Cartago Case Study: Waste Water Management in Rural Areas of Costa Rica

Abstract

This article provides information on the management of the grey and toilet water collected in rural areas of the province of Cartago, from the years 2014 to 2016. For this research, information was gathered from a survey applied to 614 households located in rural areas. Information was also obtained through field visits and a physical-chemical and microbiological analysis of surface and residual waters. It was found that 100% of greywater from houses in rural areas are thrown into their surrounding rivers and 87% of wastewaters are treated in septic tank systems. Pollution is observed in the surface water sources due to the increase of population density in rural areas and discharge without greywater treatment.
