The City of Mexicali plans to fine residents who are found watering curbs and washing vehicles in the public way.
Fines can go up to around $650.
A city official said the disciplinary action seeks to stop misuse of water.
City Director of Environment Manuel Zamora said fines can be even higher in case of recidivism.
The director said Mayor Norma Bustamante instructed city officials to enforce the ordinance to stop the issue from increasing.
Also, the city plans to fine businesses found in incompliance or in violation. The agency plans as well to start an education effort to make people aware about proper use, conservation and consumption reduction of water.
