Manufacturers are constantly researching new showerhead designs, products, and technologies.
Currently there are several research projects that are evaluating the effectiveness of low-flow showerheads as well as customer satisfaction with these products. Sponsored by the U.S. Environmental Protection Agency and two water providers (East Bay Municipal Water Utility District and City of Tampa Water Department), these studies measure water use in single-family homes before and after the installation of high-efficiency fixtures including showerheads, toilets and clothes washers. Results from these studies should be available in 2002.
