Water Conservation Ordinance

Current Stage: 2
The City of Corona Department of Water and Power is currently in stage 2 of the Water Conservation Ordinance.

History of the Ordinance
The Corona City Council adopted Ordinance No. 2962 on January 7, 2009, in response to drought conditions in the State of California. This water conservation ordinance sets forth guidelines for conservation through five different stages of reductions. It details activities which may be prohibited during times of water shortage emergencies, as well as consequences that the City may take in order to ensure compliance with these guidelines, including fines and penalties. The Corona City Council amended the Water Conservation Ordinance on July 1, 2009 by adopting Ordinance No. 2996.

Prohibited Activities
Three activities are identified in the ordinance as unreasonable uses of water, and are prohibited at all times, throughout all Water Conservation Stages:

  • Allowing water to leave a person's property by drainage onto adjacent properties or public or private roadways or streets due to excessive irrigation and/or uncorrected leaks
  • Failing to repair a water leak
  • Using water to wash down sidewalks, driveways, parking areas, tennis courts, patios or other paved areas, except to alleviate immediate safety or sanitation hazards

Conservation Stages and Restrictions
The five water conservation stages are:

Stage Water Supply Status Water Conservation Requirements
Stage 1 Normal Water Supply Recommended conservation practices
Stage 2 Minimum Water Shortage Reduce usage by 10% to 15%
Stage 3 Moderate Water Shortage Reduce usage by 16% to 30%
Stage 4 Severe Water Shortage Reduce usage by 31% to 40%
Stage 5 Critical Water Shortage Reduce usage by more than 40%
