FOR IMMEDIATE RELEASE

Placerville, Calif. — At its July 25 meeting, the EID Board of Directors received and filed an update of the Draft 2011 Water Resources and Service Reliability Report. First presented at the June 27, 2011 meeting, the Board asked that the data be recalculated using a more conservative approach to reflect the unit demand reduction observed in recent years.

The draft report is presented to the Board in order to obtain their input as well as any public comment prior to the release of the final version. The report is updated annually to determine water supply, potential demand, and meter availability within the District. According to Brian Mueller, EID’s director of engineering, water consumption per unit in the last ten years has been steadily increasing, resulting in a very conservative unit demand projection. However, in recent years the District has seen a sharp decline in water demand, most likely due to a combination of wetter, cooler weather, increasing conservation, and the economy. “The average usage for a single family residential home in El Dorado Hills has declined from 0.83 acre-feet (AF) in 2008 to 0.61 AF in 2010,” said Mueller.

Staff evaluated three different options to re-calculate unit demands to include recent declines and decided upon an option that results in a new unit demand projection that best reflects potential demands that may be experienced today and into the next few years. The selected option’s calculation excludes the maximum and minimum values using the last 10 years of data and averages the remaining values. This calculation reduces unit demand values by approximately 10 percent from the previous calculation and results in a moderately increased equivalent dwelling unit (EDU) availability. “Using this method, total potential demand for the District is calculated at 45,800 AF. The single-family residential unit demand in El Dorado Hills is reduced from 0.86 AF/EDU to 0.77 AF/EDU, and for the western/eastern area it is reduced from 0.59 AF/EDU to 0.54 AF/EDU,” said Mueller.

According to Mueller, the new calculated potential demand was compared against actual historical diversions in the system and the revised method has compared very well to actual recent demands experienced in a dry year and gives confidence that the unit demands are appropriate and reasonable.

In other business, the Board—

  • Received a redistricting process update from General Counsel Tom Cumpston. Cumpston reported that the District is nearing completion of the redistricting process. Public outreach meetings have been conducted in El Dorado Hills, Cameron Park, Placerville, and Camino to obtain public input and there is one additional Redistricting Advisory Committee meeting left before the committee forwards several redistricting options to the Board for action. Despite extensive publicity, the public outreach meetings have been sparsely attended by the public. The Redistricting Advisory Committee plans on providing three to four alternatives of boundary options for the Board to consider at its August 22 meeting. All materials related to the District’s redistricting effort may be viewed on the Redistricting page of the District’s website.
  • Heard an update regarding the District’s Emergency Operations Plan (EOP). The EOP has been updated and revised to ensure compliance with local, State, and Federal regulatory requirements. The El Dorado County Sheriff’s Office of Emergency Services has provided financial assistance through an emergency preparedness grant reimbursement in the amount of $5, 500 for the plan update and associated training of staff. The EOP is intended to supplement existing emergency action plans and procedures, and reflects the District’s emergency response system for mobilizing District personnel and other resources during emergencies. The plan also identifies outside support and resources available through Mutual Aids and/or Mutual Assistance.
  • Awarded a professional services contract to MCC Control Systems in the not-to-exceed amount of $73,050 to repair or replace all electrical equipment and a cabinet damaged during an arc flash event at the Deer Creek Wastewater Treatment Plant.
