This project aims to provide sustainable long-term solutions in Hidalgo County, Texas in areas of large minority populations of moderate to low-income households, by surveying failing or absent Decentralized Onsite Wastewater Treatment Facilities (OWTF). A community outreach and bilingual education campaign will be carried out to educate rural and Colonia homeowners on the importance of and best management practices for properly maintaining OWTF to eliminate the discharge of untreated sewage into the Rio Grande River watershed. A direct impact of this project will be improving resident’s knowledge on the environmental health impacts of improperly maintained septic tanks.
