Placerville, Calif. — On Monday, May 23, 2011, the El Dorado Irrigation District (EID) Board of  Directors approved the award of a construction contract to Lodi-based TTS Construction for funding of a disinfectionprocess conversion project for the Reservoir 1 water treatment plant in Pollock Pines in the amount of $742,771.The Board also approved funding for associated special inspection services, system integration services, utility feesand construction contingencies, and staff time totaling $256,711, with total project funding authorized at $999,482.This upgrade will change how the Reservoir 1 water treatment plant disinfects its water by converting from the use of chlorine gas to the use of liquid sodium hypochlorite. “This upgrade will allow the District to continue to providehigh quality and  reliable water while reducing potential risks,” said Bob Rice, EID senior civil engineer. “It will alsobring the Reservoir 1 water treatment plant into compliance with Article 80 hazardous materials regulations of theuniform fire code, while significantly reducing the potential for public exposure and the District’s liability frompotential accidental releases of chlorine gas by converting to the use of liquid sodium hypochlorite.”

EID upgraded the El Dorado Hills water treatment plant’s chlorine treatment processes in the fall of 2010 and has pans to do the same at the Reservoir A water treatment plant near Sly Park in the future.

These disinfection process improvements will benefit all customers in EID’s service area by upgrading the facilities wth safer, simplified equipment, along with improving reliability of the disinfection process, said Rice. Construction o the Reservoir 1 upgrade is expected to be completed in January, 2012.

Capital Improvements Continue on Flumes, Canals, and Sewer Lift Stations

The District approved a capital improvement funding request of $111,000 for continued design work for improvements to be made to three sewer lift stations in El Dorado Hills: Business Park 1, Summit 1, and Timberline. Construction is expected to begin this fall. More information will be provided in public outreach meetings scheduled to begin this summer.

The Board also approved three separate maintenance projects on the El Dorado Canal (Canal). These projects include interim stabilization of the east rock wall abutment of Flume 30 at Bull Creek, installation of horizontal drains at two locations along the canal upstream of Flume 52A, and to rebuild Spillway 42. “The District’s vigilance in making these improvements is very important in ensuring that we maintain a safe and reliable water supply system that is protected as much as possible against catastrophic failures, such as what we’ve seen recently in other water conveyance systems in the region,” said Harry Norris, EID Board President.

First Quarter Financial Review Provided

Mark Price, EID finance director, provided the Board with a financial report for the first quarter, including January 1 through March 31 of 2011. According to Price the District has booked 15.5 percent of total projected 2011 revenues, as compared to 13.3 percent for the same period of 2010. This was primarily due to adopted rate increases and increases in hydropower revenue related to a new PG&E contract. Total operating expenses for the first quarter of 2011 were 18.8 percent of the operating budget, as compared to 17.9 percent for the same period in 2010. “Increased expenses for this quarter are due primarily to an accelerated payment of a one-time insurance premium and are expected to be more normalized for the rest of year,” said Price. “Staff has continued to keep departmental expenses down and we’re hoping that overall expenses for the year will continue to be favorable.”

In other business, the Board—

  • Awarded a contract to Sell Lumber in the amount of $129,031 for flume lumber and authorized funding of $659,900 for materials, staff time, environmental services, and related permits for the replacement of 320 feet of Flume 39/40. The work will be completed during the scheduled canal outage by District crews.
  •  Received reports from General Manager Jim Abercrombie on the status of the cost-of- services study committee and the domestic irrigation customer class. Abercrombie reported that the committee concluded their meetings on May 6 and discussed the next steps in the process, which includes presenting findings to the Board in a public workshop to be scheduled in the coming weeks. After the workshop, a series of public outreach meetings will be held to obtain public comment before bringing the issue back to the Board for further discussion in late summer. Abercrombie also presented information on the domestic irrigation customer class and a need to possibly integrate it into the small farm customer class, or other appropriate customer class. It was decided by the Board to hold off on any decisions about the domestic irrigation customer class until the overall discussion of the cost-of-services study Board workshop is held.
  • Heard a legislative update report from Bob Reeb, of Reeb Government Relations, EID’s state legislative advocate. Mr. Reeb reported on the success of the District’s legislative advocacy program to date and provided an update on the state budget negotiations. Reeb recommended that the District modify its prior positions on SB 474 and SB 900 in response to bill amendments. At the conclusion of Reeb’s report, the Board approved his position recommendations on this proposed state legislation.
