Paonia domestic water users can look forward to a new filtration system for the two-million-gallon Lamborn Mesa water treatment plant. The original estimated completion date of Dec. 31 of this year will now more likely be in April or May of 2015.
Until the new plant is commissioned, the Town of Paonia will have to notify its domestic water users every three months that their water is not in compliance with the latest water standards of the Colorado Department of Public Health and Environment.
The new filtration system is designed to exceed those standards once it is up and running. The water is safe to drink, it just doesn’t meet the latest requirements.
Kellie Knowles, WestWater Engineering project engineer, presented three proposals to the Paonia Town Council on May 13. In her memorandum she stated, “Proposals represent only the membrane filtration equipment, controls and accessory items along with startup assistance and operator training. Proposed costs do not include other components of the overall project such as the required building expansion and equipment installation, electrical service upgrade, Reynolds Spring raw waterline extension, or the new two-million-gallon finished water storage tank.”
The council accepted the proposal by Filter Tech Systems of $676,240. It was the lowest bid. Evoqua Water Technologies bid $709,950 and Pall Water Processing bid $761,352.
Knowles wrote, “Based strictly on costs, Filter Tech Systems’ adjusted proposal amount combined with annual operating costs plus replacement costs in future years is the lowest.”
The Filter Tech Systems’ membrane filtration will require less maintenance than a Pall system. It was reported at the meeting that if a module goes out with the Evoqua system, a number of modules could have to be removed for repair of the one module.
The Pall proposal was for a micro-filtration system; Filter Tech and Evoqua are ultra-filtration.
Travis Loberg, public works director, said that while it would be nice to only have to stock parts from Pall since the other water plant uses their micro-filtration, he liked the Filter Tech ultra-filtration system more.
With Filter Tech, the fabrication of the ultra-filtration system can be postponed until the site is ready for it. The town would have to pay storage costs of $2,300 a month for the Pall system.
The council accepted the proposal by Filter Tech Systems on May 13, and accepted the contract after it was reviewed on May 20.
Knowles also said that bids are due on June 16 for lining and piping upgrades and waterproofing the roof for the half-million-gallon water treatment plant.
