Motley’s new water treatment facility up and running

Graupman, who was in charge of the preliminary report as well as the project’s design, also served as construction manager. “Everything is coming out as planned,” he said. “Everything is within budget and there are no overruns.”

Tours of Motley’s new water treatment plant, located at the corner of 3rd Ave. So. and Cemetery Rd., were held Oct. 29.

A number of people were in attendance to learn more about how the facility works; and to enjoy refreshments in celebration of the completed project.

“Everything went great,” John Graupman, engineer with Bolton & Menk, Inc., said of the project. “The plant has been up and running since May and Bruce
 
Brotherton (the city’s public works supervisor) has been running it very well,” he added.
 
Graupman, who was in charge of the preliminary report as well as the project’s design, also served as construction manager. “Everything is coming out as planned,” he said. “Everything is within budget and there are no overruns.”
 
Originally estimated to cost $5 million, the total construction cost came in at $3.13 million. Bolton &
 
Menk, Inc., out of Mankato was the consulting city engineer for the project; and the general contractor was DiMar Construction out of Excelsior.
 
The project had been driven by aging facilities (the former water treatment facility had been built in 1992), water quality; and increased water demands by residents and the city’s major industries.
 
Comparing water samples John Graupman (left), engineer with Bolton & Menk, Inc., out of Mankato; and council members Steve Johnson and Amy Hutchison, compare water that has gone through the filtration process at Motley’s new water treatment plant to a sample of water that still contains manganese particles and iron. The filtered water is clear and the unfiltered is brown in color.

As was noted in a handout at the tour, “The City of Motley retained Bolton & Menk, Inc. to design and construct a water treatment system to meet the current and future demands of the city.
 
The existing water treatment facility was used to remove iron and manganese from the raw well water supply. A new treatment facility was needed because the existing facility was not capable of reliably meeting the necessary water demands of the city and local industries.”
 
Included in the handout was a description of the new facility and how it works.
 
The new water treatment facility has an average capacity of 600,000 gallons per day. It consists of a three step process of aeration, detention and filtration for iron and manganese removal.
 
Inside the facility is a motor control center, chemical feed system, air wash blower, high service pumps, filters; and a supervisory control panel.
 
Operation of the wells (located on the south end of town), the treatment plant and the high service pumps is automatically controlled by Allen Bradley Programmable Logic Controllers (PLC’s). The PLC includes an operator interface which allows staff to monitor and control the treatment system. All alarms are sent out to the duty operator by an automatic telephone dialer.
 
Looking at the clearwell John Graupman, engineer with Bolton & Menk, lifts the cover to the 100,000 gallon clearwell, a storage tank which holds water that has gone through the filtration process. From here, the water is pumped out (via high service pumps) to the distribution system. Graupman noted that the water in the clearwell is so clear you could see a quarter at the bottom of the tank and know if it were ‘heads’ or ‘tails.’ Also pictured are, from left, Christi Allen, Chris LeGendre and Carla Hoelscher, employees at Trident Seafoods in Motley.

Bruce Brotherton said he’s been very happy with the new facility so far. “We went online May 8, and we’ve never had to go back.”
 
He stops by once a day to take water samples, Brotherton said.
 
The new water treatment plant is much easier to operate than the old one, Brotherton said. “It’s more automated,” he added.
 
With a design life of 20 years, the facility is estimated to serve the City of Motley until 2035.
