A tool to support upstream work - Development

Purpose and goal

A map-based tool for substance flow analysis of pollutants in the wastewater network has been developed. The tool calculates amounts of pollutants from user defined areas, as well as summarized input to a wastewater treatment plant. The overarching purpose is tracing and quantifying sources of polluting substances in the catchment areas of wastewater treatment plants, in order to facilitate well adapted measures. A first functional version of the tool is now available for the cities Landskrona and Malmö. Functionality will improve with time as further data are entered into the tool.

Expected results and effects

The tool facilitates calculations needed for the wastewater utilities reporting to environmental authorities and the certification organization Revaq. The tool will be marketed by Gemit Solutions AB as SourceAnalytics, complementary to the tool Envomap which is used by several Swedish wastewater utilities. Expectations are that further utilities will be using the tool, which will contribute to standardization of methods for upstream work.

Planned approach and implementation

The project has been executed in co-operation between the wastewater utilities NSVA and VA SYD (problem owners and users of the tool), RISE Research Institutes of Sweden (development of the cal-culation model), and Gemit Solutions AB (software development). A very competent reference group has been associated to the project. A planning project, where the layout and functionality of the tool was described in detail, has contributed strongly to successful execution of the development project.
