Hydraulically monitored all 15" and larger collection lines and major pump stations, using XTRAN-SWMM model developed by the US EPA. Calibrated system dry and wet weather flows to measure flows. Predicted future wastewater projects and entered them into the model. Analyzed system capacity on a per pipe basis. Evaluated construction options and recommended future construction.

Lancaster County, South Carolina Sewer Feasibility Study

Evaluated the need for pump stations and force mains in regions where gravity sewer is impractical, and determined the potential customer base to be served with the extension. Design assistance and permit coordination of multiphase sewer expansion for Lancaster County Water and Sewer District. Design included layout of force main, pump station, and 167,000 LF of gravity sewer lines extending from existing and proposed outfalls. Also evaluated the need for pump stations and force mains in regions where gravity sewer is impractical, and determined the potential customer base to be served with the extension. Duties included plan design, pump station calculations, and preparation of contract and bid documents.

Lillington, North Carolina, 201 Wastewater Treatment Facilities Plan

Prepared an Environment Assessment and a 201 Wastewater Treatment Facilities Plan. Feasible alternatives were evaluated and the most cost effective solutions for the Town of Lillington to serve the future capacity and treatment needs were determined. Preliminary designs and cost estimates of tertiary treatment with filtration and ultra-violet disinfection, constructed wetland treatment following secondary treatment, and land application of treated wastewater were considered. User charges were analyzed to determine the impacts on the typical user of the system. The recommended alternative was to expand the wastewater treatment plant to 1.5 mgd with flow equalization, preliminary treatment, extended aeration oxidation ditches, clarifiers, tertiary filtration and ultra-violet disinfection.

Lumber River Council of Governments, Lumberton, North Carolina Regional Consolidation Wastewater Study

Completed a study of regionalizing wastewater facilities in Bladen, Columbus, Hoke, Scotland, and Robeson County. Project included the examination of problems of wastewater discharge and treatment within several sub-basins of the Lumber River. Focused on determining opportunities to develop a regional or series of sub-regional wastewater systems, thereby eliminating a series of problems throughout the county, including Special Orders of Consent, infiltration and inflow problems, and various other permitting issues. Project involved 28 units of local government, ten industries, a regional airport authority, a public school system and other parties interested in promoting economic development.

Moore County, North Carolina, 201 Facilities Plan

Prepared a 201 Facilities Plan Update for expansion of regional wastewater treatment facilities. Study included evaluation of future flows, treatment alternatives, sludge handling and disposal alternatives, cost estimating, and preliminary design. The study evaluated the feasibility of extending service to other areas within the County and required coordination and information collection from the various municipalities currently discharging to the Regional WWTP. Population and flow projections were completed for each service area to determine future loadings and treatment requirements.

Monroe, North Carolina Water and Sewer Annexation Evaluation

Evaluated scenarios to provide sewer and water services to annexation to the city. Evaluated routing alignments, right of way, size of annexation and population in the annexed area and measures to best serve those customers. Project resulted in approximately 21,000 LF of gravity sewer lines.
