, NSF/ANSI 42, NSF/ANSI 53, NSF/ANSI 61, NSF/ANSI 372, NSF P231 and NSF P151.

With UL, you have direct access to highly knowledgeable staff that will collaborate with your team from the beginning to guarantee the smoothest possible evaluation of your rainwater catchment systems.
