In January 2008 Hazen & Sawyer, an engineering consultant firm working for the Rivanna Water and Sewer Authority (RWSA), completed a report on the evaluation of the Camelot Wastewater Treatment Plant (Camelot WWTP). The report concluded that the existing operational configuration of the Camelot WWTP limited its capacity to 120,000 gallons per day (gpd). In addition, the components of the treatment facilities would need significant work to maintain their integrity.
Since the influent wastewater flow rate is already measured at 120,000 gpd, and knowing that approved development projects which were under construction would generate additional wastewater required to be treated at the Camelot WWTP, the RWSA and the Albemarle County Service Authority (ACSA) initiated capital improvements and operational revisions which would allow the facilities to handle the anticipated total wastewater flow. These improvements are close to completion, and in time to receive the additional wastewater flow.
In August of 1992, the ACSA and the RWSA entered into an agreement with some area developers which required that, when the Camelot WWTP reached 80% of capacity, the ACSA and RWSA initiate planning for the handling of wastewater generated in the area. In addition, the agreement also stated that when the Camelot WWTP reached a capacity of 90%, the ACSA and the RWSA would implement the proposed wastewater plans. With the requirements of the agreement, the limited capacity and structural deficiencies of the Camelot WWTP, and the proposed development within the Jurisdictional Area, the ACSA and RWSA initiated a long-term plan for the handling of wastewater in the Camelot area. Greeley & Hansen, an engineering consultant working for the RWSA, completed a study of alternatives for handling wastewater in the area. The recommended alternative included a regional pump station which would discharge wastewater to the wastewater collection system which serves the Moores Creek Wastewater Treatment Plant.
The ACSA met with area developers to assess the proposed development and proposed quantity of wastewater to be generated. In addition, the ACSA procured the services of Whitman, Requardt & Associates (WRA) of Richmond to prepare a Preliminary Engineering Report for the project. Based on the structural deficiencies of the Camelot WWTP and the proposed wastewater generation rates, a solution was required that could be designed and constructed within a two year period. The Preliminary Engineering Report was completed in December 2008, and included a recommended alternative which is comprised of a series of two pump stations and corresponding force mains.
One of the pump stations is anticipated to be located in the area of the Camelot WWTP, to transport wastewater from development north of the North Fork Rivanna River, to the south side, to a regional pump station. The Regional Pump Station will transport flows from the Camelot Pump Station, along with wastewater generated from the North Pointe Development and the North Fork Research Park, to the ACSA Wastewater Collection System, south of Airport/Proffit Road. The Camelot Pump Station will be sized to handle wastewater generated from the existing development area and proposed development area boundary, as depicted on the Places 29 Master Plan.
In December 2008, the ACSA Board of Directors appropriated $840,000 toward the final engineering design of the proposed project. WRA has reviewed the proffers requiring the North Pointe Development to make substantive roadway improvements along Route 29 South, and has completed an analysis of the location for the Regional Pump Station Force Main. Representatives of the North Pointe Development have been very helpful in assisting WRA and the ACSA in evaluating the route of the force main.
We anticipate completion of final engineering design by December 2009 and completion of construction by January 2011. The estimated cost of the current project is approximately $11 million. The ACSA is currently evaluating funding alternatives for this project.
I look forward to discussing the project with you at the meeting on March 4, 2009.
