Nature sanctuary El Peral lagoon, is located in El Tabo, San Antonio, Valparaiso, Chile, is a wetland surrounded by urbanization, it has 25 hectares of protected land (approximately 16 correspond to the wetland), it was declared a sanctuary in 1975, and CONAF (national forest corporation) took over its administration in 1983. The wetland is an important migration point for birds that come from the northern hemisphere, which travel looking for nesting and feeding areas, so if the wetland disappears, the number of migratory birds will be reduced, because they should travel more distances to arrive to a new migration point. The wetland is seasonal, it is dries some seasons in the year, due to climate change and low rainfalls in the past years. The creation of a new sewerage network will allow water in the area to increase, it will also clean the water and pour it back into the wetland, helping to recover the water level of the wetland, restoring the flora and fauna of the place, avoiding prolonged droughts. In addition, the sewage treatment plant would allow irrigate cultivation areas, both of orchards, and nurse-ponds characteristic of the wetland. Sludges that are obtained from water treatment would serve as fertilizers, and the water cycle could be used entirely. The use of the sanctuary as a recreational and environmental education place, will integrate into the urban area, as a public space, that encourages care of the ecosystem and allow people to bond with it.
