Iron Bridge Wastewater Plant Improvements

This project will upgrade electrical services and equipment at the Iron Bridge Regional Water Reclamation Facility.

Improvements include:

• Replacement of Deep Bed Blower building's service switchboard
• Upgrading the Wetlands building's service
• Upgrades to services at the Maintenance, Warehouse, and Administration buildings
• Portable generator access connections improvements
• Service upgrades at Solids and Digester buildings

This project involves upgrades to the existing biosolids dewatering system.

Upgrades include:

• Replacement of three existing 2-belt filter presses with two 3-belt filter presses with polymer feed and wash water pumps
• Replacement of existing Gravity Belt Thickener (GBT) feed pumps
• Electrical and instrumentation upgrades for both the new and existing 3-belt filter presses

The grit system replacement project will result in the design and installation of new grit removal equipment, new yard piping and a return activated sludge (RAS) blending box to mix the RAS with the degritted flow. The design will include a new flow control system to equalize influent flow.

Project consists of installation of an outside air ventilation system to improve the air quality and reduce the humidity in the sludge press room.

Installation includes:

• Two-speed ventilation fans
• Press room cleaning and painting
• Discharge air stacks to dilute odorous air discharges
