PARTIAL LISTING OF MUNICIPAL PROJECT EXPERIENCE

Town of Smyrna MS4 Storm Water Program and Utility Fee Development: Engineering services for the development and ongoing implementation of the “Six Minimum Measures” of the TDEC NPDES MS4 Permit. These services include the development of the storm water management ordinance, MS4 Ordinance, System Inventory of outfalls to identify Illicit Discharges and Detections, development of the Storm Water Utility User Fee Program, development of the Adjustments and Credits Policy, attendance of the Council Meetings to support adoption of Storm Water Ordinance, development of the Stream Buffer Ordinance, attendance of the Storm water Advisory Board to support storm water policies and decisions regarding adjustment and appeals of the storm water utility fees. Field reconnaissance, inspection and coordination of the stream outfall piping to implement within the Town’s GIS mapping system. Daily ongoing support of the MS4 Program and the Town’s staff to meet the requirements of the NPDES Permit.

City of Spring Hill MS4 Storm Water Program: Engineering services for the development and ongoing implementation of the “Six Minimum Measures” of the TDEC NPDES MS4 Permit. These services include the development of the storm water management ordinance, MS4 Ordinance, System Inventory of outfalls to identify Illicit Discharges and Detections, attendance of the Council Meetings to support adoption of Storm Water Ordinance, development of the Stream Buffer Ordinance. Implementation of the City’s GIS program and aerial photography. Daily ongoing support of the MS4 Program and the City’s staff to meet the requirements of the NPDES Permit.

Water Treatment Plant, Raw Water Intake Structure, and Raw Water Transmission Line (City of Spring Hill): Design of the project consists of a Raw Water Intake Structure located at mile 166 of the Duck River, the raw water transmission line consisting of approximately 35,000 linear feet of 18-inch ductile iron pipe, and the Water Treatment Plant. The WTP is rated at 4.0-MGD with a hydraulic capacity of 6.0-MGD. The plant contains two vacuum upflow Superpulsator clarifiers, four Greenleaf filters with supplemental air scour during filter backwash, SCADA and telemetry controls, Responsible for obtaining required permits, design of hydraulic conditions for raw water pumps, high service pumps, and transmission line. Coordinated building layout and site design.

Waste Water Treatment Plant Expansion (Town of Alexandria): The plant design consists of a Sequential Batch Reactor (SBR) system that contains two concrete treatment basins each 41-feet by 41-feet by 18-feet depth. The SBR basins contain influent piping, fixed course bubble diffusers with three 25 HP centrifugal blowers, floating decanters, volume/depth pressure transducers, and sludge pumps. The design also includes conversion of the existing steel treatment tank to a digester that includes a floating aerator, sludge pump, influent piping, and decants piping. The plant design contains a new suction lift pump station rated at 560 gpm at 65-feet TDH, static headworks screen, sludge dewatering box (gravity flow), post equalization lagoon (previously utilized as a post aeration lagoon), effluent control valve, ultraviolet disinfection system, effluent post aeration flume, influent and effluent samplers, influent and effluent flume/ultrasonic flow recorders, instrumentation/controls, and associated components. Under direction of Project Manager, I coordinated all drawings activities and details, making many design decisions regarding site layout, component connections, pipe sizes, and SBR controls. Extensive calculations to utilize post-equalization basin to control effluent release

State Hydraulic Calculations-Water Projects and Gravity Sewer Lines: Have prepared multiple (over 100) submissions for large and small water line projects, and gravity sewer lines. Utilizing various methods including hand calculations, WaterCAD computer modeling and spreadsheet applications. Calculations provided for minimum pressure, fire flow, and system capacity.

Water System Distribution Map and Modeling GIS Implementation (City of Spring Hill): Developed water distribution base map utilizing Microstation, compiled information from various sources, documenting every detail of system. Developed hydraulic computer model utilizing Haestad Methods WaterCAD to predict system behavior. Model consisted of over 600 nodes. Required field calibration and specific knowledge of all system components. Continue to update and utilize model to plan for system expansions and industrial activities. Specify GPS/ GIS equipment and secure funding for city implementation of GIS to include all city utilities, land-use/zoning activities and coordinate emergency response.

NPDES State Pretreatment Program -Complete program coordination: Responsible for entire pretreatment program for several municipal clients including: City of Fairview, Town of Hartsville, City of Erin, Metro Moore County/Lynchburg, City of Decherd Submission of Semi-annual reports, preparation of industrial user permits, monitoring and site inspection activities, Implementing and revisions to Enforcement Response Plan (ERP) and Sewer Use Ordinance (SUO).

Wastewater Treatment Plant Lift Station (City of Spring Hill): The project consists of a 15-foot by 15-foot by 32-foot wetwell, submersible pumps, controls, jib crane, emergency generator, approximately 26 feet of 18-inch ductile iron pipe, 26-feet of 30-inch ductile iron pipe and 375 feet of 8-inch PVC force main and appurtenances. The operating capacity of the lift station is 1500 GPM (2.16 MGD). Responsible for all drawings and details, including pipe layout, selection of jib-crane, calculations of wetwell volume and pump capacity.

Storm Water Collection and Detention System (City of Winchester): Designed large 2 acre detention pond with outlet controls to alleviate flooding along US 64 within a 110 acre drainage basin. Project consisted of installing dual 48-inch inlet pipes and 36-inch discharge piped to creek.
