Project Goals

  • Implementation of three pilot Green Filter systems in Colombia (innovative constructed wetlands) in order to improve sanitation and hygiene situation
  • Immediate improvement of the living conditions of poorer population groups in the three pilot communities (Cuítiva, Fúquene, Susa) in rural areas of Colombia


Background

Lake Fúquene (3,260 ha) is a shallow lake with a great endemic biodiversity. It provides water supply for 200,000 people, cattle and agriculture, and sustains fishing and rush extraction activities. Loss of water capacity, exotic fish introduction, eutrophication, contamination, and aquatic macrophytes infestations are its principal threats. Currently there is no protection status.

 

Lake Tota is the largest of Colombia’s lakes; it holds 2,000 million cubic meters of water, providing water to nearly 500,000 people in the region. The lake was designated an Important Bird Area (IBA) site in 2008, and has had 116 bird species recorded since 2003, 7 of them endemic, and some endangered or at risk of extinction at an international level. The flow of untreated wastewater represents a potential threat to the ecological integrity of the wetland.

 Susa: Pipiline from the village to the green filter
 Susa: Excavation and construction of the desander, sifting and inlet sampling well
 Susa: Channel excavation
 April 2015: The green filter in Susa is nearly finish.
