What is WaterSense?
WaterSense is a partnership program sponsored by EPA, helping consumers identify water-efficient products and programs.
What should be used to estimate the water storage capacity of a site during a site assessment?
Urban Hydrology for Small Watersheds Technical Release 55 (TR-55) or local equivalent for projects outside the U.S.
What are some ways to capture rainwater to prevent runoff?
LID and green infrastructure
What optional systems can be submetered for Water Metering?
Two or more of the following:
Irrigation
Indoor plumbing fixtures and fittings
Domestic hot water
Boilers
Reclaimed water
Other process water
What percent of water distribution must be submetered for irrigation, indoor plumbing fixtures, domestic hot water, or other process water?
80% must be submetered
What frequency must metered data be compiled for Building-Level-Water Metering?

What type of water is municipally supplied reclaimed/recycled water?
Non-potable water
What minimum percent reduction of outdoor water use is required from a calculated baseline?
30% reduction from the calculated baseline for the site’s peak watering month
How can reductions be achieved for WE Prerequisite Outdoor Water Use Reduction?
Plant species selection

55%
What must be conducted for Cooling Tower Water Use?
A one-time potable water analysis measuring at least the required five control parameters
What minimum number of cooling tower cycles would earn a project 2 points?
A 10-cycle minimum.
