Oakmont bridge work won't affect sewage plant

The upcoming Hulton Bridge replacement project won't affect operations at the Allegheny Valley Joint Sewage Authority's treatment plant in Harmar, which is upstream from the bridge.

Plant manager Rich Chiavaretta said future plant expansion might be necessary, but there's no impact now.

A new $80 million Hulton Bridge will be built on the side of the current span where the sewage treatment plant is located.

PennDOT hopes to begin the project to replace the 104-year-old bridge in August, and demolition of existing buildings near the bridge is due to take place this spiring.

A four-lane bridge and a pedestrian walkway will be built.

In other business

• The odor problem at the treatment plant has subsided, officials say. Officials had to find the right chemical combination to create bacteria in the digesters in the hopes of eliminating the odor, which has affected residents and businesses on both sides of the Allegheny River.

• The authority has no capital projects slated for this summer, but several minor projects are in the works.

Two pump station replacements are planned in Cheswick.

KLH Engineering will reconfigure one of the Cheswick stations that needs a wall replaced.

A cost estimate involving design fees and the scope of the project will be presented to the authority on April 24.

Equipment in the treatment area also needs to be replaced.

The authority earlier replaced pump stations along Guys Run Road in Harmar and on Colfax Street in Springdale.

• The authority is looking for a college-age student from Springdale Township to work at the plant over the summer. Applicants can contact the authority at 412-828-7227.

• The board hired Multi-Metals to install a safety railing along the skimmers to prevent falls into the sewage tank. The cost is $3,200.
