Mexico has invested in water sanitation projects for the Tijuana River

Mexico has been taking steps to address its water crisis and reduce water pollution. In terms of the Tijuana River specifically, Mexico has invested in water sanitation projects, recognising the critical importance of addressing water pollution for the benefit of its citizens and those in bordering countries.

Mexico highlighted a $46 million investment by local, state, and federal authorities in water sanitation projects for the Tijuana River between 2019 and 2021. This investment is part of a joint effort with the U.S. to reduce transboundary flows of polluted water in the Tijuana River, which is a priority for both countries. The U.S. has also committed to a $300 million investment by the EPA to reduce transboundary wastewater flows in the river and along the Pacific Coast. This comprehensive plan will deliver reliable wastewater treatment for over 500,000 Tijuana residents and benefit the ecosystems and communities of both countries.

Mexico has also developed a new regional plan with the Federal Government and the State of Baja California to address transboundary pollution flows. The Mexican delegation presented a draft "Special Northern Border Sanitation Program" to seek additional resources for future projects, including wastewater collection and reuse projects in Tijuana.

In July 2022, Mexico and the U.S. signed two binational agreements, the Statement of Intent and Minute 328, committing to reduce transboundary wastewater in the Tijuana River watershed and the Pacific Ocean through infrastructure projects. These agreements outline $330 million in funding from the U.S. and $144 million from Mexico for sanitation projects in San Diego and Tijuana.

The EPA has also announced two near-term clean water projects in the Tijuana River, including increasing treatment of river flows by 10 million gallons per day through diversion to the IBWC International Treatment Plant. The second project will address sediment and trash in Smuggler's Gulch, just north of the U.S.-Mexico border, to reduce pollution and flooding risks. These projects are funded through the EPA's Border Water Infrastructure Program.

The country has committed to reducing transboundary flows of polluted water

Mexico has demonstrated its commitment to reducing transboundary flows of polluted water through participation in the U.S.-Mexico Binational Meeting on Transborder Water Pollution. During the meeting, Mexico highlighted its significant investments in water sanitation projects, totalling $46 million from local, state, and federal authorities between 2019 and 2021. These investments specifically targeted the Tijuana River, recognising the importance of reducing pollution levels for the benefit of both U.S. and Mexican communities.

The Mexican delegation also presented a new regional plan, developed jointly with the State of Baja California, to address transboundary pollution flows. This plan underscores Mexico's dedication to finding a lasting solution to transboundary pollution issues. As part of this plan, CONAGUA, the National Water Commission, reaffirmed its commitment to funding wastewater treatment, collection, and reuse projects in Tijuana.

Additionally, Mexico introduced a draft "Special Northern Border Sanitation Program," which aims to secure additional resources for future projects. This demonstrates Mexico's proactive approach to addressing transboundary water pollution. The U.S. and Mexican delegations agreed to enhance coordination on projects and funding sources related to wastewater collection and reuse, as well as the rehabilitation of wastewater treatment plants to effectively manage wastewater from coastal communities.

The two countries also acknowledged the priority of reducing transboundary flows of polluted water in the Tijuana River, canyons, and coast. They pledged to continue joint efforts and emphasised the forthcoming $300 million investment by the EPA, which will significantly reduce transboundary wastewater flows in the Tijuana River and along the Pacific coast. This comprehensive plan will not only benefit residents and tourists in the region but also positively impact ecosystems on both sides of the border.

Mexico is working with microfinance institutions to empower them with the technical skills and training they need to launch their own financial products for water and sanitation solutions

Mexico is facing a water crisis, with 57% of its population lacking access to safe water and 37% lacking access to safe toilets. The country has made significant progress in recent decades, with increased access to piped water supply and improved sanitation in both urban and rural areas. However, a lack of investment has slowed progress in providing safe water to low-income communities. Mexico is also grappling with water scarcity, droughts, inadequate drinking water quality, and inefficient wastewater treatment.

To address these challenges, Mexico is working with microfinance institutions to empower them with the technical skills and training they need to offer financial products for water and sanitation solutions. This approach is being implemented by Water.org, which is collaborating with associations of microfinance institutions and credit cooperative institutions. By providing these financial institutions with the necessary tools and knowledge, they can create their own financial products tailored to water and sanitation solutions, such as WaterCredit.

The impact of this initiative is already being felt, with Water.org's first partners disbursing loans for water and sanitation solutions in early 2020. This has enabled families to access affordable and sustainable safe water solutions, such as water storage cisterns. Water.org is committed to expanding its partnerships with financial institutions, non-governmental organizations, local governments, and infrastructure partners to accelerate its impact in Mexico.

Microfinance institutions play a crucial role in providing small loans to families, helping them overcome the financial barriers associated with high upfront costs of connecting to piped water supply or building latrines. By focusing on water and sanitation solutions, these institutions contribute to addressing the world's pressing human development challenges. This approach has been successfully implemented in other Latin American countries, such as Guatemala, where microfinance institutions have shown a willingness to explore non-traditional financing initiatives, including those related to water and sanitation.

The government has installed rainwater harvesting systems and water purification technologies

Mexico has been facing a water crisis, with 57% of its population lacking access to a reliable, safely managed water source. In addition, the country has been dealing with issues of water scarcity, droughts, inadequate drinking water quality, and wastewater treatment. To address these challenges, the Mexican government, in collaboration with organizations like Isla Urbana, has taken several measures, including the installation of rainwater harvesting systems and the implementation of water purification technologies.

Rainwater harvesting has been a crucial strategy in Mexico's efforts to combat water scarcity and provide sustainable water solutions. Isla Urbana, a prominent organization in this field, has led large-scale rainwater harvesting initiatives across the country. Their projects focus on developing advanced rainwater harvesting technologies and empowering local communities through training in installation, maintenance, and repair. By promoting shared rainwater systems and enhancing water management practices, Isla Urbana has helped families in water-scarce areas meet their essential water needs.

One notable example of rainwater harvesting success is the San Gregorio Xochimilco project. This initiative provided thirsty families in Acapulco and the surrounding areas with user-friendly rainwater harvesting and purification technologies. Additionally, Isla Urbana expanded its efforts to cities like Guadalajara, Guanajuato, and Monterrey, collaborating with government and private partners to supply low-income communities with rainwater harvesting systems.

In addition to rainwater harvesting, the Mexican government has also focused on implementing water purification technologies to improve water quality. One innovative approach is the use of solar power to purify water, as demonstrated in the remote village of La Mancalona. MIT researchers developed a photovoltaic-powered reverse osmosis (PVRO) system, utilizing solar panels to convert sunlight into electricity and power pumps for the filtration process. This system purifies both brackish well water and collected rainwater, providing the village with about 1,000 liters of purified water daily.

The success of the La Mancalona project has spurred interest in replicating similar solar-powered water purification systems in other communities. MIT's experience has highlighted the adaptability and affordability of the technology, making it suitable for various environments, including jungle villages and crowded cities. By empowering communities with the skills to operate and maintain these systems, Mexico is taking significant steps toward ensuring access to clean and affordable water for its citizens.

Mexico has upgraded its systems to deal with the growing volume of garbage

Mexico has been taking steps to address its water pollution crisis, which has been exacerbated by factors such as rapid urban growth, industrial pollution, and climate change. One significant measure undertaken by the country is the upgrade of its systems to manage the increasing volume of garbage effectively.

Mexico City, in particular, has been grappling with severe water pollution issues. The city has invested in hardware upgrades, modernizing its pipes to cope with the growing amount of waste. This includes initiatives such as changing and improving pipes to handle the volume of garbage. This hardware investment is a crucial step in the right direction, as acknowledged by Cámara, a local diver who has witnessed the city's water issues firsthand.

However, despite these improvements, there are still fundamental challenges to be addressed. One critical issue is the lack of a culture of recycling and proper waste segregation among the Mexican populace. According to Cámara, the country's poor education and lack of awareness about waste management contribute to the water pollution crisis. This cultural aspect needs to change to achieve long-term, sustainable progress in reducing water pollution.

To address transboundary water pollution, Mexico has been actively collaborating with the United States. During the U.S.-Mexico Binational Meeting on Transborder Water Pollution, both countries reaffirmed their commitment to reducing pollution levels in shared water bodies. Mexico highlighted its investment of $46 million in water sanitation projects for the Tijuana River between 2019 and 2021. Additionally, the U.S. and Mexico agreed to coordinate on projects related to wastewater collection and reuse, with a focus on the Arturo Herrera and la Morita Wastewater Treatment Plants, and the rehabilitation of the San Antonio de los Buenos Wastewater Treatment Plant.

Furthermore, Mexico City has been implementing rainwater harvesting systems to reduce its dependence on groundwater sources. The 'Aqua a tu Casa' program, launched in 2016, aims to address drinking water scarcity in marginalized areas. By installing rainwater harvesting systems and water purification technologies, the city has saved 75 million liters of water, benefiting 56,320 people. These systems not only conserve water but also ensure its quality, eliminating 99% of pathogenic bacteria and mitigating waterborne diseases.
