Project: 824281 Leak Detection Program
Origination Year: 2003-04
Planned Completion Year: Ongoing
Department: Public Works
Project Description / Scope / Purpose
Project Information Sheet
Type: Water
Category: Special
Project Manager: Jim Craig
Fund: 460 Water Supply and Distribution Fund
Sub-Fund: 200 Water Capital Subfund
Project Coordinator: Val Conzet
The project provides funding for a leak detection assessment of the City's 320 miles of water lines. Approximately 100 miles of City pipes will be assessed every year for the first three years at an
estimated cost of $30,000 per year. After the initial assessment, one third of the City will be assessed every three years at an estimated cost of $30,000. This program is necessary because of the
aging infrastructure of the water system.
As recommended by the California Urban Water Conservation Council and as identified in the City's adopted 2005 Urban Water Management Plan as Demand Management Measure #3, leak
detection and system water audits are to be performed periodically by an outside contractor. Any water loss due to leakage, theft, under-billing of customers, faulty control systems, or any other
reason represents revenue losses to the City. Follow-up actions when leaks are located may include repairing leaky pipes and valves, replacement of water mains with a history of serious leaks,
annual exercising of valves, and a corrosion control procedure (i.e. cathodic protection program). The primary benefit of early leak detection is finding a leak before it becomes a larger problem,
resulting in more water lost. Leak repair also keeps leaks from deteriorating into large-scale problems that can lead to system failure, causing emergency conditions and compromising public safety.
This program has been very successful at identifying leaks within the City's 320 miles of water lines. Approximately 345 miles have been inspected and a total of 66 leaks, representing a loss of over
$4,300 per day, have been identified and repaired.
Project Evaluation and Analysis
This project represents the most cost-efficient way to avoid water loss and future infrastructure problems in the water system. In FY 2011/12, following the completion of the current assessment
cycle, the frequency of the audit schedule will be revisited.
Fiscal Impact
This project is funded by the Water Supply and Distribution Fund.
