Engineering Services for Durbin Creek WRRF Expansion RFQ

Background
Renewable Water Resources (ReWa) is a special purpose district established in 1925 in Greenville, South Carolina, dedicated to enhancing community quality of life by transforming wastewater into renewable resources. ReWa serves over 500,000 residents across multiple counties and operates several wastewater treatment facilities.

The Durbin Creek Water Resource Recovery Facility (WRRF), constructed in 1986 and expanded in 2010, is set for further expansion to accommodate anticipated growth in southern Greenville County. The facility currently treats an average flow of 4 million gallons per day and is designed to meet future regulatory requirements for nutrient removal.

Work Details
The selected engineering firm will provide preliminary engineering services for the Durbin Creek WRRF Expansion project using a Construction Manager at Risk (CMAR) delivery method. Key tasks include:
- Reviewing prior engineering reports
- Performing flow and load analysis
- Requesting updated wasteload allocations
- Analyzing process alternatives considering project objectives and life cycle costs
- Recommending a final scope of improvements with phasing options
- Developing site layout and conceptual design criteria
- Conducting process and hydraulic modeling
- Preparing a Preliminary Engineering Report (PER)
- Advising on project risks and mitigation strategies
- Assisting with CMAR selection.

Additionally, the firm may evaluate the potential for constructing a new greenfield facility as an alternative to expanding the existing WRRF.
