Water plant cost overrun may hit $200,000

Misreading notes has caused an estimated cost overrun of up to $200,000 on the $7 million Lake of the Pines Water Treatment Plant expansion.

Owen Engineering firm owner Webster Owen told a Nevada Irrigation District engineering committee Wednesday his firm, “made a mistake” when two walls at the plant were built 4-feet lower than levels the plans called for.

Had that mistake not been caught in a recent consultation with the contractor, the plant would not have worked upon completion, Owen said. “It means the water wouldn’t go through the plant,” if the mistake hadn’t been caught. NID Senior Engineer Vern Smith said the plant has a November completion date.



In a letter to NID from his Cameron Park office, Owen admitted “our design team misread the survey notes.” He recommended the walls be extended 4-feet to meet specifications, allow water flows to reach filters and to allow for future expansion use.

“This won’t be accepted well but it looks like it has to be done,” said committee member R. Paul Williams. He and fellow committee member George Leipzig agreed with NID Chief Engineer Tim McCall to bring the matter before the entire NID board next Wednesday.




Owen said Pacific Mechanical Corp. feels it can extend one of the walls in March and one in April to meet a deadline for water to be filtering through the plant in May or early June. Owen said weather and timely shipments of rebar for the concrete could alter the schedule.

“We need the construction done in a timely manner. We need authorization to go ahead,” McCall said.

“We met with the contractor last week and gave him the drawings to get a cost,” Owen said. “We’ll have a price in a few days…The contractor is fair but they won’t do it for no profit.”

After the meeting, McCall said the cost overrun was estimated at $100,000 to $150,000 by Owen. However, McCall said he was estimating the overrun at “$200,000, just to be safe.”
