Cost to repair the damaged lining of the one million-gallon storage tank at the Clock water treatment plant will exceed $78,000.
At the June 12 board meeting trustees approved a bid to sandblast the storage tank, which mainly provides potable water to Paonia proper. The floor of the tank was heavily damaged in 2015 and repairs were completed in 2016. A fall 2017 survey by the Colorado Department of Health revealed that the lining had failed, putting the tank at risk for contamination. The health department ordered the tank shut down until the lining is repaired.
Eckert-based Grand Mesa Mobile Dustless Blasting was awarded a bid of $78,364 to sand blast the tank in preparation for a new lining, with a completion time of 16 days. Grand Mesa submitted a second bid of $68,568 to complete the project in 25 days.
Denver-based Lightning Mobile submitted a bid of $150,000, with a 30-day completion, and Western Colorado Mobile Dustless Blasting in Fruita submitted a bid of $300,259. The main difference in the bids is the materials used in the blasting process, said Loberg. The Fruita company uses a more expensive glass medium, while Grand Mesa uses a more coarse material.
Loberg recommended Grand Mesa's 16-day bid, adding that they were the only company to test their material on the tank. "I think they will do a good job," said Loberg.
Trustee Bill Bear, who serves on the Public Works Committee, agreed with Loberg's recommendation. "In light of where we're at with the drought conditions, I think it's prudent that we do this quicker" and get the tank back in service.
The lining itself will add to the cost of the project. Requests for bids for a new lining will go out once the sandblasting project is complete.
Trustees also awarded a bid to install handicap ramps to existing sidewalks throughout town and repair broken sidewalks. C&N Construction, Inc., of Delta, submitted a bid of $7.99 per square foot to replace sidewalks, $1,900 for each handicap ramp, and $25 per linear foot for curb and gutter replacement, for a total cost of $47,500.
C&N, which has done other sidewalk projects for the town, submitted the only proposal. Knight said four packets were sent out, and the other three companies were too busy this summer to submit bids.
The project will exhaust the town's sidewalk repair fund, which comes from a voter-approved, $3 fee charged monthly on in-town water, sewer and trash bills. Funds are limited to repair and replacement of existing sidewalks. Knight said the town is also exploring the possibility of using funds from other sources to build new sidewalks this summer.
The town is considering a widening project on the Samuel Wade Bridge.
Also known as the Third Street Bridge, the project is in the discussion phase. Town Administrator Ken Knight said the town is pursuing funding for the re-decking project from the Colorado Department of Local Affairs. The funds are available, "especially if design is both handicap accessible and improves safety," said Knight. Both safety and handicap accessibility are concerns and "key components" in meeting standards for lane and sidewalk widths with the existing deck, explained Knight.
Public Works Director Travis Loberg is working with the Colorado Department of Transportation to determine whether the bridge abutments are capable of supporting such a project. A CDOT engineer is expected to inspect the bridge in the near future, said Loberg. If the current support system is inadequate, the supports would have to be widened, increasing the cost of the project.
The town recently completed a stabilization project on the bridge. "Because of all the work we just did in the river, we know those supports are solid," said Knight. "But the question is, can we put a wider deck on there without having to dramatically change that support structure?"
