Senior Technical Consultant, Marshalltown IA, Wastewater System Master Plan, 2010.Provide review of flow analysis for the Marshalltown Wastewater Master Plan. The project intent was to assess the capacity of the sanitary sewer system and identify the potential for inflow and infiltration (I/I) removal from the collection system. The City of Marshalltown, IA’s sanitary sewer system has experienced sanitary sewer overflows (SSOs) and basement backups during wet weather events. The system is comprised of approximately 760,000 linear feet of pipe, seven (7) pump stations, and 1 treatment facility, the Water Pollution Control Plant (WPCP). The Public Works/Engineering Department has initiated a plan to address the SSO occurrences and improve the capacity and operations of its sanitary sewer system. The City is working collaboratively with the Iowa Department of Natural Resources (IDNR) in enhancing the level of service for the sanitary sewer system.

Senior Technical Consultant, Trinity River Authority of Texas, Preliminary Design Report and Condition Assessment for the Elm Fork Interceptor, 2010. Provide review of assessment and preliminary design for the Elm Fork Interceptor Segments EF-R1 and EFR2. The Elm Fork interceptor system is one of five major subsystems conveying wastewater to the Trinity River Authority (TRA) Central Regional Wastewater System (CRWS) plant in Grand Prairie, Texas.The Preliminary Design Report focused on two older 72-inch lines which are 50 and 24 years old respectively. Based on the results from a cost/benefit analyses and hydraulic evaluation of nine rehabilitation and replacement alternatives, an alternative for design was selected for implementation.

Project Manager, Johnson County Wastewater (JCW) Nelson WWTP Complex Pilot I/I Design, 2011. Lead a CH2MHILL team and oversee three other consultant teams developing design documents for public and private sector rehabilitation in both the public and private sectors of the system. Public sector rehabilitation included manhole and public main sewers. Private lateral rehabilitation included removal of building sources of I/I and rehabilitation of private building laterals. The project included preparation of public outreach materials, letters of notification and public meetings. The project also included a review of asset data inspection protocols and initiated the steps toward leveraging inspection and design data into the overall JCW asset management process.

Project Manager, Johnson County Wastewaster (JCW) Nelson WWTP Complex Phase 2 PEFTF Analysis, 2011.As part of JCW normal planning process and also in response to an EPA 308(a) data request, work was completed in 2007-2008 to develop preliminary alternatives to handle the wet weather flows within the sanitary sewer service areas tributary to the Nelson Wastewater Treatment Plant (WWTP) complex. The two service areas include the Shawnee Mission Turkey Creek Watershed (SMTC) and the Mission Township Main Sewer District No. 1 Watershed (MTM1). The preliminary alternatives showed that two significant data gaps exist in the cost-effectiveness analysis conducted to determine the least cost solution that would meet the design criteria. These data gaps addressed as part of this project included, the types, flow rates, and removal effectiveness of infiltration/inflow sources that are overloading the system during wet weather; and determining the amount of small diameter sewers overloaded in the MTM1 system as only the trunk lines have been modeled to date. These small diameter sewers represent about 90% of the total sewer length in the MTM1 Watershed.
