One Page Summary

• At the moment untreated sewage/waste water from the inhabited islands is polluting Danube Delta.
• By implementing Constructed Wetlands that treat the sewage, no untreated waste water/sewage is being discharged in Danube anymore.
• For the Constructed Wetland is a small area needed, a few square meters.
The construction can be done by local contractors with local available materials
Constructed Wetlands are very beneficial, eco friendly and high efficient.
A Constructed wetland consists of a sand filter with infiltration tubes and effluent tubes. A small low energy pump (solar panel) brings the sedimentated water over the sand filter. In the sand filter many bacteria and micro-organisms treat the waste water.
The efficiency of the system is very high. The treated water that comes out of the filter through the drainage, effluent pipes is so clean, you cannot see the difference between tap water when compared. In the Netherlands constructed wetland are applied in the most vulnerable areas.
• Wetlantec builds constructed wetlands for over 24 years in the Netherlands, Belgium, GB, Germany, Brazil, Ukraine, Turkey, Canada and Bangladesh.
• In the Netherlands the constructed wetland is the most efficient decentralized waste water/sewage treatment available. Wetlantec already build more than 2400 constructed wetlands for water boards, municipalities, resorts, campsides, visitor centers at nature parks etc.
• Constructed Wetlands can be applied almost anywhere
• The strength of constructed wetland is there is almost none malfunction because the system is very robust
• The weakness of constructed wetlands is that they need a small area, approximately 1,5 m2 / person. So where no land is available it’s not possible to implement one.
