Förslag till reducering av framtida interna vattenflöden vid Svedala avloppsreningsverk genom ombyggnad av vassbäddar / Proposal on how to reduce future internal flows at Svedala wastewater treatment plant by repurposing reed beds

In 2004 Svedala wastewater treatment plant constructed ten reed beds. The beds had, however, to be taken out of commission after just a few years, due to complications. Eight beds now stand empty, while two are up and running for a limited trial period. The municipality is interested in the possibility of converting the remaining eight beds into detention basins to reduce internal flows and to reduce the risk of overflow occurring at the plant. The treatment process will suffer if the internal flow exceeds 400 m3/h. Exceeding volumes should be redirected to the detention basins. Three different suggestions on how to design the detention basins are given. All three proposals are based on current geometry of the reed beds. The final recommendation is that the reed beds should be converted into open detention basins. These basins have a high storage capacity and therefore also the best ability to reduce internal flows and reduce overflows at the treatment plant.
