KOHLER, Wis. -- As various parts of the country deal with droughts or chronic water shortages, one Wisconsin company is among those providing water-saving solutions.

Kohler Co., located near Sheboygan, hopes its toilets can help revolutionize the nation.

Older toilets use between three and five gallons of water per flush. The previous generation of low-flow toilets uses about 1.5 gallons, but customers have criticized their performance, WISC-TV reported.

The newest generation uses 20 percent less than that, and the Environmental Protection Agency said these high-efficiency toilets work much better.

Last month, California mandated that toilet retailers offer increasing numbers of high-efficiency toilets for sale, and other states are following suit.

A Kohler spokesman said sales used to be concentrated in traditionally dry areas of the country, but now there's demand all over the nation.
