International Water Conservation Code Provisions IWCCP

The IWCCP meets the industry’s need for a resource that contains the water conservation-related provisions from the 2021 International Codes and selected standards in one document. The IWCCP is organized such that it provides the best and most comprehensive tool for the design, installation and administration of potable and nonpotable water conservation and efficiency systems. Although a few chapters apply to both commercial and residential, it is similar to the organization of the International Solar Energy Provisions® (ISEP®), the commercial and residential provisions have been presented in separate chapters, to make it user friendly and easy to apply.

Two important resource standards are included in full and excerpts of the water conservation provisions of another are included:

• Excerpts from the ICC 700-2020 National Green Building Standard®
• ASABE/ICC 802-2020 Landscape Irrigation Sprinkler and Emitter Standard
• ANSI/RESNET/ICC 850-2020 Standard for the Calculation and Labeling of the Water Use Performance of One- and Two-Family Dwellings Using the Water Rating Index
