Senior Hydraulic Modeller
Requisition ID: 23955
Located on the traditional, ancestral and unceded lands of the Musqueam, Squamish, and Tsleil-Waututh, Vancouver has a commitment to becoming a City of Reconciliation. Vancouver consistently ranks as one of the world’s most liveable cities and is working towards being the greenest city in the world. Named among Canada’s Top 100 Employers, BC’s Top Employers, and Canada’s Greenest Employers, the City of Vancouver seeks colleagues who can help shape and embody our core commitments to sustainability, decolonization, equity and outstanding quality of life for all residents.
Consider joining our committed team of staff and being part of an innovative, inclusive and rewarding workplace.
Main Purpose and Function
Responsible for undertaking modelling analysis in support of development of a Sewage and Rainwater Management Plan (“SRMP”) for Vancouver. The SRMP will form a comprehensive long-range plan to address pollution arising from combined sewer overflow events and urban runoff, along with adapting to climate change, population growth and aging infrastructure. It will help to strategically target billions of dollars in investments in the decades to come.
The SRMP is being developed in close coordination with Metro Vancouver, and much of the modelling work in support of the plan will be utilizing Metro Vancouver’s MIKE URBAN model of major infrastructure components of the Vancouver Sewerage Area (“VSA”), along with discrete models to be developed by the City for representative watersheds within Vancouver. Given this high level of collaboration and use of Metro Vancouver’s VSA model, this position will be working closely with Metro Vancouver staff and will be dedicating a significant portion of time working out of Metro Vancouver’s office (either in-person or virtually). This person will also facilitate information sharing and collaboration between City and Metro Vancouver staff to support coordinated planning across both organization’s collection systems. This position will also be working closely with colleagues within the Integrated Strategy and Utilities Planning division of the City of Vancouver’s Engineering Department.
Specific Duties and Responsibilities
- Participate as a key team member in SRMP planning activities including workshops to define strategic objectives, risk analysis, baseline forecasts, scenario development, pathways evaluation and final adaptive plan development
- Understand the VSA system as represented within the Mike Urban VSA model (i.e. assumptions, criteria, boundary conditions, calibration levels and corresponding levels of confidence etc.)
- Work with MV to identify areas of the VSA system at the trunk level that are under-utilized and those that are overtaxed during storm events, and help to establish a common understanding of system performance between the City and Metro Vancouver
- Understand the contribution of different urban drainage areas and their compounding impact on CSOs, SSOs and capacity issues across the system
- Use the VSA model outputs, monitoring and field data to estimate contaminant loadings to the receiving environment associated with model runs
- Use the VSA model outputs and the SRMP urban watershed analysis (i.e. issues and opportunities) to prioritize watersheds for implementing source controls that will alleviate greater system bottlenecks and mitigate sewer overflows
- Develop and run scenarios as part of the SRMP development process.
- Develop discrete models of representative Vancouver watersheds using InfoWorks ICM to evaluate the effectiveness of different infrastructure and policy tools
- Assist in delivery of technical reports related to the hydraulic modelling tasks including preparation of graphs, sketches and figures and hydraulic plans & profiles
- Recommend potential monitoring locations and data inputs required for additional model calibration and validation
- Undertake other forms of engineering planning analysis
- Engaging with staff from Metro Vancouver, City of Vancouver, and the City of Vancouver’s consultant as needed to undertake analysis and facilitate shared learning as part of the SRMP development process
- Act as a conduit for information flow and coordination between CoV and MV staff to support strong collaboration between the two organizations in the development of the SRMP..
- Assist MV efforts to investigate challenges and uncertainties in system understanding discovered during regular use and calibration of the Regional model. This is anticipated to include coordination between CoV and MV operations and utility planning staff.
- Manage the work of and support junior staff as required
- Other duties/responsibilities as assigned
Education and Experience:
- Bachelor’s degree in Engineering, and considerable related sewers system modelling and planning experience.
- Graduate degree in a related field is considered an asset.
- Registration or eligibility to register as a Professional Engineer in BC
- Hydraulic and hydrologic modeling experience specifically related to combined sewer, sanitary and drainage networks
- Proficiency in hydraulic modelling procedures including: model build, sewage load allocation, model calibration, scenario development, and system assessment
- In depth knowledge of sewer infrastructure planning principles including flow and rainfall monitoring, growth and population projection, inflow & infiltration, system evaluation, and capital projects
- Proficiency in Mike Urban and familiarity with a variety of hydraulic and hydrologic modeling software such as InfoWorks ICM and PCSWMM
- Experience in urban sewer flow, rainfall, and I&I analysis
- Working knowledge of ESRI ArcGIS Pro and relevant data sets tools and analytics
- Valid BC Driver’s license an asset
Knowledge, Skills and Abilities:
- Ability to work collaboratively and with different partners and stakeholders
- Understanding of the operation and performance of combined sewer, sanitary and drainage infrastructure
- Knowledge of the regional sewer and drainage system, Liquid Waste Management Plan, and related municipal responsibilities is considered an asset
- Strong interpersonal and writing skills (ie. technical reports, presentations, letters & memos)
- Ability to analyze and exercise independent judgement to make recommendations and facilitate decisions
- Ability to multi-task, while still progressing a project
- Ability to work independently with little supervision
