**THIS IS A PDF VERSION- A Printed manual can be produced upon special request
Jointly developed by ASPE and the American Rainwater Catchment Systems Association (ARCSA),
ARCSA/ASPE/ANSI 78-2015 provides guidance on how to install and maintain a safe alternative to utility-
provided water and to optimize stormwater utilization to reduce dependence on municipal potable water
systems. Use of the standard will ensure that consumers are not at risk from poor design, installation,
maintenance, or illegal work and that the stormwater catchment system will assist in maintaining and enhancing the quality of the environment while assisting compliance with the intent of relevant regulations and government officials.
