• We have updated the cost benefit analysis and worked with Lynn to update the water loss numbers. We will see the results in a couple of months. Field Communications
• The Field Communications upgrade, first phase, will include a new tower at the Plant that is taller than what we have.
• The tower will be used as a communications hub to access SCADA more accurately than is possible now. The tower will be located behind the Lab building. 4. OTHER El Dorado County Water Agency (EDCWA)
• Julie is working on the project list for 2020 that is due by the end of March. The list will be similar to the prior list since a number of our projects from last year were not funded. a. El Dorado County Water Agency

• The City bid this project without including the District’s bid item descriptions to the contractor.
• Once the bid items descriptions were provided to the contractor for pricing the bid amount went above our current budget.
