Public Utility District
WORKSHOP
To: Board of Directors
From: Ed Taylor
Date: April 15, 2009
Subject: Discussion of a Backflow Program
1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop item is an update of the Cross-Connection Program.
2. HISTORY
On January 7, 2009, a workshop item was presented to the Board on the District's
Cross-Connection Program. There is a standard notification and compliance program
for all backflow devices in the District. The Cross-Connection program consists of
tracking 650 devices. Staff sends out annual testing notices for each device, follows
up, and files a report with the Department of Public Health Services.
Staff reviews new and remodeled commercial construction for cross-connection
requirements, and performs inspections on high hazard businesses that might require
backflow protection. The current program utilies 50% of a full time employees' time,
including supervisory time.
3. NEW INFORMATION
Staff Recommends that the Cross-Connection Program be expanded to provide
additional protection to the customers. This expanded program is proposed to include:
• An annual inspection of high hazard commercial customers
• A two-year inspection of low and medium commercial customers
• A program of verification testing of devices to validate that the devices are being
properly tested
• A program to coordinate with the Town of Truckee to identify residential customers
that have potential high hazards
This expanded level of effort may involve an estimated additional 50% of a full time
employee. The additional program benefits equal a higher level of protection for the
customers.
The schedule for the additional elements that are proposed are:
- Start annual inspections of high hazard customers - December 2009
- Start two-year inspections of all other commercial accounts - March 2010
- Start verification program - August 2010
- Start coordination program with the Town - March 2010
4. FISCAL IMPACT
The additional program cost are estimated to be approximately $100,000/ year
Revenue sources include:
- Shifting of existing resources'
- Cost savings from other programs
- Fees
