Standards for Rainwater Collection

water-321524_640The Rainwater collection industry is rapidly becoming more accepted, consumers are becoming more aware of water shortages, quality of water, and increasing costs of operations of a centralized water system are being passed onto the customer. Many are turning to a supplementary source of water, whether from a simple rain barrel, for small irrigation needs or a large-scale sustainable system for whole-house demands. The industry itself is changing and becoming more complex. States and counties throughout the US are witnessing such a rapid growth in interest of rainwater collection, many are struggling with regulations and standards to ensure public safety. In addition, increased demand is beginning to outpace the supply of available, qualified RWC system designers and installers. Without proper regulations standards, improper designs and installations by unqualified persons can lead to underperforming or even dangerous systems.

Without quality information and education, governmental intervention can lead to laws that do nothing to protect the consumer and the industry itself. Therefore the American Rainwater Catchment Systems Association (ARCSA) is the leader in education and information about RWC. The American Society of Plumbing Engineers, (ASPE) develops plumbing and design standards through a consensus of a standards development process in accordance with the American National Standards Institute, (ANSI). The Plumbing Engineering Standards are designed to provide accurate and authoritative information for design and specification of plumbing systems.

ARCSA/ASPE/ANSI63-2013: Rainwater Catchment Systems Standard was approved by the American National Standards Institute on Nov. 14, 2013 and was developed by a joint effort and sponsorship support from the International Association of Plumbing and Mechanical Officials (IAPMO) and the National Science Foundation (NSF) International. The purpose of this standard is to assist engineers, designers, plumbers, builders/developers, local government, and end users in safely implementing a rainwater collection system. This standard is intended for application to new rainwater catchment installations, as well as alterations, maintenance, and repairs to existing systems.

ARCSA and RainBank Rainwater Systems are committed to education and the advancement of rainwater collection. RainBank’s president Ken Blair is ARCSA’s North West Regional Representative.
