BACKGROUND
This action will authorize a construction services contract with Ark Contracting Services, LLC, for the installation and rehabilitation of approximately 49,470 feet of water and wastewater main improvements at 20 locations. This includes the installation of approximately 800 feet of 6-inch, 20,200 feet of 8-inch, 110 feet of 10-inch, 200 feet of 12-inch and 1,930 feet of 16-inch water mains, and the installation of approximately 13,420 feet of 8-inch, 740 feet of 10-inch, 560 feet of 12-inch, 3,700 feet of 16-inch, 1,820 feet of 18-inch, 4,090 feet of 21-inch and 1,900 feet of 30-inch wastewater mains.
The existing mains targeted for replacement and rehabilitation were built between 1932 and 1986. These mains are contributing to an increase in maintenance costs, as well as service interruptions. The installation of the proposed segments will improve the capacity of the water and wastewater systems and reduce maintenance costs.
