CANWETTM (v 4.2) is a GIS-based software suite designed to inform decision making around river basin and watershed management; water supply and wastewater treatment infrastructure; food security; and, climate change adaptation. Its ability to quickly estimate daily water balance, nutrient, erosion sediment, and bacteria loadings from GIS input data allows CANWETTM to serve as a powerful decision support system.
This latest release of CANWETTM is VB.Net database-driven and web-aware, and features an integrated open source GIS environment. Its relative ease of use and ability to take advantage of commonly available spatial data makes it a solid choice over other continuous models with greater data input requirements. This "All-In-One" software suite allows you to begin your project without requiring expensive prerequisite software to use in tandem.
Since 2003, CANWETTM has been used for Assimilative Capacity Studies; Watershed and Sub-watershed Studies; Master Drainage Plans; Infrastructure Planning; and, Source Water Protection Studies. Various versions of the GWLF engine that is incorporated into CANWETTM have also been applied in numerous studies worldwide.

CANWETTM (v 4.2) offers an extensive range of features and useful tools including:
CANWETTM allows the user to quickly and easily generate input data through Geographic Information System (GIS) clipping routines. Data is clipped from GIS vector and grid maps. The clipping routines are used to generate input data for single or multiple basin analyses.
The Generalized Watershed Loading Function (GWLF) is a continuous model based on land use categories. It simulates stream flow, sediment, nutrient (nitrogen and phosphorous), and fecal coliform loadings from catchments, given variable-size source areas (i.e. agricultural, natural, and urban/developed lands).
CANWETTM allows for the addition of beneficial management practices (BMPs) by applying area-weighted loading rate reductions for phosphorous, nitrogen, sediment, and animal coliforms for both rural and urban lands. Multiple practices can be added in parallel or in series. It also calculates estimated costs for typical BMP applications based on unit-costing.
CANWETTM features several powerful output approaches to suit your needs.

I am writing to acknowledge the completion of a successful R&D project funded by the National Research Council’s Industrial Research Assistance Program (NRC-IRAP).
Your firm’s performance on the project was excellent, and your team was a pleasure to work with.
The CANWET product that you have commercialized since the end of the project represents a strong step forward in your field, and you should be proud.
We wish you well in the successful commercialization of the technology, and the continued growth of your firm which will contribute to the Canadian economy.

The reappearance of excessive nutrient loading in Lake Erie and the subsequent algae blooms is an extremely complex issue and is quite different in nature than the previous phosphorous loadings in the 1970s. Unlike the issue in the 1970s, there are far more sources adding nutrients to the late and these sources are diverse in nature ranging from rural to urban. In order to understand the nutrient loading, both in the temporal and spatial domains, more complex analytic and predictive tools are required in order to help policy make sound, science based, and defendable solutions.
The University of Guelph is uniquely positioned to help address the issues around Lake Erie with long standing core strengths in both the agricultural sector and the environmental field. In conjunction with our partner, Greenland Consulting Engineers, and their watershed evaluation tool (CANWETTM), we believe that we have the engineering and technology to extrapolate CANWETTM from the watershed level up to the lake basin level and provide decision-making support for the entire Lake Erie basin.

Town of The Blue Mountains
On behalf of the Town of The Blue Mountains, we would like to thank you and your organization for your specialized technical support in a peer review capacity over the past four years… Your team not only provided timely review of all drainage related features of development applications but introduced updated municipal design criteria addressing changing climatic conditions. By unraveling the weather factors that impact snow melt potential, your team has helped the Town better understand how to be proactive in developing sustainable infrastructure.
Your team’s support assisted in keeping Town’s development projects moving forward efficiently. In addition to this, the review and introduction of updated municipal design criteria and construction standards addressing changing climatic conditions, continues to ensure the Town of The Blue Mountains fulfills its mandate for sustainable development.
