Council OKs wastewater bid

Sletton Construction will upgrade plant for $26.2 million

KINGMAN - The city of Kingman is expanding ... its wastewater treatment plant. The City Council awarded the contract for the upgrade and expansion of the Hilltop Wastewater Treatment Plant to Sletton Construction during Monday evening's meeting.

City engineers estimated the cost of the project at $31.7 million. The city got 10 bids on the project. Sletton's $26.2 million bid came in at 17 percent below the estimate.

"This is a big deal for us," Councilwoman Janet Watson. "We want it to be perfect."

Part of the cost of the improvements will be covered by a loan from the Water Infrastructure and Finance Authority of Arizona.

The city has been working with the Arizona Department of Environmental Quality to upgrade the plant for several years.

The city plans to expand the plant, adding an oxidation ditch, which will help to denitrify the water after treatment, said Jeff Corwin, city wastewater superintendent. This will provide a better quality of effluent water to recharge the local aquifer.

The changes will also increase the amount of wastewater the plant can treat from 1.5 million gallons per day to nearly 5.1 million gallons per day.

The city expects it to take between one and a half to two years to complete the project.

Council also tabled discussion of an increase in the per diem rates to house prisoners at the county jail for another meeting. The city has an intergovernmental agreement with the Mohave County Sheriff's Office to provide housing for city prisoners. The agreement is due to expire on June 30. The city is expecting the per diem cost to increase from $55 per prisoner per day to $58.

The Western Arizona Council of Governments will also have another home for its Head Start program. Council approved WACOG to occupy a city-owned property on Spruce Street for a Head Start educational and meal preparation facility for five years. WACOG has a similar facility at Hubbs House, also owned by the city, on Golcondia Avenue.

Walgreens will also be able to tap directly into an existing sewer main along Andy Devine Avenue for its new store instead of building 300 feet of sewer line along Broadway Avenue.

Council also appointed John Kirby, Daniel Del Monaco, Christine Cerny, Lynne Petersen and Bill Goodale to the Economic Development and Marking Structure Workgroup. The workgroup is designed to study ways to promote and market Kingman.
