Synthetic ‘pigs’ for sewer cleaning to be launched to Monett

Pigs will fly in Purdy.

During a special city council meeting last week, aldermen approved building a “pig launching and receiving station,” one of three changes orders to the sewer pipeline project to Monett’s wastewater treatment plant.

Mayor Bo Prock explained the “pig” in question will not be the pork variety, but instead it will be a foam disc. The new east lift station will be equipped with additional ductile iron pipe, fittings and a pressure gauge to launch the disc like a rocket into the sewer line to scrape the edges, removing potential debris build-up. The receiving station will be built at the Monett end at the wastewater treatment plant.

“City personnel will be trained on how to operate the pigging system and the new pressure line shall be pigged with a bare swab upon completion of the project,” the change order with Rosetta Construction stated.

City Clerk Debbie Redshaw said in case of more significant problems, city staff could launch a block of ice shaped like the disc or something like a Brillo pad that would melt by the time it reached Monett.

“We talked about [launching the pig] every six months,” Prock said. “They thought yearly would be fine.”

The pig system was added at a cost of $23,000.

For improved maintenance, several other changes were made to the construction project following the pre-construction conference. These included adding a venting system at the east lift station and the valve vault for $1,485 to release sewer gasses plus more vents at both flow meter vaults for $970 to reduce corrosion and eliminate the build-up of sewer gas. Adding two check valves with two backflow meters to reduce sewer gasses was included at no additional cost.

Other changes included the addition of a pipe restraint made of a concrete saddle block near the receiving manhole at the Monett wastewater treatment plant to reduce the water hammer effect for $750. Aldermen agreed to add a sampling station in the meter pit for easier access for $625.

All those changes boosted the cost of the construction contract by $26,830, making the new total $1,844,723, still well under the second lowest bid of $2,259,727.18 from Southard Construction of Joplin.

The rest of the meeting focused on passing a budget for the fiscal year starting July 1.

Projections called for an 8 percent reduction in income, mostly from a 30 percent reduction in fines and forfeitures from the municipal court. City Clerk Debbie Redshaw said no raises were planned due to the implementation of the LAGERS state retirement system. Total spending on salaries was up by $100 while payroll taxes were projected at $1,000, down over $14,000 from the previous year.

Spending on general operations was projected at $48,060, which included $7,910 in capital improvements as aldermen discussed purchasing a tractor that could be used for brushhogging at the lagoon. The total was close to the spending sum two years ago, but $19,000 under last year.

Total spending on the police department was listed at $99,970, down by about $600 from the previous year. Wages were expected to drop by $5,000. The budget included $2,500 for new equipment after budgeting none the previous year.

Municipal court costs were projected at $31,470, up nearly $3,500 from the previous year. Payroll taxes of $1,530 were added after paying none the previous year, while health insurance spending was expected to rise by 78 percent.

Sanitation is expected to cost $50,400 in the new year, up by more than $2,000. Spending on the park is expected to total $5,000, up $500 from the previous budget, mostly due to a boost in rental expenses.

Redshaw anticipated the city would spend more on streets in the coming year, another expense that comes from the city’s general fund.

Running the water system is expected to cost $233,650, a drop of almost $50,000 from the previous year while sewer costs dropped by $8,000. The reduction stemmed from lower charges for professional services as the city moves past the implementation of having Utility Services converting the system to radio-read meters. Cost for meters was split between and water and sewer departments. No rate increases were budgeted for water or sewer as the sewer pipeline installation began.
