Coon Rapids launches new well rehabilitation program
The city of Coon Rapids has kicked off a new five- to six-year well rehabilitation program.
Back in 2001, the city launched a comprehensive well rehabilitation program which continued through 2007, in which all the city’s 25 wells and boosters pumping systems at both treatment plants were rehabilitated.
Then in 2011, the Coon Rapids City Council contracted with Progressive Consulting Engineers (PCE) to evaluate the city’s water production system and develop a program for continuous monitoring and maintenance.
That’s what this new program will do over the next five to six years with four to six wells being rehabilitated each year, according to Public Works Director Tim Himmer.
“As part of the city’s ongoing capital improvement program, it is necessary to continuously monitor the municipal water supply system,” Himmer wrote in a memo to the council.
The 2013 well rehabilitation will include work as wells 11, 14, 16 and 17.
Original plans included booster pumps four and five and the backwash recycle pump at the city’s west water treatment plant, but budget constraints have delayed those items, he wrote.
The major improvements completed on each well during the initial well rehabilitation program included rehabilitation of well pump houses, replacement of pumps and inspection of well casings and other major well components, Himmer wrote.
“At this time the well rehabilitation program will involve lesser amounts of work on each well, primarily focusing on inspections and required maintenance, as needed,” he wrote.
The council awarded a contract to E.H. Renner & Sons, Inc. for the monitoring and maintenance of wells 11, 14, 16 and 17 in the amount of $251,634.19.
According to Himmer, that’s more than the $220,000 allocated in the water utility fund for the project, but it is unlikely the total contract amount will be spent.
The base bid of $87,221 covers inspection, examination and testing the wells and equipment with the balance of $164,413.19 only necessary if something is found during the inspections that requires repair/and or maintenance of the equipment, Himmer told the council in his memo.
“Each alternate item that may require additional work would be reviewed and approved by the city and PCE staff prior to implementation,” he wrote.
And if the project cost exceeds the budget, staff will asked council to additional dollars to be appropriated in the water utility fund.
E.H. Renner & Sons was the lowest of three bids; the others were $307,635 and $292,395.
