Framework
Wastewater production in tourism units located in rural areas undergoes through high oscillations in terms of effluent quality and quantity, due to variations in guest occupation along the year, negatively affecting the performance of conventional treatment systems. The costs of implementation and operation of conventional systems for hotels or small communities is prohibitive in many situations, mainly in rural and mountain areas where there are no systems for collecting and processing waste water.
The use of Constructed Wetlands as main functional unit, for example in domestic wastewater treatment, or as a complementary treatment system, enables possibilities for water reuse.
