Conway City Council has put its final stamp on the issuance of wastewater revenue improvement bonds and completed the process that will result in higher wastewater rates.

Conway Corp. officials have said a rate increase is necessary to fund construction of the $95 million Tupelo Bayou treatment facility along the Arkansas River in Lollie Bottoms.

The council on Tuesday night adopted an ordinance authorizing the issuance and sale of the bonds. The vote was 7-0. Alderman Jim Rhodes was absent.

Aldermen already had approved the proposed wastewater rate structure. City officials have said a survey found Conway’s current wastewater rates lower than in other parts of the state.

Rates will increase in three phases beginning this year. The increased revenue will be used to repay a loan from the Arkansas Natural Resources Commission, fund bond issue payments, support the decommissioning of the 30-year-old Stone Dam Creek treatment facility, pay for a new pumping station on the east side of the city, and provide "routine" capital improvements for the new wastewater facility.

The new treatment plant is expected to process 16 million gallons of effluent per day.

The average residential customer currently using 5,000 gallons of wastewater pays $19.32 per month. Under the new rate structure, the bill will increase 20 percent to $23.18 the first year; another 20 percent to $27.82 the second year; and 35 percent to $37.56 the third year.
