PROJECT DESCRIPTION

The Union PSD operates two (2) wastewater treatment plants. Thrasher performed a facility study of the 40th Street wastewater treatment plant ‐ an extended aeration treatment plant operated in the contact stabilization mode, which was built in the 1960’s and upgraded in 1991.

The 40th Street wastewater treatment plant was properly maintained, however during the investigation and study phase of the project, it was determined some of the wastewater equipment had come to the end of its useful life. It was also determined that this plant was in need of an increase in its capacity due to the commercial and residential growth in the area.

Upgrades to the 40th Street wastewater treatment plant consisted of replacing two (2) influent pumps, constructing a new screening and grit removal system, two (2) new contact stabilization tanks, four (4) new clarifiers, new sludge return pump station, a new office building, upgrading non‐potable water system, demolishing existing office building, constructing new office building/garage, structural repairs to existing contact stabilization tanks, site work, piping, concrete electrical and mechanical.

Tyler Mountain Extensions

Also included in the project were gravity system extensions to the Big Tyler Mountain and Little Tyler Mountain areas, consisting of approximately 3 miles of pipeline for each extension.
