Dvigi: Ultrafiltration Technology for a Healthier and More Sustainable Future

Carolina Pittella – Project Manager at Agua Segura

When it comes to water projects in rural areas, the challenge isn’t so much about the “what” but the “how.” In my experience, understanding the community and the local water resources is the first and most critical step to developing an effective action plan. Listening to people, learning about their customs and needs allows us to create realistic, sustainable projects that truly make a difference in their lives.

I always start by involving local teams as key partners in the process. They are the first to point out the limitations and challenges we’ll need to tackle. Although it can seem overwhelming at first, this is when the right questions emerge, and the true scope of the project begins to take shape. These teams have an unmatched understanding of the local climate, the best times to work, the local suppliers, and the logistics—like road conditions and costs—that can make or break a project. Paying attention to these factors can significantly improve the project’s success and optimize resources.

Along with local teams, foundations that have been working in the area for years are invaluable partners. Not only do they understand the community’s specific needs, but they also help facilitate initial contacts and adjust the project’s scope when necessary. Building strong relationships with these foundations opens doors to faster and more efficient solutions. Entering a community with a trusted local partner by your side makes it easier to navigate future challenges.

Another crucial element in planning is choosing the right communication channel for each team. Not everyone communicates or processes information the same way. Figuring out whether a call, video call, message, or email is the best option helps keep the workflow efficient and effective. It’s also important to adjust communication frequency based on everyone’s availability, and when needed, to make in-person visits to strengthen relationships and ensure the project stays on track.

Ultimately, a project in a rural community will only succeed if we truly understand the local context and build strong partnerships with those who know the area best. In this way, teamwork becomes the key to bringing safe water to those who need it most.

In Mexico, like many other countries, the agricultural sector is the main consumer of water. According to INEGI data, it accounts for over 67% of the total volume used nationwide. This figure highlights the urgency of implementing sustainable water management strategies, especially in a context of growing water crisis.

The country’s water security is closely linked to the agricultural sector’s ability to adapt and make more efficient use of the resource. Especially small-scale agriculture, which occupies about 72% of Mexico’s agricultural territory, still heavily relies on gravity irrigation systems, also known as furrow or flood irrigation. These systems have an estimated efficiency between 20% and 40%, leading to significant water loss, often groundwater, which could be better utilized.

Optimizing Irrigation is Possible: Experience from the Field

At Regenera Bajío, we work with producers to improve irrigation practices and move towards effective water conservation. We have proven in the field that, with adequate technical advice and commitment from the producer, efficiencies of up to 80% can be achieved. This translates into less water extraction, reduced costs, prevention of agricultural diseases, and, in many cases, improved productive yields.

But beyond tools and technologies, the key to change lies in the human factor. The experience, knowledge of the territory, and willingness of producers are fundamental to achieving a transition towards more sustainable agriculture.

A People-Centered Methodology

Aware of the particularities of the Mexican countryside, we developed an intervention approach centered on the producers. Our team provides personalized technical advice, with field visits that allow us to analyze the specific conditions of each plot: soil type, slope, crops, availability of irrigation infrastructure, and access to water.

Through interviews and direct observation, we analyze current practices:

• How do they irrigate?
• When and how often?
• Why is that system chosen?

With this information and data measured on the ground, we propose practical and accessible adjustments, such as modifications to irrigation scheduling, valve installation, or small leveling works. These changes, adapted to the producer’s reality, usually have an immediate and significant impact on water use efficiency.

Changing Deep-Rooted Habits: A Cultural Challenge

One of the most relevant challenges is modifying habits that have been passed down from generation to generation. Many producers repeat irrigation routines because “that’s how it’s always been done,” even if they are not always the most suitable for the current climatic and environmental reality.

Therefore, our approach prioritizes close accompaniment, establishing relationships of trust from the beginning of the process. Listening to their doubts, responding with technical evidence, and respecting their timelines are key to generating lasting transformations.

We also promote the active participation of producers in recording field data. This exercise allows them to observe for themselves the results of the implemented improvements, which reinforces evidence-based decision-making and empowers communities to care for their resources.

Reusing Knowledge: A Virtuous Cycle

Another essential aspect of the methodology is returning the information generated in each agricultural cycle to the producers. This not only improves water management in their productive units but also strengthens the collective memory of the territory.

Furthermore, water efficiency becomes a gateway to other key issues, such as aquifer recharge, water quality, or even the relationship between agriculture and the restoration of aquatic ecosystems. Water that is not wasted in the field is water that can be kept in rivers, wetlands, or natural reservoirs.

Training, Community, and Local Solutions

Training is a transformative tool. Therefore, we organize group workshops in the communities where we work, addressing topics such as:

• Current water challenges in Mexico.
• Rights and obligations of producers.
• Tools for measuring soil moisture.
• Alternative irrigation systems and their maintenance.
• Successful cases of transition to sustainable agriculture.

These spaces not only generate knowledge but also strengthen community ties and foster the exchange of solutions that arise from the territory.

Beyond Water: Towards Regenerative Agriculture

Improving irrigation efficiency is just the first step. At Regenera Bajío, we seek to generate a systemic impact, where water security is articulated with climate resilience, rural well-being, and the agroecological transformation of the Mexican Bajío

This implies moving towards productive systems that:

• Contribute to aquifer recharge.
• Prevent the contamination of water bodies.
• Strengthen community water projects.
• Integrate into watershed management.
• Respect natural water cycles.

Conclusion: Alliances for the Future of Water

In the face of the water crisis, we need concrete, scalable, and just solutions. Irrigation efficiency is not just a technical goal: it is a key strategy to ensure water today and tomorrow. But to achieve it, technology is not enough. It requires knowledge, accompaniment, and, above all, trust in the transformative capacity of the producers.

At Regenera Bajío, we continue to bet on this path: one that unites knowledge, promotes collective learning, and cares for water as the common good it is.

When we think about the importance of water for our lives and development, we surely imagine the rivers, seas, and lakes that feed us, provide energy, and recreation. If we go a bit further, perhaps we reflect on the importance of wetlands and ecosystems that work to mitigate the effects of climate change. But there is a place where practically all the planet’s liquid fresh water is concentrated: beneath the earth.

Groundwater has enormous significance for human society. Its sustainable management and protection are essential to guarantee water security, food production, drinking water supply, and the health of ecosystems.

Groundwater: the invisible resource that sustains life

Access to safe water is a fundamental human right. We only need to remember the “water cycle” we learned in school to understand that what we do on the surface directly affects what happens beneath it. If the water circulation process is interrupted, terrestrial ecosystems lose their balance, and with them, aquifers deteriorate.

According to UNESCO data, over 95% of the world’s available liquid freshwater is groundwater, and it is estimated that 50% of the world’s population depends on it for domestic consumption.

These natural reservoirs supply not only our homes but also sanitation systems, industries, and, above all, the agricultural sector.

Agriculture and Aquifers: A Critical Relationship

Agriculture is the largest consumer of freshwater on the planet. According to the FAO, about 40% of the water used for irrigation globally comes from aquifers. And it is estimated that to feed a global population of 9 billion by 2050, food production must increase by 60%.

However, the excessive use of groundwater for irrigation can lead to its depletion, reduced river flow, and loss of wetlands. Furthermore, if they become contaminated with agrochemicals, fertilizers, or other substances, their quality is jeopardized, and negative impacts on public health are generated.

Sustainable water management in agriculture is crucial. Adopting efficient irrigation technologies, improving soil infiltration, and reducing chemical use are key steps to protect this invisible resource.

Groundwater Conservation and Recharge of Aquifers

Aquifer recharge is the natural process by which rainwater or river water slowly penetrates the soil and reaches underground layers. But when areas are deforested, soils are compacted, or urbanization occurs without planning, this process is interrupted.

At Agua Segura, we promote nature-based solutions that allow us to recover this natural absorption capacity: soil restoration, reforestation of watersheds, wetland conservation, and rainwater harvesting systems.

These actions are part of integrated watershed management strategies aimed at strengthening the water resilience of territories.

Groundwater and Climate Change

Groundwater plays an important role in mitigating climate change. By maintaining stable river levels, they sustain ecosystems during droughts. They also prevent saltwater intrusion in coastal areas, protecting freshwater reserves against rising sea levels.

However, the water crisis has exacerbated aridity in regions where the only source of supply is groundwater. There, sustainable management is not an option; it is a vital necessity.

Water Quality: A Silent Challenge

In addition to depletion, groundwater contamination is a serious challenge. Chemical substances such as nitrates, pesticides, heavy metals, or hydrocarbons can slowly infiltrate and remain for years, affecting water quality without being detected.

Implementing monitoring systems, improving land use planning, and promoting corporate water responsibility are necessary measures to prevent this deterioration.

Making the Invisible Visible

Groundwater knows no borders. Therefore, its preservation requires a global, collaborative, and long-term perspective. According to UN Water, we need public policies, investments, and citizen participation to face emerging challenges.

We also need education and communication. Because making the invisible visible means teaching that what happens beneath our feet sustains everything that happens on the surface. And that without groundwater, there is no agriculture, no industry, no health.

The Basis of All Sustainable Development

Groundwater is a hidden treasure that we must care for, monitor, and manage responsibly. They not only guarantee access to water and sanitation (WASH), but they are also the basis of any sustainable development strategy that aspires to be just, resilient, and lasting.

Conclusion

We are facing a key resource for life. Invisible for decades, it now demands to be at the center of policies, investments, and collective consciousness.

Making the invisible visible is recognizing the infinite value of our groundwater. And acting accordingly.
