Reason for Recommended Action/Background
In February 2018, following evaluations of the Wild Wings Wastewater Recycling Facility, it became imperative to make immediate and necessary repairs to continue to operate the facility safely and in compliance with the County's wastewater discharge permit. As the original installers of the facility, the County contracted with EEI WSD Joint Venture for these services, understanding additional issues might be identified in the process.

With much of the rehabilitation complete in Spring of 2018, new issues were identified with the Wastewater Recycling Facility and with related operations (entire sewer system and water system). The contract was amended on May 8, 2018 to authorize additional services, including response to multiple failures at Lift Station B (part of greater sewer system) and the need to replace existing obsolete radios on the water system. All other additional services were related to rehabilitation of the Wastewater Recycling Facility.

This second amendment to the agreement again identifies new issues related to rehabilitation of the Wastewater Recycling Facility. Of note is the purchase of a new dewatering system (Volute press $205,400). A dewatering system significantly diminishes hauling costs by squeezing wastewater out of the sludge for treatment and discharge onto the golf course. Estimated cost savings in hauling related to regular and on-going operations is $5,333 per month. The estimated savings in hauling related to the one-time required clean-up of the recycled water pond, as required by the January 23, 2018 Central Valley Regional Water Quality Control Board Notice of Violation, is $144,000. As the window of opportunity is closing to complete clean-up of the recycled water pond prior to winter rains which will increase the pond's contents, it is critical a new dewatering system be put in place as soon as possible. Note: the specifications for a dewatering system could not be determined until now, when the Wastewater Recycling Facility was stablized. Four different systems were evaluated and the Volute press determined to be the most cost-effective given the quality of the system (less equipment with moving parts to maintain), reduction in chemicals necessary to operate the system in comparison to the irrepairable system currently installed ($20,600 annually) and reduced energy consumption.

Other additional services include blower system modifications, micro processor replacement, water system control trouble-shooting, operational support, a radar level transmitter and replacement of turbidity meters supply pipe.
