CSA Group, ICC to Develop Rainwater Collection System Standard

Feb. 26, 2014
U.S./Canadian consensus Committee appointed; will hold first meeting in April

With the appointment of a U.S./Canadian Consensus Committee, the Intl. Code Council (ICC) and CSA Group are starting a project to develop the new CSA/ICC 805 Rainwater Collection System Design and Installation standard. The 18-member ICC/CSA Rainwater Collection Design and Installation Consensus Committee, made up of nine U.S. representatives and nine Canadian representatives, will create the standard that will ensure the basic safety and performance of rainwater collection systems. The standard will be developed in accordance with both ANSI and Standards Council of Canada accreditation requirements for use throughout North America.

ICC’s International Green Construction Code (IgCC) addresses rainwater harvesting and is used as the basis for an appendix in other codes. The groundbreaking revision to ICC’s 2015 International Plumbing Code contains comprehensive, non-potable water provisions in a new chapter covering rainwater, gray water and reclaimed water.

CSA Group has embarked on a number of related standards projects, including CSA B126 Water Cisterns. This joins the CSA B128.3 Performance of Non-Potable Water Treatment Systems standard, which specifies water systems requirements for treating gray water or wastewater for reuse in other applications.

Development of the standard began two years ago with a Project Initiation Notification System (PINS) with the American National Standards Institute filed by the Code Council. ICC and CSA announced their intent to develop a joint U.S./Canadian standard last April.

The ICC/CSA Rainwater Collection System Design and Installation Consensus Committee will hold its first meeting April 9 to 10, at the Hyatt Regency O’Hare in Rosemont, Ill. The purpose of the meeting will be to elect committee leadership, establish task groups and begin work on the standard.
