Constructed wetland for the treatment of domestic wastewater as decentralised solution

In Bulgaria, almost all inhabitants are served by centralised drinking water supply but 98% of the villages donīt have any adequate wastewater collection or treatment. The unsafe sanitation and wastewater system sets public health at risk and pollutes groundwater and surface waters. Especially in rural areas, there is a lack of financial, technical and staff resources, thus low-tech, cost-efficient and sustainable wastewater management systems are needed.

Technical drawing vertical-flown subsurface constructed wetland (Otterwasser):

The goal of the project is to raise awareness and to build capacity among professionals as well as citizens about extensive wastewater treatment processes which are cost-effective and sustainable.
WECF in cooperation with Otterwasser, TUHH and Ecoworld carries out the following project steps:

  • Design, construction and start-up operation of a vertical-flown, subsurface constructed wetland as demonstration onsite wastewater treatment plant (80 PE) for the childrenīs home in Vidrare, Pravetz, Bulgaria
  • Development of an advisory technical leaflet about constructed wetlands for pro-fessionals in English and Bulgarian language
  • Training for professionals during the construction
  • Organisation of a national conference about constructed wetlands for wastewater treatment in Sofia
  • Awareness raising about the link between hygiene, wastewater treatment and envi-ronmental protection and about extensive wastewater treatment options. Target group are school children in Pravetz.
