Placerville, Calif. — At its January 10, 2011 meeting, the El Dorado Irrigation District (EID) Board ofPicture of dewatered deteriorated canal downstream of Flume 41 Directors approved funding of $248,852 for the design and permitting for the Flume 41 replacement project. Included in that amount was a $138,852 contract change order to Carlton Engineering for design services as well as $110,000 for staff support, acquisition of agency approvals, and permits. The Flume 41 project is part of the District’s long-term rehabilitation program for the 22.3-mile El Dorado Canal, which delivers drinking water from four high-Sierra reservoirs to customers throughout the District’s service area and supplies water to generate EID’s state-certified renewable hydroelectric power.

The additional work includes design of access road improvements that will facilitate equipment and vehicle access to Flume 41 during construction, and also includes design of a concrete canal section in need of replacement. Due to the difficult access constraints and site conditions, permanent road improvements have been identified that can be made to facilitate these projects as well as future construction and maintenance work in this geographically remote area. “These road improvements will be made in lieu of the costly practice of hiring helicopters to transport tools, materials, and equipment, saving the District nearly $1.5 million in throw-away costs,” said Daryl Noel, EID Associate Engineer. This contract scope modification will allow the District to better utilize the funds on needed infrastructure improvements and permanent heavy equipment access that will continue to provide immediate and long-term benefits for the future replacement and maintenance of this important conveyance facility, which delivers drinking water to approximately one-third of the District’s customers.

The access road, along with the flume and canal section to be replaced, is located on U.S. Forest Service (USFS) property and the District is consulting with USFS staff on the proposed improvements. “This project represents good cooperation between EID and the USFS, allowing both of us to be winners in the end,” said Jim Abercrombie, EID’s General Manager. Once design work and environmental approvals are complete, the access road improvements are scheduled for late 2011 or early 2012, prior the flume and canal replacement work which will commence in the fall of 2012.

In other business, the Board—

  • Received a project update on the status of the El Dorado Hills Water Treatment Plant reliability and expansion project. The plant has undergone major improvements between 2008 and 2010 to improve water quality, treatment, safety, service reliability, and capacity expansion for customers.
  • Approved a 90-day extension of the Weber Advanced Funding Agreement to allow discussion of possible alternatives to expiration of the agreement to continue; and to authorize the General Manager to sign it on the District’s behalf.
  • Received a report from General Manager Jim Abercrombie on the results of the 2010 Customer Survey. In November, 2010, a survey was sent to 4,000 randomly selected customers. The return rate was 24%— 7% higher than 2009. Consistent with the 2009 survey, our customers rated our service levels very high, and water quality and cost ranked as customer’s highest priorities, followed by water reliability and water security. The summary of results has been posted to the District’s document library at
