Los Angeles water wasters could be fined up to $40,000 per month under new regulations created in response to a crushing drought that’s poised to stretch into a fifth year.

Mayor Eric Garcetti signed the new regulations into law Wednesday. They allow the Los Angeles Department of Water and Power (LADWP) to fine homeowners between $1,000 and $40,000 for what Garcetti described in a statement as “unreasonable use.”
