(Harrisonburg, VA) CCG was responsible for the design of a 36” diameter, 30 million gallon per day temporary sewer bypass line in conjunction with the construction of the new North River Wastewater Treatment Facility in Harrisonburg.

(Botetourt County, VA)  In 2007, CCG was awarded an on-call contract with the County of Botetourt.

(Roanoke County, VA)  CCG was awarded an on-call contract for civil engineering and design services by Roanoke County. Work for this contract is forthcoming.

(Botetourt County, VA)  CCG provided sewer system review and enhancement cost study for 5,000 lf of 8” sanitary sewer. Study was precipitated by proposed development. Options included replacement and re-lining. Project was preformed as part of an on-call contract with the County.

(Fincastle, VA)  Staff member served as Project Manager and Lead Engineer for a new package-type wastewater treatment plant in Fincastle, Virginia. New plant prompted by new regional jail. Existing lagoon type plant rated at 75,000 gpd. New plant rated at 125,000 gpd to accommodate additional jail wastewater and development around town. Plant designed with biological nutrient removal (BNR) due to strict nitrogen and phosphorous limits within Chesapeake Bay Watershed.

(Charlottesville, VA)  Staff member served as Project Manager and Lead Engineer responsible for the preparation of SewerCAD computer models with Infiltration/Inflow and capacity analyses for three separate sewer collectors: 17,000 LF with over 100 manholes, 7,000 LF with over 50 manholes, and 10,650 LF of sewer line with over 50 manholes. Pipes ranged from 8″ to 36″ in diameter. Utilized SewerCAD software to model pipe flows using system data gathered by City, including flow data. Developed statistical relationship between rainfall depths and peak flows measured in system. Correlated rainfall depths to return periods and peak flows to determine how often overflows would occur. Developed matrix showing when each section of sewer is taxed beyond its capacity. Also created future scenarios using general growth plus new facilities planned by the University of Virginia. Developed a phased plan with recommended line size increases and prepared an implementation schedule with cost estimates. The Models’ findings were compared to observed problems in field and matched very closely. Recommendations from the models are presently being implemented with replacement lines under construction.

(Vinton, VA)  Staff member served as Project Manager and Lead Engineer for Infiltration/Inflow analysis of fifty year old subdivision. Most of the lines were clay pipe and manholes were brick. Flow measuring devices were inserted and data was analyzed to determine relationship between rainfall and flow. Results were used in conjunction with smoke testing and video reconnaissance to prepare rehabilitation plans. Study led to replacement and lining of 10,000 lf of the system.

(Rockinham County, VA)  Staff member served as Lead Engineer for analyzing several adjacent sewersheds in a rapidly developing part of the County. The total area exceeded 2,800 acres. The County’s comprehensive plan was utilized to determine development densities and this information was used to predict future flows. Several existing pump stations were constructed by developers. These had become maintenance problems for the County. Part of the study included developing a three-phase plan for eliminating several pump stations by building new gravity sewers that could serve existing areas as well as future developed areas. Phase I of this study has already been designed and constructed. The study also analyzed different methods that the County could use to secure reimbursement of sewer construction costs from developers.

(Marion, NC)  Staff member served as Lead engineer with responsibility of designing 46,000 LF of gravity sewer based upon field reconnaissance and surveys. Existing septic fields had failed in the economically depressed area. Sanitary sewer was needed for public health reasons.

(Monterey, VA)  Staff member served as Project Manager for the development of a Preliminary Engineering Report and Environmental Report for a new wastewater treatment plant (120,000 gpd). Reports submitted to the Department of Environmental Quality and U.S.D.A. Rural Development. Preliminary Engineering Report was used to secure $1.5 million in grants and $500,000 in low interest loans.
