The simplest hydraulic modelling platform built on the trusted EPA SWMM engine.
Product Vision
VO SWMM is a cloud-connected hydraulic modelling platform that builds upon the proven EPA SWMM computational engine by combining intuitive engineering workflows, integrated hydrologic and hydraulic modelling, GIS, terrain analysis, collaboration, and decision-support tools. Its purpose is to help engineers, municipalities, and regulators design, evaluate, and manage resilient drainage systems with greater efficiency and confidence.
Background
Hydraulic modelling has traditionally required engineers to work across multiple software applications, datasets, and engineering workflows. While the EPA SWMM engine has become an industry standard for stormwater and sanitary sewer analysis, building, reviewing, and maintaining complex hydraulic models often remains time-consuming and difficult to manage.
VO SWMM was developed to simplify these workflows by combining the proven EPA SWMM computational engine with the intuitive interface, GIS capabilities, and engineering philosophy established by Visual OTTHYMO. The result is a practical hydraulic modelling environment that reduces model development effort while maintaining the flexibility and analytical capability expected by practicing engineers.
The Opportunity
Modern drainage systems require engineers to evaluate both surface and subsurface drainage as integrated systems while responding to increasing demands associated with urban growth, aging infrastructure, regulatory requirements, and climate resilience.
By combining hydraulic modelling, GIS, terrain analysis, hydrologic integration, project management, and engineering tools within a single platform, VO SWMM provides a more connected workflow for analysing, designing, and managing stormwater and sanitary drainage systems.
Product Direction
VO SWMM continues to evolve as an integrated hydraulic engineering platform capable of bringing together:
- Storm and sanitary sewer network modelling
- Integrated dual-drainage analysis
- Manhole inflow and infiltration (I/I) assessment
- Surface flow and flood mapping
- GIS and terrain-based model development
- Hydraulic design verification and sewer network profiling
- Stormwater infrastructure planning and capacity assessment
- Hydrologic model conversion from VO OTTHYMO
- Project management and scenario comparison
- Model quality assurance and data validation
- Collaboration and future cloud-based engineering workflows
The platform is designed to simplify hydraulic modelling while extending the capabilities of the EPA SWMM engine through practical engineering tools that improve productivity, visualization, and decision-making. The current platform already emphasizes integrated dual-drainage modelling, manhole I/I risk assessment, flood mapping, QA/QC, hydraulic design verification, and seamless OTTHYMO integration as defining capabilities.
Long-term Objective
The long-term objective of VO SWMM is to provide a unified hydraulic engineering platform that enables engineers, municipalities, watershed organizations, and regulators to understand drainage system behaviour, evaluate hydraulic performance, identify capacity constraints, assess design alternatives, and support better planning, operation, and infrastructure investment decisions.
As the platform evolves, VO SWMM will continue to expand the integration of hydraulic modelling, hydrologic analysis, collaboration, and engineering decision-support into a connected environment that simplifies complex drainage workflows while maintaining the reliability of the EPA SWMM computational engine.
