The below-ground treatment plant will


improve the quality of local water sources and ensure they meet Water Framework Directive requirements


Czech town welcomes wastewater treatment installation


A new wastewater treatment system installed in a town in the Czech Republic will protect valued fishing ponds and raise the quality to required EU environmental standards. Packaged wastewater treatment plant providerWPLinstalled a below-ground system in Klimkovice, in the country’sMoravian- Silesian region, as part of a municipality-led project to construct a first-time sewerage network to serve 340 of the town’s residents. Some110 properties will connect to thenew system, replacing ageing septic tanks that had been seeping into streams which flowed into the popular fishing ponds, impacting the quality of the waters, which have protections under the EU’sWater Framework Directive.The projectwaswelcomedby the local community and its successful completion marked with an opening ceremony. Frantisek Lindovsky,WPL’smanager for central Europe, said:“Itwas the municipality’s aim to protect the ponds and provide a clean and healthy environment for the fish, which iswhy the decision was taken to invest in anew sewer network and sewage treatment plant. WPL’s technology was considered the most suitable because our treatment units are modular, compact and ready-to-use. “The completed system, which will be fed by the town’snewsewer network, will significantly improve the quality of the local streams and fishing ponds and ensure they meet the environmental standards set out by

To manage this, engineers built a temporarywell so that water could be continuallypumpedout and levels kept down throughout construction. The installed treatment plant –WPL’sHybrid- SAF biological system– comprises units designed to control chemical oxygen

demand (COD), biochemical oxygen demand (BOD) suspended solids, and ammonia.A remote monitoring systemwas also installed. The high environmental standards required included 30mg/lBOD, 110mg/lCOD, 40mg/ l suspended solids and 20mg/l ammonia. To protect the below-ground units from excess groundwater the excavation was fully backfilled with water-resistant concrete. A small biological pond was also constructed by a municipality-sourced supplier to provide
