Hydraulic Modeling – R2T, Inc.

Our Experts

Computational Modeling can solve hydraulic and water quality equations for complex conveyance networks rapidly and accurately. Hydraulic models are powerful tools that engineers can use to investigate current system conditions, simulate future improvements, develop operational changes, and create capital improvement plans with optimal sequencing. R2T’s modeling team boasts a wealth of experience in hydraulic modeling. Beyond just the basics of capacity analysis, R2T can assist you in analyzing every aspect of a collection or distribution system. From targeting sewer inflows to SSO reduction to customer demand forecasts and distribution emergency management, we will leverage emerging technology to advance every aspect of your infrastructure.

Hartsfield-Jackson Atlanta International Airport Master Plan and Hydraulic Modeling Support

R2T assisted the City of Atlanta DWM with the development and implementation of a sewer system hydraulic model and subsequent condition assessment with wastewater monitoring and master planning services for critical infrastructure at Hartsfield-Jackson. We conducted a vulnerability assessment and managed internal inspection of a key pipeline and wastewater characterization through a sampling plan to identify waste load quality issues. R2T assisted the DWM’s Flow Monitoring Division in the implementation of a sewer metering program in a challenging, limited-access environment, and in ensuing data quality reviews. R2T’s expertise was key in managing the development of a hydraulic sanitary sewer model in InfoWorks ICM.

Bolton and Phillip Lee Pump Stations

R2T provided full-service, multi-discipline engineering design services to the City of Atlanta DWM for the replacement of the Bolton Road and Phillip Lee Pump Stations. R2T provided architectural, structural, process mechanical, civil, electrical, and instrumentation design services for two discreet design-bid-build packages, one for each station. As the lead firm, R2T also implemented hydraulic similitude modeling in conjunction with the Clemson Hydraulics Laboratory. Results of the models were used to optimize footprint and recognize cost savings while allowing adequate capacity to meet future flow projections.

East Park Reservoir Design & Engineering Services

R2T provided design and engineering services for process yard piping associated with the Philadelphia Water Department’s East Park Reservoir, a state-of-the-art 60-million-gallon storage facility designed for the hydraulic grade line of the upstream transmission system and the downstream service zone. Two 30 MG circular, pre-stressed concrete water storage tanks, supporting infrastructure, control structures, and monitoring structures were provided.

City of Atlanta Water Supply Program

R2T is the engineer of record for the pumping systems component of the City of Atlanta Water Supply Program. R2T led assessment and design efforts associated with four large pump stations associated with the program. Multiple innovative hydraulic designs and configurations were utilized to accommodate program needs at significant savings in cost and reduction in construction schedule by maximizing the value of equipment and mobilization and eliminating many obligations of the initial phasing plan.

Atlanta BeltLine Stormwater Design Services

R2T, as a subconsultant, has integrated Geographic Information System (GIS) with PC SWMM stormwater management software to develop hydrology and hydraulics analysis for the Northeast and Southside corridor design of the Atlanta BeltLine. The Southside and Northside Trail projects consist of the design of a 14-foot wide concrete multi-use path with 3-foot soft shoulders on each side extending approximately 4 miles. Our tasks included trail concept refinement and preliminary and final design.

Areas of Expertise

Water Distribution

Simulations of hydraulic and water quality behavior within pressurized pipe networks, consisting of pipes, junctions, pumps, valves, storage tanks, and reservoirs, can be used to track the flow of water in each pipe, system pressures and tank levels, chemical constituents, water age, and source tracing throughout the network. R2T has built, calibrated, and implemented some of the largest and most complex piping in the country, and we stand ready to assist you with your network.

Wastewater Collection

Collecting and conveying wastewater flow to a treatment plant in a reliable, economic, and compliant way is a challenging risk management exercise. R2T can model your system to help you understand your network’s choke points, identify problems, and choose the best course of action by leveraging tools that deliver proven excellence in hydraulic system analysis and design.

Stormwater Management Modeling

R2T has built a body of experience designing stormwater features in challenging environments that unite green infrastructure with pedestrian traffic and the constraints of aesthetics in the modern built environment. We use the Stormwater Management Model (SWMM) to fast-track hydraulic calculations and find ways for our clients to thread a needle and maintain compliance with stormwater regulations while minimizing financial investment and saving space for human uses.

Plant hydraulics

Treatment plant modeling can assist with problematic telemetry readings, a lack of definitive piping inventory, and flow distribution that does not match design. R2T’s modeling team has experience compiling SCADA data and field measurements to compare hydraulic simulations of what “should be” to what “is,” tracking down limitations to plant hydraulic capacity driven by subsurface infrastructure that outdates most plant operation staff.
