Backflow Uncovered: In this project, the Basement Flooding Area is at high risk of basement flooding due to inadequate conveyance capacity, with constraints linked to either the local sanitary sewers or the trunk sewer system. A Ramp-Up Analysis was conducted to determine the source of the capacity limitation within the network. The results indicated that the trunk sewer was experiencing bottleneck surcharging, leading to backwater effects that adversely impacted the local sewer system.

Holding the In-Line: Major capacity constraints were identified, leading to the prioritization and assessment of mitigation strategies to improve the City’s network performance. The selected solution features In-Line Storage via a 900mm diameter Superpipe, along with a 250mm diameter flow regulator installed at the downstream end of the proposed sewer. This enhancement ensures sufficient capacity and maintains freeboard in the downstream network by limiting flows to pre-development conditions.

When Sewers Meet Streets: In this project, a state-of-the-art coupled 1D-2D simulation method is employed to evaluate urban flooding. Coupled 1D-2D simulation integrates one-dimensional sewer network modeling with two-dimensional surface flow modeling to provide a comprehensive assessment of urban flooding. This approach captures the dynamic interaction between underground drainage systems and overland flow, enabling accurate prediction of flood extents and depths in complex urban environments.

Trust Begins with Calibration: In this project, available flow monitoring data was used to adjust the parameters of the InfoWorks model to closely reflect real-world conditions. A stepwise calibration approach was employed, beginning with Dry Weather Flow (DWF) calibration, followed by Wet Weather Flow (WWF) calibration. The results demonstrate that the calibrated model is reliable and suitable for strategic planning and design of the municipal network.

Below Grade, Above Expectations: In this project, stormwater management for the proposed public road is addressed by utilizing oversized pipes that provide detention and regulate discharge flows to protect the adjacent creek. Additionally, ponding areas are delineated based on a detailed hydraulic analysis using HEC-RAS to ensure there is no adverse impact on neighboring private properties.
