Influent Pump Station Wet Well Evaluation - Clayton, North Carolina
The influent pump station wet well at the Little Creek Water Reclamation Facility in Clayton had experienced significant concrete corrosion due to hydrogen sulfide gas attack. Concrete spalling had occurred and there was exposed aggregate throughout the wet well. To develop a recommendation for remediation, our team conducted an on-site inspection of the wet well with a structural engineering consultant. Findings from the investigation were evaluated and recommendations were developed to rehabilitate the wet well structure. A summary report was prepared and delivered to the Town that identified the existing wet well conditions, included our recommendations, provided documentation for alternative corrosion resistant liner solutions to prevent the problem from recurring, and included a cost estimate for fiscal year budgeting purposes.
New Water Treatment Plant Construction - Martin County Regional Water and Sewer Authority
After a 6-year study/planning/community outreach and design period, construction of the new raw water intake facility on the Roanoke River and new water treatment plant near Williamston, NC began. Complicating the project, there had been no previous water treatment plants in North Carolina designed and constructed to operate on a free flowing river this close to a salt water estuary. Construction of the 2 MGD water treatment facility to serve two eastern NC county water districts, as well as the Town of Williamston, included the raw water intake facility's two 2100 gpm pumps, approximately 1 mile of raw water transmission main, an eleven million gallon raw water reservoir with multiple pump facilities, up-flow clarifiers, high rate filters, 700,000 gallons of onsite finished water storage, and approximately 4 miles of new finished water transmission main. Our construction administration team provided contract administration and full-time on-site inspection over the approximately 2 year construction period that was completed in March of 2016 at a total project cost of approximately $27 million dollars.
Wastewater Treatment Plant Expansion Construction - Ahoskie, North Carolina
Winner of a 2011 Award of Excellence from the North Carolina Chapter of the American Council of Engineering Companies
The Town of Ahoskie's Wastewater Treatment Plant expansion was completed in March of 2011 and our team provided Construction Administration and Inspection throughout the duration of the construction process. The scope of our administration included coordination with the contractor to work through the project details and ensure completion of a quality product for our client. In doing this, we reviewing project shop drawings, payment requests and change orders, conducted project meetings and certified the project to the State. During observation of the construction we provided on-site resident personnel to follow the contractor’s work, help resolve conflicts or discrepancies, ensure substantial compliance with the design drawings and keep the client and engineering team informed of its progress. The result was an expansion from 0.901 MGD to 1.6 MGD capacity to provide for industries, public facilities and hospitals.
