Abstract [en]

The purpose of this study was to improve the knowledge about stormwater and water coolant at an industry, and in this case, Volvo GTO Umeå. It investigates which benchmark that should be used, Volvo GTO Umea’s pollutant load over a year and how the industry should sample the outgoing stormwater and water coolant. Article researches and interviews with the municipality and operations was the method for the sampling plan. Article researches were also used to find suitable benchmarks. To calculate the pollutant load, data were gathered from books, Internet and verbal sources. The conclusion is that it is hard to establish a flow proportional sampling plan for Volvo GTO Umeå when only a few companies uses the method and when it does not exist any national guidelines. It takes a lot of time to calculate a stormwater pollutant load on the recipient if the area has more than one sampling stormwater drain that has an outflow to the recipient. If the runoff coefficient is the same for all the sampling storm drains and standard concentrations is used as pollutant data, the pollutant load can be misleading for each sampling storm drains. It is important for a company to have benchmarks to compare their sampling data with. The benchmarks should consider the recipients sensitivity, to prevent impact on it.
