Lagoons, low tech solutions
Lagoons (or waste stabilization ponds) and other low-tech systems (e.g., trickling filters) are solutions able to provide good wastewater treatment efficiencies with low investment costs.
IRIDRA proposes low-tech options when the local conditions are not suitable to install a constructed wetland treatment plant. An example is the design of WWTP for developing countries, when the minimazion of investment costs is of primary importance.
