Our New York City office is transforming – both in size and location – to better assist local clients with their water resources and wet weather management issues. From our new location at 1410 Broadway in Manhattan, we welcome Vincent Rubino, PE, and Ivana Nitzova, PE, who bring expertise in the design and construction of wastewater conveyance and treatment facilities as well as combined sewer overflow (CSO) projects. They are currently providing ongoing design assistance for the New York City Department of Environmental Protection’s (NYCDEP) Gowanus Canal CSO storage facilities project in Brooklyn, NY, along with other projects.

Vincent has built his 43-year career focusing on the water and wastewater fields. His experience encompasses extensive facility planning, design and construction management of various NYCDEP projects. Vincent has managed design and construction of wastewater facilities worth over $500 million as well as more than a dozen facility plans and odor studies for wastewater treatment plants and biosolids facilities. He is actively involved in the Program and Sustainability Committees of the New York Water Environment Association (NYWEA). He holds bachelor’s and master’s degrees in Chemical Engineering from Stevens Institute of Technology as well as an MBA from Fairleigh Dickinson University.

Ivana is a civil engineer with 7 years of design experience in wastewater treatment, conveyance, and disinfection systems. She has designed improvements for municipal wastewater treatment facilities throughout the State of New York as well as a large ozone disinfection project for the City of Montreal. Ivana holds bachelor’s and master’s degrees in Biological and Environmental Engineering from Cornell University and is a member of NYWEA.

The Western Westmoreland Municipal Authority (WWMA) is constructing major sewer system improvements to eliminate wastewater discharges into the Brush Creek during wet weather events, as per a Consent Order and Agreement (COA) with the Pennsylvania Department of Environmental Protection. To support implementation of the COA improvements project, Wade Trim developed a permanent flow monitoring program for the interceptor system and provided hydraulic model development, model calibration, alternative development, cost estimates and alternative evaluation. The preferred alternative advanced through design and permitting includes replacement of 7 miles of interceptor and construction of a 7-MG equalization basin near the Brush Creek Wastewater Treatment Plant (WWTP). A 45-MGD influent pump station is also required to pump wet weather flow into the equalization basin due to the local topography and geology.

The interceptor will be upsized from 8- to 33-inch-diameter to 12- to 48-inch-diameter pipe. Constructability was a major concern as the existing interceptor runs along Brush Creek and Bushy Run with major sections either in the toe of the stream bank or in the stream itself. The design also accommodates three miles of asbestos cement pipe (ACP); a parallel system will be used so that the existing ACP interceptor can be removed from service and left in place. The equalization basin is an above ground wire- and strand-wound, circular, prestressed concrete tank located on a hill adjacent to the WWTP. In addition, WWTP upgrades will be made to improve hydraulic performance and operations.

Due to the size and complexity of the project, construction is phased over four years. The equalization basin, pump station and WWTP improvements are currently under way with interceptor construction scheduled to begin this fall. The entire COA improvements project is required to be complete by May 2020.

Committed to optimizing its wastewater treatment capabilities, the City of Jackson, MI, added a new, circular primary clarifier to its wastewater treatment plant (WWTP) and is preparing to upgrade its disinfection system. Designed to treat a maximum flow of 18.8 million gallons per day (MGD), the WWTP includes two existing rectangular primary clarifiers dating to 1933 and 1959 and one circular primary clarifier from 1977. The new clarifier was designed to improve the WWTP’s reliability, efficiency and maintenance flexibility by allowing existing primary tanks 1-6 to be removed from service while still meeting 10 States Standards requirements.

Construction of the new clarifier required excavation 25 feet below grade into bedrock, below the water surface elevation of the nearby Grand River. Careful consideration was required during the structural design phase to address potential uplift due to high groundwater. Soil borings and exploratory excavation were available to bidders so existing conditions were clear. Determining the clarifier’s weir elevations was also a key design consideration to enable splitting the flow evenly between the new and existing circular tanks and to enhance operations. Wade Trim provided field survey, civil/site layout, process and structural design, permitting and cost estimate preparation, and bid and construction phase services for the new clarifier project.

Wade Trim has begun design of the WWTP’s upgrade to UV disinfection technology to eliminate the use of chemicals, benefitting staff safety and the environment. After evaluating potential UV systems and apparatus, Wade Trim recommended housing the UV process in an existing chlorine tank to avoid construction of new underground structures. Building Information Modeling (BIM) is being used to recommend modifications to the existing structure to accommodate narrow vertical spacing and challenging hydraulics requirements. Only three of the WWTP’s five chlorine contact channels are typically used, leaving two channels available to site the UV system with minimal impact on existing operations during construction. The UV disinfection upgrade is anticipated to be complete in 2018.

Advanced facilities planning optimized $2.1 billion worth of the Northeast Ohio Regional Sewer District’s combined sewer overflow (CSO) control projects, which are required to capture and treat 98% of combined sewage flows in the Cleveland area and reduce CSOs to Lake Erie by 90%, compared to baseline levels, by 2035. Wade Trim led a team of consultants in advancing planning concepts for 5 deep storage tunnel systems and collection system improvements in 3 sewer districts to a 20% preliminary design level. This improved approach to streamline CSO program implementation reduced costs by approximately $350 million, or 16%, as well as potential risks and neighborhood disruption. The project was honored by the American Council of Engineering Companies of Ohio with a 2017 Outstanding Achievement Award.

The rock and soft ground tunnels span 19 miles to control CSOs for 81 square miles of heavily urbanized combined sewer service area. The scope and cost of proposed facilities were reduced by optimizing use of the existing interceptor system; adjusting routing to minimize disruption; minimizing construction of deep open-cut infrastructure; confirming project interrelationships, basis of designs, schedules, and costs; and identifying real estate required for critical structures. Modifications were supported by extensive sewer system flow modeling. Seven collection system models were updated and converted to InfoWorks ICM and 3D water quality, Computational Fluid Dynamics, and hydraulic transients surge modeling were performed.

The CSO Advanced Facilities Plan has set the stage for cost-effective program delivery by helping to avoid technical conflicts, schedule delays, cost increases and unacceptable risks when design and construction services are procured for proposed projects. With one of the nation’s highest levels of CSO control, NEORSD’s CSO program will help protect Lake Erie as a key freshwater resource. Projected savings are being used to help member communities implement sanitary sewer improvements that will also improve regional water quality and public health by controlling sanitary sewer overflows and basement flooding.
