Water is the most expensive utility in U.S. buildings.

Water costs have surged across every major U.S. market over the last five years — and the trend is going up.

51% of toilet water is lost to running toilets — not flushing.

Toilets account for roughly 25% of a building's total water use, meaning leaks alone can represent 12–20% of your entire water bill.
