Overview

Summary

The City of St. Petersburg is seeking bids from a qualified vendor to perform a partial filter media replacement at the Northeast Water Reclamation Facility (NEWRF), located at 1160 62nd Avenue NE. The project consists of removing, disposing, and replacing the top four layers of filter media within the existing filter beds, including approximately 30 inches of anthracite coal, 10 inches of filter sand, 2 inches of ¼” x ⅛” gravel, and 4 inches of ⅛” x 16 mesh. All existing lower gravel and underdrain tile systems shall remain in place and protected throughout the work.

This project is an interim rehabilitation effort to restore the performance of the existing filter station until a new parallel filter facility is constructed in the coming years. The work for this project will include removal, proper handling, disposal, and replacement of filter media in accordance with American Water Works Association (AWWA) B100 and MBM-S-100 specifications. The vendor will be responsible for furnishing all labor, equipment, materials, and supervision necessary to complete the project in a manner that maintains the integrity of the existing structure and minimizes operational disruption.

The City has intentionally not included cubic yard quantities in the solicitation. The dimensions and depths of the filter cells vary, and bidders are expected to determine quantities based on the as-built drawings and specified media layer thicknesses. To ensure accurate estimating, the City has provided the as-built filter drawings as part of the bid documents under Attachments . The vendor shall calculate the volume of each filter media layer based on the dimensions and the replacement depths provided in the Scope of Work. The inch measurements in the Scope represent the finished depth of the media layers to be installed, consistent with AWWA B100 and the project specification MBM-S-100, and are industry standard for defining filter media placement thickness.

Background

The Northeast Water Reclamation Facility (NEWRF) Filter Station is undergoing phased improvements to maintain treatment performance and operational reliability. A new, parallel filter station—designed as a mirror image of the existing system—is currently in design. Once that facility is constructed and placed into service, the existing filter station will be taken offline for full refurbishment, including replacement of all filter media and underdrain tile systems.

This interim project is limited to the removal and replacement of the top four layers of media in the existing filters to restore performance while maintaining continuous operations. The lower gravel and tile systems will remain in service and undisturbed until the complete rehabilitation phase begins following commissioning of the new filter station.
