Important Drought Notice: The local conservation standard has been adjusted for Golden State Water’s So. San Gabriel (Monterey Park, Rosemead, San Gabriel) and So. Arcadia (El Monte, Irwindale, Monrovia, Temple City ) water systems. Customers may now water outdoor landscapes up to three days per week with new voluntary conservation targets.

System Watering Days (Even) Watering Days (Odd) Reduction Goal November Reduction Total Reduction
So. San Gabriel Mon, Thu, Sat Tue, Fri, Sun 10% 11% 13%
So. Arcadia Mon, Thu, Sat Tue, Fri, Sun 22% 20% 23%

* Reductions compared to 2013 usage
Total Reductions: June 1, 2016 – Jan. 8, 2017
Chart Key: Meeting Goal / Not Meeting Goal

This conservation standard is aligned with the State Water Board’s shift to locally-developed conservation strategies, which challenges water providers to implement conservation policies and supply investments to address the ongoing drought emergency. These standards could be revised pending the state’s verification of self-certification data and developments related to local water supply conditions and conservation.

Staged Mandatory Water Conservation and Rationing

Stage 1 (current stage): Customers may water outdoor landscapes up to three days per week. All watering should occur before 8 am or after 7 pm,  and should not exceed 10 minutes per station.

Stage 2: Irrigation restrictions from Stage 1; $2.50 emergency surcharge per CcF over allocation
Stage 3: Irrigation restrictions from Stage 1; $5 emergency surcharge per CcF over allocation

Average Monthly Residential Water Usage in San Gabriel

  • Average water bill is currently $48.16, excluding any applicable credits or surcharges.

Urban Water Management Plan (UWMP)

UWMPs are prepared to ensure adequate water supplies are available to meet existing and future water demands. Every five years, Golden State Water and all water systems that supply more than 3,000 acre-feet of water per year or serve more than 3,000 connections are required to update their UWMPs. See Golden State Water’s 2010 South Arcadia UWMP and 2010 South San Gabriel UWMP.


  • Golden State Water plans to invest more than $11.1 million dollars in local infrastructure improvements in 2016.
  • The 2016 investments include water supply enhancements, distribution and ongoing improvements designed to replace old meters, mains and safety equipment.
