Integrated Water Planning through Building Level Cascade of Water Use
EW-201155
Objective
The objective of this project is to demonstrate and validate the retrofit of existing building potable water systems with water conservation and reuse technologies that reduce overall demand and reserve potable water only for the purposes for which it is required. Although water conservation technologies are not unique, the concept of combining conservation and reuse on the building level will demonstrate the optimal use of water within a building at the amount and quality required. This technology demonstration will take place at Fort Irwin, California.
Technology Description
This project will demonstrate an integrated suite of commercially available building water conservation technologies coupled with graywater reuse systems. Specific technologies that will be tested include (1) water efficiency upgrades to faucets, showerheads, urinals, and toilets; (2) centralized graywater treatment and reuse systems placed optimally at installation buildings that require minimal retrofit, such as recreation centers; (3) distributed graywater treatment and reuse systems placed optimally in buildings that cannot justify a central retrofit; (4) rainwater collection with the option of groundwater recharge; and (5) water harvesting systems that collect rainwater, condensate from cooling processes, and humidity extracted with dessicants.
Benefits
DoD currently lacks detailed cost and performance data and specific implementation guidance to fully implement a building-level water reuse system. Retrofitting existing buildings with an integrated water use cascade will help maintain critical operation centers in regions that are currently facing water shortages, promote goodwill in surrounding communities, and serve as a model of sustainable development for other governmental and nongovernmental organizations. A significant benefit is establishing good practice for best use of a critical resource in a future of increasing scarcity and water pricing. (Anticipated Project Completion - 2014)
