ANDERSON — The city will dedicate the upgraded facilities at the Water Pollution Control Plant, 2801 Gene Gustin Way, at 9 a.m. Wednesday.

Mayor Kris Ockomon will participate in the ceremony. Tours of the plant will be given for visitors following the dedication.

This project to rehabilitate the 30-year-old effluent filters allows the city to meet current compliance requirements to eliminate the plant’s effluent filter bypass.

The project improved safety, ease and reliability of filter operation and maintenance at a much lower capital cost than building new filter facilities at the plant, the city said in a press release.

Upgrades were made as part of the $3 million project, which was constructed without a rate increase, include:

— Converting the water-only filter backwash system to a simultaneous air/water backwash

— Using a more effective coarse sand filter media, replacing hydraulic oil actuators with safer electric actuators

— Upgrading the previous controls for the backwash system.

In addition to providing greater operational flexibility and reducing maintenance, the rehabilitated effluent filter facilities are to provide more dependable filtration under both dry and wet weather flow conditions to maintain effluent quality to meet permit limits.

The upgraded facilities have also increased filtration capacity, which will allow the city to meet the future needs for its Combined Sewer Overflow Long-Term Control Plan.
