Summary
The purpose of this project is to rehabilitate or replace critical WTP components as identified through a condition assessment performed by Carollo Engineers, Inc. during the design phase of the 24th Street WTP Rehabilitation 2017 project. The following components require rehabilitation or replacement: flocculation basins, sedimentation basins, various concrete structures, filter valves, raw water inlet pipelines, sludge blowdown pipelines, main switchgears, and other electrical equipment.
