EPA Releases New Water Data

1 MIN READ
By
The EPA just released a new national residential water-use study that compares indoor and outdoor water consumption data from three categories: existing homes originally studied in 1999, “standard” homes built after 2001, and new “high-efficiency” homes built to equal or exceed WaterSense performance criteria. The first new study in a long time, it reveals significant improvements under way while identifying critical areas that need to be addressed as new priorities. Researchers from Boulder, Colo., water engineering firm Aquacraft worked with water utilities in nine cities to collect data from each group in each city, including real-time monitored water consumption from the new homes.
