Charlotte Water (CLTWater) is the largest water and wastewater utility in North Carolina, serving approximately 311,000 customer accounts. The agency owns and operates multiple water treatment plants, wastewater treatment plants, lift stations, and extensive water and sewer lines throughout Mecklenburg County.

CLTWater requires consulting engineers to assist with various on-call projects related to the infrastructure described above. These projects are often small in scope and typically require immediate attention. Because these services are on-call, companies should be able to provide engineering design and construction support within 48 hours of receiving notice.

CLTWater will review qualifications and select qualified on-call consultants for the specialties listed in the following paragraph. CLTWater does not expect Proposers to submit qualifications for all specialties.

Charlotte Water will select Companies for the following on-call specialties:

  • Industrial and commercial electrical engineering, analysis, generation, and distribution
  • Water and wastewater conveyance systems analysis, system modeling, planning and engineering
  • Water and wastewater treatment plant engineering
  • Structural engineering
  • Civil/site engineering
  • Building engineering – plumbing, HVAC, roofing systems, fire suppression systems and architectural services.

Owner’s Advisor for the Lee S. Dukes WTP Expansion

This Contract will be for Owner’s Advisor services the upcoming design and subsequent construction of the proposed Lee S. Dukes WTP Expansion and associated infrastructure projects. The Owner’s Advisor professional services will start during procurement and continue through construction/warranty phases of infrastructure associated with the Lee S. Dukes WTP Expansion project.

Progressive Design-Build Services for Lee S. Dukes WTP Expansion

This Contract is for the design and construction of the Lee S. Dukes WTP Expansion project. The first phase of this project will include the start-up of a new 18 MGD conventional treatment train and additional associated structures, processes, and appurtenances, including residuals basins, high service pumping, clearwell storage, and standby power. The Design-Builder will work with Owner and Owner’s Advisor to determine the treatment processes, final layout, sizing, and specific facilities to meet the Owner’s goals for this project. The Design-Builder will provide the resources and staff to deliver the final project that will include, but not be limited to: Facility Planning and Preliminary Design, Permitting, Detailed Design, Cost Estimating, Construction, Start-Up and Commissioning.

FY2026 and FY2027 Various Storm Water Services Projects

The following is a general description of the Scopes of Service included in this RFQ. The selected firms will use HEC-HMS, HEC-RAS, and/or a hydraulic grade line closed system computer model, or an approved alternative (SWMM) method. All methods will be in accordance with the Charlotte-Mecklenburg Storm Water Design Manual. The City’s then current AutoCAD standards will be used for production of all plans and profiles.

 

Work will be issued via written Task Orders, which will specify the requirements of the various projects. Multiple Task Orders may be issued for each project. Multiple Task Orders may be issued at once.  The City of Charlotte reserves the right, upon successful completion of a given Task Order, to issue subsequent Task Orders to the same or a different Company.

 

The below list provides a general list of the tasks required. Task orders may include any of the following:

 

  • Surveying, utility locating, and PACP stormwater asset inspections.
  • Existing and Proposed Conditions Analyses
  • Channel Stabilization and/or Restoration
  • Utility Coordination
  • Easement/Plat Preparation
  • Public Engagement
  • Preliminary and final design
  • Permitting/Encroachments
    (404/401, NCDOT, Railroad Agencies and FEMA Floodplain Development Permitting)
  • Preparation of Construction Documents (Plans, Specifications, and Cost Estimates)
  • Bid and Construction Phase Services
  • Geotechnical and Structural Engineering Services

 

The city anticipates selecting multiple firms to provide these services. These will be drainage area-based storm drainage improvement projects that involve differing land uses within the project areas. Drainage basins may include closed and open systems. The study areas may be on a portion of the watershed or the entire watershed. Task orders may be issued for multiple projects at once. Upon satisfactorily completing a task order, the City may issue additional task orders. Scoping on these projects is anticipated to begin in early 2026.

McDowell Creek Capacity and Enhancement Program

This project will increase treatment capacity at the McDowell WRRF. Work will include but is not limited to designing a new BTB, RAS and WAS pumps, a new RAS distribution box, new hydro cyclones, and improvements to the blower building.

Mallard Connector Main

This project provides increased hydraulic capacity to the Mallard Tank, which will enable it to trend better with the Huntersville Tank. This will eliminate the need to throttle inlet valve at Huntersville Tank, which will result in energy savings by reducing discharge HGLs at pump stations. It will also provide higher capacity for water to be leaked through the Mallard PRV from the 978 into the 882 in emergency scenarios.

Statesville Road Booster Pump Station

The goal of this project is to design a booster pump station along Statesville Road. The booster pump station will have a capacity of roughly 25 MGD. The purpose will be to pump into the 978 zone, providing additional capacity. The selected firm will handle design services, permitting, and construction admin services.

Industry Day Event: Bryant Farms Road Extension Phase 2 – Progressive Design-Build

The City of Charlotte invites interested firms to participate in an Industry Day for the Bryant Farms Road Extension Phase 2 project. This session will provide an overview of the project scope, schedule, and goals, as well as information on the City’s plan to use the Progressive Design-Build (PDB) delivery method in accordance with N.C.G.S. § 143-128.1A.

Participants will learn about:

      • Opportunities for collaboration and Charlotte Business Inclusion (CBI) participation

A Q&A session will follow the presentation.  All questions and responses will be published on the city’s procurement website to ensure transparency.

Who should attend: Design-Build firms, contractors, designers, and subcontractors interested in teaming opportunities for this project.

Event Date/Time: Monday, November 17, 2025, 10 AM to 12 PM

Event Format: In-person only

Event Location: Charlotte-Mecklenburg Government Center Room 280

About the project: The purpose of the Bryant Farms Road Extension, Phase II project is to continue the street connection of Bryant Farms Road between Rea Road and Ardrey Kell Road. The design is anticipated to include a two-lane road with turn lanes, shared-use path on both sides of the road, and improvements at the intersections of Bryant Farms Road with Rea Road, Tom Short Road, and Ardrey Kell Road. The project will also build a crossing over Flat Branch stream and will run adjacent to the Flat Branch Nature Preserve for a portion of the project.

Statesville Road Booster Pump Station

The goal of this project is to design a booster pump station along Statesville Road. The booster pump station will have a capacity of roughly 25 MGD. The purpose will be to pump into the 978 zone, providing additional capacity. The selected firm will handle design services, permitting, and construction admin services.
