Commercial Car Washes: All new commercial car washes must be equipped with and operate recirculating systems. Existing car washes with recirculating systems must maintain and operate the recirculation system.
• Potable Irrigation of Nonfunctional Turf:
No person shall use potable water to irrigate nonfunctional turf on publicly owned landscapes after January 1, 2027. No person shall use potable water to irrigate Adopted 06/09/2025 Page 117 21665518.1 nonfunctional turf on commercial, industrial and institutional owned landscapes after January 1, 2028. No person shall use potable water to irrigate nonfunctional turf on homeowners’ associations common area landscapes after January 1, 2029. No person shall use potable water to irrigate nonfunctional turf on publicly owned landscapes located within disadvantaged communities (DAC) after January 1, 2031 or upon the date state funding for turf conversion to climate appropriate landscapes within DACs becomes available. However, the use of potable water is not prohibited to the extent necessary to ensure the health of trees and perennial non-turf plants or as necessary to address an immediate health and safety need.
F. Metering
IRWD’s system is considered fully metered. In 2017, IRWD developed a new water loss control program to address the following areas:
1) Identification of malfunctioning meters (under-registering and stopped);
2) Accounts using substantially less than their water budget;
3) Authorized unmetered connections; and
4) Unauthorized connections to IRWD’s system.
IRWD developed a tool that utilizes a custom algorithm to identify malfunctioning meters and accounts with usage far below their budget. The program also identifies authorized unmetered connections that can be metered to improve data accuracy. IRWD has incorporated use of drone technology to find and document unauthorized unmetered connections. The metering program also quantifies historical usage for unauthorized connections so that IRWD can bill to recover lost revenue. In 2024, IRWD completed an Automatic Metering Infrastructure (AMI) and Static Meter Feasibility Study (AMI Feasibility Study) to evaluate alternatives to the District’s manual meter reading process. The evaluation identified that static meters, using ultrasonic or electromagnetic technologies, can provide more accurate measurement of low flow water use, which can significantly reduce lost revenues and identify leaks more quickly. Following the AMI Feasibility Study the District developed an AMI Implementation Plan. IRWD is preparing to install AMI throughout its service area and use static meters. This will further enhance the District’s metering, water loss identification and control programs.
