Special to The Gardner News
Gardner’s Utility Advisory Commission (UAC) met on April 6 and discussed replacing equipment at Hillsdale Water Treatment Plant and an electrical facility transfer agreement with KCPL. Members.
KCPL facility transfer
The commission considered recommending the city council approve a KCPL Facility Transfer Letter of Agreement.
John Krievens, staff engineer, presented the details to the commission.
The city will pay KCPL $20,000 to complete the transfer, which includes significant work KCPL will provide.
The agreement releases city owned equipment that is located in the KCPL Moonlight Substation.
“We have equipment that’s located in the KCP&L site, and we want to release this equipment, so now it’s no longer our responsibility. The title and responsibility transfers to KCPL,” said Krievins.
It also provides for the assistance of KCPL to remove the out of service transmission line to Substation #1, install new protective relay panels and place the equipment into service.
All engineering, construction and maintenance crew costs for this project are to be considered paid by Gardner.
The commission voted to recommend approval to city council.
New equipment for Hillsdale
The commission considered recommending council approve a supply contract to replace Hillsdale intake screens.
Gonz Garcia, utilities director, gave the staff summary.
In June 2016, zebra mussels were found in Hillsdale Lake. The population appears to be low density at present, however there is no known method to completely rid a lake of zebra mussels.
Garcia explained why this nuisance species can be a big problem for water intake facilities. The mussels attach to water intake screens and can change flow velocity, increase pumping costs and eventually can block screens altogether.
The Kansas Department of Health and Environment (KDHE) recommends copper screening to prevent fouling or plugging by zebra mussels.
The staff collected three bids and recommended the lowest, for $43,300 plus tax, freight and insurance.
“Elgin Separator Solutions will apply a coating of copper alloy, and they guarantee it for 25 years,” he said.
The purchase is for the screens only, not installation.
“Once we get the new screens, we have some contract divers who will go down, get the existing screen out and put the new one in.”
Garcia said that once installed, the screens should be maintenance free for 20 to 25 years.
The commission voted to send recommendation for approval of the purchase of copper coated water intake screens to city council.
The next item also concerned replacing equipment at Hillsdale Water Treatment Plant.
The plant uses a hoist/crane to install and remove submersible raw water pumps that are 50 feet deep in a wet well. The pump that the crane lifts and holds weighs 1.5 tons.
The existing crane is over 20 years old ,and it can only raise and lower. It’s a safety concern for plant personnel, who have to hold the raised pump with a chain to keep it from swaying in the breeze. In high wind conditions it becomes impossible.
Staff wants to buy a new crane from Konecranes for $42,995 plus taxes, freight and insurance.
The new crane has controls for raise and lower functions, rotating the jib, and trolley movement.
Staff advises it will be more efficient and reduce risk of personnel injury.
The commission voted to recommend city council approve the purchase of a new crane for Hillsdale Water Treatment Plant.
Underground electric cable
The commission considered a supply contract to purchase underground cable for the Circuit 41 Back Feed Project.
Bruce Baldwin, electric distribution manager, presented a summary.
The purpose of the project is to connect two overhead electric feeder circuits that “dead end.” Connecting those dead ends provides an ability to back feed in the event of damage to one of the circuits or a failure on the line or at the substation.
The new line will connect Circuit 42, which now ends north of 183rd Street, to Circuit 41 near the new Orscheln Farm & Home store on S. Gardner Road.
This will provide improved system redundancy and reliability, and will reduce the impact area and duration of power outage.
Most of this line will be installation of new overhead wire and poles, but two short sections at the connection points go underground.
This item is request to purchase 2,250 feet of Okonite 750 underground cable only. Three quotes were collected.
Staff recommended accepting the quote from Anixter Power Solutions LLC, in the amount of $35,437.50 plus taxes and shipping.
The commission voted to recommend city council approve the purchase of 2,250 feet of Okonite 750 underground cable from Anixter Power Solutions LLC.
Staff also summarized some recently completed projects:
• a 3 phase overhead line was installed on the 200 block of E. Main between N. Elm and N.Sycamore
• air spoilers were installed on overhead lines on 167th between N.Center and N. Wavery
• a single phase overhead line was rebuilt in the 600 block of E. Washington
• two new VFD rated pumps were installed at intake at Hillsdale Water Treatment Plant
• clean out of the sludge pond at Hillsdale has been completed
Krievins appointed to KMEA
The city of Gardner is a member city of the Kansas Municipal Energy Agency (KMEA) and as such is required to have two directors and an alternate on the KMEA board.
The commission needed to appoint a new director to replace Lance Boyd, who is no longer a member of the UAC.
The commission appointed Andrew Krievins as Director #1 representing Gardner on the KMEA board.
Krievins was attending his first meeting as a UAC member.
