Bolivia's Water Sources: An Exploration Of Supply And Access

Bolivia, a landlocked country in South America, has faced a water crisis in recent years, with water shortages affecting hundreds of thousands of people. The country's water sources include aquifers, glaciers, and rainfall, but these sources are under threat from factors such as drought, climate change, and mining activities. Bolivia's government has implemented measures to improve water access and sanitation, with varying degrees of success, and the country continues to work towards ensuring clean water for all its citizens.

Water committees and community education

Bolivia's drinking water and sanitation coverage has improved since 1990, but the country still has the lowest coverage levels on the continent and the quality of services is generally poor. In 2015, 90% of the total population had access to "improved" water, with higher access in urban areas (97%) than in rural areas (76%).

In rural areas, "Juntas" or Water Committees are responsible for operating and maintaining the water systems. Water For People, an organisation that implements piped water supply systems in Bolivia, has helped districts create water and sanitation offices (called DMSBs) that support communities with the operation, maintenance, and oversight of water services.

Water For People also promotes a market-based approach to sanitation, encouraging families to invest in their own household toilets that meet their preferences and needs. They support microfinance for sanitation improvements, so families can access small loans to build better bathrooms, and ensure that sanitation products are locally available.

In 2009, the Bolivian Constitution officially declared access to drinking water and sanitation a human right. The Bolivian people formed "water committees" to spread information about the management of water resources, sanitation, and environmental challenges.

Water committees are crucial for community education and empowerment. They play a vital role in raising awareness about water-related issues, promoting sustainable water management practices, and advocating for the right to water for all. By involving local communities in decision-making processes, water committees foster a sense of ownership and responsibility for water resources.

These committees also play a vital role in addressing the unique challenges faced by rural communities in Bolivia. For example, in the district of Villa Rivero, a program to cover the cost of 10-20% of a family's bathroom has led to more families building bathrooms. This not only improves sanitation but also empowers families to take control of their health and well-being.

Additionally, water committees can facilitate community engagement and participation in water management. For instance, in the city of Cochabamba, citizens took to the streets during the Cochabamba Water War in 1999 to protest the privatisation of the city's water. As a result, the government reversed the privatisation and returned water management to public hands. This demonstrates the power of community mobilisation and the important role that water committees can play in advocating for the rights and needs of their communities.

Furthermore, water committees can also play a role in monitoring and addressing water contamination issues. For example, in the city of Potosí, countless truckloads of public water were being sold to mining firms, which likely contributed to water scarcity and impacted the availability of safe water for the community. Water committees, with their local knowledge and engagement, are well-positioned to identify and address such issues promptly.

In conclusion, water committees are essential for community education and empowerment in Bolivia. By involving local communities in decision-making, raising awareness about water-related issues, and advocating for the right to water, water committees play a vital role in ensuring access to safe drinking water and sanitation for all Bolivians.

Water rationing

Bolivia's water sources include glacial supplies, rivers, and aquifers. However, the country has faced significant water shortages and rationing in recent years, particularly during the worst drought in 25 years in 2016.

The water crisis has affected over 100 neighbourhoods and approximately 400,000 people in La Paz and the neighbouring city of El Alto. Water is being distributed by trucks, with residents allowed to fill only two containers at a time. The La Paz Medical Association has advised treating the water with bleach before consumption due to concerns over the previous use of the trucks for carrying fuel.

The Bolivian government has responded to the crisis by declaring a national state of emergency, tightening water rationing, and proposing infrastructure projects to address the issue. President Evo Morales also dismissed top water officials and formed a group of technicians to devise solutions for the water shortage. Plans include installing 300 metres of piping to pump water from the nearby Kairuni River, but this is expected to meet only a quarter of the city's needs.

The water shortage in Bolivia has been attributed to various factors, including melting glaciers, mining activities, government planning, and climate change. The country's glaciers have receded by over 40% since 1985, reducing the water supply, especially during dry months. Additionally, mining activities have accelerated the depletion of rivers and water sources.

Water Sources in Bolivia

Bolivia's water sources are diverse and vary across the country. In certain regions, such as La Paz, El Alto, and Viacha, the population depends on water from aquifers, such as the Purapurani aquifer, for their water supply. This aquifer is crucial for everyday use, urban expansion, and sustaining agriculture.

Bolivia has also utilised nuclear technology to study and manage its water resources. Isotopic techniques have been employed to gather information about the age, quality, and source of groundwater, helping to plan its use more effectively.

Despite the improvements in water coverage since the 1990s, Bolivia still faces challenges in providing consistent and high-quality water services to its population, particularly in rural areas. The country is working towards strengthening citizen participation in the sector and increasing investment to address these issues.

Water sources and contamination

Bolivia's drinking water comes from a variety of sources, including surface water from lakes, rivers, and streams, as well as groundwater from aquifers. The country has been facing a deepening water crisis due to various factors, including shrinking glaciers, extreme droughts, and management challenges.

One of the main sources of water in Bolivia is the Purapurani aquifer, which supplies water to the cities of El Alto and Viacha near the capital, La Paz. This aquifer covers an area of 300 km² and supports a population of over a million people. However, a study using nuclear technology revealed that the water in the northern area of the aquifer is contaminated, possibly due to mixing with river water.

Bolivia also relies on glacial supplies for its water, especially during dry months. However, the glaciers in Bolivia have been receding at an alarming rate, with a loss of over 40% of their ice cover since 1985. This has led to a reduction in the quantity and quality of water available, as glaciers are a significant source of freshwater.

The country has also faced challenges with privatization and regulation of its water supply. In 1999, during the second mandate of Hugo Banzer, the sectoral institutional framework law (Law 2029) was established, allowing for private sector participation in water and sanitation services. This led to two major concessions being granted to private companies in Cochabamba and La Paz/El Alto. However, these concessions were met with widespread protests and were ultimately terminated in 2000 and 2006, respectively, with water management returning to public hands.

Despite these challenges, Bolivia has made significant improvements in drinking water and sanitation coverage since 1990 due to increased sectoral investment. In 2015, 90% of the total population had access to "improved" water, with higher access in urban areas (97%) compared to rural areas (76%). However, the quality of service in most water and sanitation systems is still low, with proper disinfection and wastewater treatment lacking in many cases.

To address the ongoing water crisis, the Bolivian government has implemented various measures, including declaring a national state of emergency during the 2016 drought, tightening water rationing, and allocating funds towards securing access to clean water and improving sanitation systems. Additionally, projects like the Water Evaluation and Planning (WEAP) tool have been developed to help the country plan for future water security and improve water conditions nationwide.

Government planning and investment

The Bolivian government has made efforts to improve water planning and build capacity in the regions to enhance their understanding of water availability, current water usage, and potential future developments. This includes the utilisation of nuclear technology to uncover the secrets of the Purapurani aquifer, which supplies water to the cities of El Alto and Viacha. Isotopic techniques have been crucial in gathering information about the age, quality, and source of the groundwater, enabling better planning for its use.

Bolivia's Ministry of Environment and Water has played a pivotal role in addressing the country's water challenges. They engaged with SEI to develop a "national water balance" using the Water Evaluation and Planning (WEAP) system. This comprehensive model incorporates data from field measurements and satellite records to provide a detailed understanding of Bolivia's water supply. The Ministry and SEI also organised training and discussion sessions to ensure that planners could effectively utilise the tools and data available to them.

The Bolivian government has also demonstrated its commitment to improving water access by allocating significant financial resources. Under President Evo Morales, almost $3 million has been dedicated over 13 years to secure access to clean water, sanitation, and irrigation systems. This investment has contributed to the country's progress towards its goal of providing clean water access to its entire population by 2025. As of 2017, around 86% of the population had access to safe drinking water, and more than 95% of city residents could obtain clean water.

Additionally, the government has set ambitious goals to achieve universal access to drinking water services by 2020 and sanitation services by 2025. To realise these goals, they have implemented piped water supply systems and established water and sanitation offices (DMSBs) to support communities in operating, maintaining, and overseeing water services. The government has also promoted a market-based approach to sanitation, encouraging families to invest in household toilets that meet their specific needs.

However, challenges remain, particularly in rural areas. As of 2017, more than three million people in these regions lacked access to clean water, leading to gastrointestinal illnesses. Droughts and environmental threats further compound the issue, underscoring the importance of continued government planning and investment in water security for all Bolivians.

Climate change and shrinking water sources

Bolivia's water sources are under threat from climate change, with the country facing a deepening water crisis. The effects of climate change, such as shrinking glaciers and extreme droughts, are already being felt in Bolivia, and the country is struggling to secure alternative water supplies. The capital city of La Paz and the neighbouring city of El Alto, in particular, have been facing water shortages due to the impact of climate change on their water sources.

La Paz is the highest capital city in the world, and both it and El Alto rely heavily on water from the glaciers in the surrounding Andean mountains. However, these glaciers are now shrinking rapidly due to rising temperatures. Between 1983 and 2006, the two Tuni-Condoriri glaciers that provide water for El Alto and La Paz lost 39% of their area, and one glacier on Chacaltaya mountain has already completely disappeared. As a result, the three main dams that supply water to the two cities have nearly run dry, leading to water rationing and protests from residents.

The effects of climate change are also being felt more broadly across Bolivia, with the country suffering from frequent droughts and water conflicts. In 2016, Bolivia experienced its worst drought in 25 years, affecting 125,000 families and 283,000 hectares of agriculture and leading to a state of emergency being declared. This was followed by another historic drought in La Paz in 2017. The situation is made worse by the fact that Bolivia cannot easily rely on new sources of water due to the costs and potential range of climate change impacts.

The Bolivian government has been criticised for its handling of the water crisis, with protesters arguing that the government has failed to take measures to secure alternative water supplies. However, the government claims that the protests are being used to foment opposition to President Evo Morales' rule. Nonetheless, the government has taken some steps to address the water crisis, including declaring a state of emergency, tightening water rationing, and drawing up infrastructure projects.

To build resilience to climate change, Bolivia will need to implement conservation and recycling methods and find ways to reduce water consumption. The country is also working to improve water planning and build capacity in the regions to better understand their water availability, current water uses, and potential future developments. This includes the development of a "national water balance" dataset to inform water planning and the creation of a comprehensive model of Bolivia's water sources using advanced computational methods.
