Individual Sewers in Nordmalings Municipality – Evaluation of Factors when Prioritizing Inventory Areas and Demands of Individual Sewers

The purpose of this study was to examine what to consider when prioritising inventory areas for individual sewers, as well as how an inventory should be initiated in Nordmalings municipality. The information was gathered by studying legislation, documents by government agencies, maps and by conducting a questionnaire survey. The study showed that the demands on individual sewers must be separately determined in every individual case. Sewer system shall have further wastewater treatment than only septic tanks, for example an infiltration plant. The demands should be determined by the protection level of the Environmental Protection Agency's guidelines (NFS 2006:7) for small sewage systems for domestic wastewater. The areas demanding a high level of protection are sensitive to emissions from individual sewers. Such areas can for example be Natura 2000, bathing places and water that is sensitive to eutrophication. The questionnaire was sent to 85 property owners and 64 of them responded. The majority of the ones with permanent housing had septic tanks (90.5 %) and an infiltration plant (60.0 %). The questionnaire indicated that the majority of the individual sewers were acceptable but that a significant part may have serious flaws. Prioritisation of inventory areas can be based on the areas that need high level of protection. Based on these results, coastal areas in Nordmalings municipality should be prioritised for an inventory of individual sewers.
