Wastewater system master plan will be used for annual capital improvement plan development.

​Winston-Salem / Forsyth County Utilities Commission

Black & Veatch completed a wastewater collection system master plan for the Winston-Salem/Forsyth County City/County Utility Commission (CCUC). The results of this project will be used to plan future capital expenditures.

Overview

The 30-year wastewater system master plan will provide the necessary tools for annual capital improvement plan (CIP) development, and it will offer ongoing capacity analysis of the wastewater system. The task included the traditional master planning elements, such as projecting system growth and flows, and conducting hydraulic modeling to assess system capacity. The analysis also determined future infrastructure improvements needed to convey projected dry and wet weather flows. In addition, various asset management assessments were conducted to provide a holistic CIP solution.



Primary tasks of the project included:


  • Historical growth analysis and growth projections.

  • Dynamic hydraulic model and system capacity analysis fully calibrated to observed flow and rainfall data.

  • Asset management assessment using PAS 55 and asset evaluation.

  • Lift station condition and risk assessment.

  • Development of rehabilitation and replacement projects.

  • Provision of a GIS-based interactive CIP tool integrating system piping and facilities with CIP projects.

  • A gap analysis that provided a number of recommendations for CCUC to consider in improving the overall collection system.

Results

CCUC now possesses a detailed master plan that will more easily map out future capital expenditures and help ensure funds are expended in the best manner.
