1.4 SYSTEM DESCRIPTION

1.4.1 Design Intent: Custom and "off-the-shelf" rainwater harvesting systems consisting of manufactured components integrated into an automated system. The system shall collect rainwater from a roof via drains, downspouts and conveyance piping; and convey rainwater through, self-cleaning, gravity fed pre-filters. Filtered rainwater is then stored in a storage tank. Water is drawn from the storage tank and pumped through a packaged pumping system to an irrigation or end use plumbing system. The pumping package is designed to provide water at the desired design point on an on-demand basis.

1.4.2 Design Requirements: Filter, store, and distribute harvested rainwater per ANSI 78.

1.4.3 Water Disinfection Methods: May include sediment filtration, ultraviolet treatment, chlorine injection, carbon filtration, or a combination thereof.

1.5 SUBMITTALS
