More lights out for now at Pattonsburg After a couple of break-ins were reported on South 5th Avenue, residents asked the Pattonsburg’s aldermen about getting some lights in the area. In November, the board requested Farmers Electric Cooperative (FEC) to visit the town to see if it would be feasible to put more lighting along Hwy. C to Hwy. 69 and along Hwy. 69 south to Oak Street. At the Dec. 11 public meeting of the aldermen, an FEC representative informed the city that the price of the lighting could range from $150,000 to $175,000 plus the light study and labor. The aldermen tabled this subject until a later date. In other business at the December meeting, Brandon Tritton with JB-LB Insurance presented the renewal quote for the city’s insurance. The board re-

newed the policy, and added the terrorism package on as well. The city’s lagoon fence was damaged. Law enforcement was notified and arrived and took a report, but said the city would have to file a civil suit. Bob Hildreth, the city’s water superintendent, said the fence would cost approximately $350 to fix. The board decided to repair the fence with no legal action. Last month the board asked Mr. Hildreth to check on the drainage problem on the east side of business buildings to see what needs to be done and get an estimate on what it would cost. Aldermen approved the cost estimate of $261 for repairs. The board amended an ordinance to: authorize keeping of animal records on behalf of the city by a single contracted facility; revise the length of time re-

quired for holding a dog or cat in impoundment when a known owner has been notified, according to the current state standard. Lucille Lusk with Municipal Assistant Company presented a tracking report. The above is taken from the unapproved minutes of the meeting of the Pattonsburg Board of Aldermen held Dec. 11. Those in attendance were Mayor Edmon Howard; board members Lonnie Luke, Sandra Woodring, Dustin Sperry (Kelly Hughes was absent); Water Superintendent Bob Hildreth; City Clerk Karen Shepherd. Guests were Lucille Lusk, STCB/MAC; and Brandon Tritten, JB-LB Insurance. Note: At the August meeting of the Pattonsburg Board, Kelly Hughes was appointed as a board member until the next available election.

Don’t miss this library display

This beautiful hexagonal crystal quartz is on display at the Daviess County Library. It was found in a cave by Michael Comstock. Mr. Comstock will reveal only that it was found in Daviess County. The plaque reads: Quartz is a common mineral and has a variety of colors. Each color has its own name associated with it, such as amethyst, which is a purple color. Smoky quartz refers to a brown color and rose quartz is a pink color of quartz. Quartz has a hardness of seven on the Mohs hardness scale (a diamond’s hardness is 10) and has a specific gravity of 2.65.

Progress continues on Gallatin’s water treatment plant

The weather has cooperated wonderfully and the work on Gallatin’s new water treatment plant is now three-quarters done. March of next year is the target date for completion, and it looks like that goal will be easily reached. The majority of the outside construc-

tion work is complete at the plant. The work is being done by David E Ross Construction Company, which bid $4,987,000. The work that remains, according to City Administrator Tony Stonecypher, is inside work and is not weather dependent. That work will consist of installing electricity and plumbing and control panels.

Understanding the water treatment process reveals how raw water becomes safe, clean for consumption

The Gallatin Water Treatment Plant (WTP) is a lime-softening process, which means hardness in the water is removed from the water through the addition of lime. Lime softening is a common treatment for groundwater. Gallatin’s water source is groundwater from three wells located approximately three miles east of Gallatin along Highway 6. Once the groundwater is pumped to the treatment plant, complete lime softening WTP stages include aeration, coagulation /flocculation/sedimentation, recarbonation, filtration, and disinfection. The following provides a brief description of each stage: Aeration The incoming raw water is cascaded through an aerator to strip dissolved carbon dioxide (CO2). Stripping the CO2 lowers the amount of lime required later in the treatment process.

Landscaping dirt, dredged from Lake Viking, was provided at no cost to the city beyond transportation expense. The dirtwork will be sewn with grass. Concrete backwash basins are used to clean the filter media in the filtration stage. Backwashing consists of periodically pumping water backwards through the media so that it can be reused. The by-products from the lime softening process, or sludge, are piped to the drying lagoon at the bottom of the hill.

Coagulation/Flocculation/Sedimentation Following aeration, the water is routed to a solids contact clarifier for hardness removal. Lime and the coagulant aluminum sulfate is added and the water is gently mixed, aggregating the small precipitated particles together to form larger precipitates called flocs (flocculation). Once large enough, the flocs settle by gravity to the bottom of the clarifier and are removed (sedimentation).

Recarbonation After adding lime, treated water will generally have a pH greater than 10. It is necessary to lower the pH to stabilize the water and prevent deposition of carbonate scale on distribution piping. Recarbonation is achieved through the addition of CO2, a common process used to reduce pH. Filtration Following recarbonation, filtration removes any unsettled lime floc and other partials that may be present in the treated water. Disinfection Chlorine is added to the water to eliminate any remaining pathogens. Clear Well Once treated, the water is routed to a clear well onsite, which is a large concrete storage tank. Water in the clear well is pumped to the existing 250,000 gallon water tower, located on the western edge of town, and then routed through the existing approximate 45 miles of distribution main to the City’s end users.

The water lime bin was erected last week at Gallatin’s new water treatment facility.
