Monday the El Dorado Irrigation District Board of Directors approved a cost-sharing agreement with the El Dorado County Water Agency for nearly $504,500 worth of projects, all of which are already in various stages of progress.
In May the board contracted with Innovyze for $103,750 to develop a hydraulic water model and Graphic Information System model for its water and recycled water systems. The Water Agency is offsetting $75,000 of this cost, according to Cindy Megerdigian, EID water and hydro engineering manager.
One of the more expensive projects partly under way is the Main Ditch improvement with the Water Agency reimbursing the district for $195,000. At this point the district has used grant funds from the Water Agency to complete “wetland delineation, red-legged frog habitat assessment, cultural resource surveys and evaluation, and inventory of domestic wells and septic systems.”
The Main Ditch is three miles long and delivers water from Forebay to Reservoir 1 Water Treatment Plant. The $380,000 project will pipe that ditch and save 1,300 acre-feet of water annually plus deliver cleaner water to the treatment plant.
A third project under way is a $400,000 contract with NLine Energy of El Dorado Hills to design a 370 kilowatt hydroelectric station upstream of Tank 7 on the Pleasant Oak Main to work in parallel with a pressure reducing station and offset district electricity expenses.
The Water Agency is funding $224,000 of this project.
Most of EID’s half of the expenses are being covered by capitalized labor related to staff engineering work.
