dc.description.abstract | In developed countries the sanitation and treatment of urban wastewater is well sustained and technically solved by means of conventional pipe networksandsubsequentcentralizedtreatments.However,developingcountries lack these infrastructures and are in need of sustainable, decentralized and economically viable solutions for the disposal of their urban wastewaters. In addition to this, there are situations where the demands of conservation of naturalspacesdonotallowintensiveconstructiveproceduresandwhichforce the implementation of sanitary engineering with less environmental impact. We present the Ecological Wastewater Sewer (EWS), an ecological urban sewerage system that simultaneously transports wastewater and improves its quality.Thisinnovativetechnologyisanalternativetoconventionalsanitation piping that has minimal environmental impact. It is based on a successful previous work for the improvement of artificial wetlands in a pilot scheme andatfull-scaleonatestsite.TheEWSisachannel-shapeddevicethatrelies on the application of two key developments: a carefully designed cornered stones layout, and the creation of a natural aeration system. This way, it acts as a separating sewage system that guarantees the presence of a chamber of circulating air within the transportation unit, favouring permanent aerobic conditions in the upper levels of the mass of wastewater. Furthermore, its capacity to set tle suspended solids allows the EWS to be used as a sedimentor in water purification processes. A real-life application of this system proved successful in the sanitation of a district of Managua (Nicaragua). Working with a 100-metre-long street of 20 one-story houses, the system is reported to still be in full operating order after six years. The conclusions and results drawn from its monitoring are meticulously explained in our paper, as well astherecommendations&guidelinesforthedesignofmoreEWSunits,with aim to the popularization of this affordable, efficient and green approach to wastewater sanitation. | es |
