Rainwater Harvesting System and Component Specification Sections Per CSI:

CSI Section 33 10 05: Rainwater Harvesting Systems and Components

Rainwater harvesting is the practice of collecting and using rainwater, most commonly from roofs. Use of collected rainwater can provide building owners with high-quality soft water for irrigation and potable uses, reduce pressure on water-treatment plants, and reduce stormwater runoff and flooding. To use as potable water, filtration and purification are necessary. (See also 07 71 23 - Gutters and Downspouts & 22 32 00 - Domestic Water Filtration Equipment)

CSI Section 07 71 23: Gutters and Downspouts

Products that are effective at directing rainwater away from foundations increase building durability.

CSI Section 22 32 00: Domestic Water Filtration Equipment

Products included here are used to purify water. Such systems can help to ensure high-quality drinking water. Some are also key components of rainwater harvesting systems.

Rainwater Harvesting Products could also be specified under CSI Sections:

44 4300 - Water Filtering Equipment

33 1600 - Water Utility Storage Tanks

The Federal Green Construction Guide for specifiers on the WBDG (Whole Building Design Guide) website shows rainwater harvesting system and component specifications in Section 33 1620, Rainwater Harvesting.
