Planificación Hídrica de la Cuenca Tupiza

The report provides a comprehensive strategic and programmatic framework for the Tupiza River Basin, focusing on improving water security, sanitation, and climate resilience. It identifies critical vulnerabilities, including mining-related water contamination, inadequate sanitation in rural areas, and high susceptibility to floods and frosts. The plan proposes specific infrastructure investments—such as rainwater harvesting tanks, deep wells, and decentralized wastewater treatment plants—alongside gender-focused empowerment programs and sustainable mining management to mitigate environmental degradation.

• The Tupiza River Basin covers approximately 2,309 km² and is characterized by a semi-arid climate where evapotranspiration represents 76% of precipitation, indicating low water regulation.
• Mining activity is a primary economic driver but a major environmental threat; 684 Mining Environmental Liabilities (PAM) were identified, with approximately 95% having received no management.
• There is a stark disparity in sanitation access: while 94.5% of urban households in Tupiza have improved sanitation, 57% of rural households practice open defecation.
• Water collection in rural areas is a gendered burden, with women responsible for collection in 40% of rural households compared to 23% for men.
• The basin is highly vulnerable to hydroclimatic risks; a 2018 flood destroyed the wastewater treatment plant's emissary and damaged the facultative lagoons, leading to the discharge of untreated sewage into the Tupiza River.
• The plan prioritizes three micro-basins for urgent intervention: Palala-Tambillo, Cabecera del río Salo, and Río Tatasi, focusing on biodiversity protection and erosion reversal.
• Proposed water infrastructure includes rainwater harvesting tanks for dispersed populations (investment of 1,472,040 Bs) and deep wells with conventional networks for larger communities (investment of 18,045,618 Bs).
• The plan proposes a decentralized wastewater treatment system for concentrated rural communities, including a bioreactor and horizontal biofilter, with a total investment of 26,753,228 Bs.
• To improve agricultural productivity, the plan identifies five priority irrigation projects requiring a total investment of 63,175,599.59 Bs, including the Salo dam and irrigation system.
