Utility Services Wastewater Treatment Systems

Thompson Engineering is providing engineering services to address issues for a consent decree for 17 different wastewater treatment plants located throughout the State of Mississippi. The consent decree outlines tasks that are to be accomplished within certain time frames at each of the facilities.


The tasks Thompson Engineering is responsible for include:


  • Comprehensive Performance Evaluation (CPE) and Composite Correction Plan (CCP) programs evaluating each wastewater treatment plant. These plans were evaluations of the design of the plants and upgrades to meet current design standards.
  • Design of Sewer Overflow Response Program (SOFRP) to ensure every report of a sanitary sewer overflow (SSO) is dispatched to the appropriate response personnel so that the effects of the overflow can be minimized with respect to adverse effects on public health, the environment, and property.
  • Emergency Operations and Maintenance Plan (EOMP) serves as a guide to the response of management and staff in responding to an emergency event.
  • Training Program to provide for the operation of both wastewater collection and wastewater treatment systems.
  • Information Management System (IMS) program provided documentation concerning the existing IMS used to track and evaluate operations, maintenance, customer service, and utility planning.
  • Financing and Cost Analysis Program (FCAP) included a summary of significant capital improvements and projections of capital expenditures required over the next five years. It also included an analysis of life-cycle costs for equipment and structures.
  • Pump Station Operations Program (PSOP) contained a pump station inventory, procedures to help prevent pump station failure, and an emergency pump station operations plan to include auxiliary power, pumps, and contingency plans.
  • Gravity Line Preventive Maintenance Program (GLPMP) contained an analysis of routine cleaning programs, root control programs, and manhole preventative maintenance.
  • Pump Station Preventive Maintenance Program (PSPMP) contained an electrical maintenance program, mechanical maintenance program, physical plant maintenance program, and a pump station repair program.
  • Sanitary Sewer Overflow Plan (SSOFP) contained maps of the location of SSOs, evaluation of recurring SSOs, and prioritization of remedial measures to eliminate recurring SSOs.
  • Fats, Oils and Grease (FOG) program consisted of a public education program with the objective of educating customers on the hazards of FOG clogs in the sewer system and taking preventive measures to effectively reduce the occurrence of such cases and thereby comply with U.S. EPA regulations.
