Consolidated Demolition & Utility Improvements




Project Description: This project constructs facilities to reduce biosolids handling and disposal costs, replace aging sludge dewatering facilities, and provides associated odor control facilities. The project will demolish two obsolete digesters and several other facilities. The demolition site will receive extensive grading, drainage and paving improvements.

Background Information: This project will replace the dewatering facilities that have reached the end of their service life. Based on the Long Range Biosolids Master Plan, a newer dewatering technology will be utilized to reduce the amount of water in the biosolids hauled offsite to reduce biosolids management disposal costs.

Project Status: Construction began in Winter 2015 and is scheduled for completion in Summer 2020.
