Lyon County utilities update: multi‑million dollar projects continue; Highway 50 sewer project rebid after single high bid

Lyon County utilities staff gave the board a first‑quarter progress update on six capital projects and the board rejected a single high bid for a sewer replacement on Highway 50 in Dayton, directing staff to rebid after revising specifications.

Utilities engineer Sho Panda presented the update. He told commissioners the Highway 50/Dayton Valley Road gravity sewer replacement project received only one bid that exceeded the engineer’s estimate by about $1.2 million; staff and the project engineer recommended rejecting the bid under NRS 338.1385(d) because the single, noncompetitive bid did not serve the public interest. The board voted to reject the bid 5–0.

The utilities update described a $20 million wastewater plant expansion contract that had spent roughly $14.5 million to date, with a current delay in major equipment deliveries. The project, originally scheduled for completion in September 2025, is now expected to finish in May 2026, staff said. The update also covered Silver Springs General Improvement District (GID) projects: an effluent disposal study, a recommended filter system rehab estimated at about $972,000 (staff are seeking grant funding to cover up to 80% of that work), and a dewatering alternative to address filling sludge ponds.

Why it matters: The sewer replacement and plant expansion are core infrastructure projects with capital and schedule risk. Rejection of the Highway 50 bid will likely delay construction until the fall rebid window when contractors’ schedules may be more open and competitive.

On the Highway 50 item, the board accepted staff’s recommendation to reject the bid and rebid after reviewing bidding documents. Utilities staff told commissioners they had engaged plan holders and that scheduling constraints and supply‑chain uncertainty contributed to limited bidder interest; staff will review specs and seek better market timing.

On the plant expansion, Sho Panda said change orders processed to date total about $427,000 and the county may present additional change‑order requests and a time‑extension request in late summer if needed. The utilities department said it will try to manage costs within the project contingency and continue working with the contractor and equipment suppliers to complete the plant expansion.

The board’s rejection of the Highway 50 bid was a formal action under NRS; staff will return to the board with revised bid documents and a planned fall rebid schedule.
