The City of Zanesville is planning improvements to their 11-MGD design average daily flow wastewater treatment plant to improve operability, correct deficiencies in individual unit processes, and maintain compliance with the City’s combined sewer overflow Long-Term Control Plan (LTCP).
The LTCP required designing for a peak wet weather flow of 36.2-MGD through the Plant. Major operational problems included poor performance and high maintenance costs of the submersible primary pumping station, lack of redundancy in the headworks screening equipment, poor hydraulic performance and grit capture in the detritors, snail growth in the trickling filters with downstream accumulation of snail shells, aging solids handling equipment, and safety risks of the gaseous chlorine disinfection system.
CTI’s study addressed issues identified by Plant operators by prioritizing and budgeting improvements for development into construction packages in phases and areas of the plant. Conceptual designs are being developed to obtain operator feedback on proposed solutions before preparing construction documents.
