Council approves RO system repairs
Eric McPeak, local manager for Alliance Water Resources, told the Nevada City Council during a meeting Wednesday, which was rescheduled from Tuesday, that they were replacing more of the membrane elements in the reverse osmosis system this summer than usual,
“We’re doing more this year than in the past. We’ve been having more fouling of the elements,” McPeak said.
“The water treatment plant currently has 216 reverse osmosis membrane elements that are contained in 36 pressure vessels. Operators perform cross section efficiency testing on pressure vessels at scheduled intervals. The results are showing reduced efficiency in several pressure vessels, indicating that these elements are at the end of useful life and need to be replaced. Replacing these elements will extend efficient operation life of the overall system and add additional capacity to meet daily water demand,” Nevada City Manager JD Kehrman told the council before it voted 5-0, to accept the low bid of $45,900 from Consolidated Water Solutions for 108 membrane elements.
McPeak said the current water usage is about 800,000 gallons per day, but during the summer it climbs to 1.1 to 1.2 million gallons per day.
The water treatment plant is designed to produce 1.4 million gallons of water per day.
“The more [elements] we change out the longer life we get,” McPeak said.
In other business the council:
• Voted 5-0, to approve the appointment of Jerry Haggard to the planning commission to replace Dick Shorten. Haggard’s term will expire in March 2021.

Peters Municipal Golf Course are in a low-lying environment where the air is stale and the moisture is high, creating problems with grass on the greens. Mayor Brian Leonard said last year they had to replace all the grass on Number 3 and 5 greens, where the grass completely died out. Novak said she had trouble voting for this purchase with the course continuing to lose significant amounts of money.

The city will receive an annual participation payment of $27,072.50, plus curtailment payments for each event. There will be no reduction in facility operations or services to resident,
