Appendix_D_Recommended_Configuration.pdf

This is an Appendix document from Charles County, Maryland, detailing the recommended configuration for Aerated Sludge Holding Tanks at the MWWTP (Municipal Wastewater Treatment Plant). The document provides a technical schematic and legend identifying key components of the system, including Primary Clarifiers (PC), Secondary Clarifiers (SC), Final Clarifiers (FC), Gravity Thickeners (GT), Primary Sludge (PS), Waste Activated Sludge (WAS), and multiple Sludge Holding Tanks, with notation indicating that certain sludge holding tanks are currently offline. The configuration is designed to support the County's objective of achieving three days of storage capacity at 20 MGD Average Dry Flow (ADF).

The Board of Commissioners for Charles County is seeking qualified contractors to provide comprehensive services including preparation of contract drawings and specifications, acquisition of all necessary permits, and construction engineering services for the proposed aerated sludge holding tank upgrades. These improvements are essential to meet the County's operational requirements for expanded storage capacity while ensuring environmental compliance and readiness for future growth at the treatment facility.
