Valuable knowledge continues to be generated through the programmes facilitated by Partners for Water (PfW). Learnings and insights that can potentially benefit anyone working within the water security. That’s why sharing these is an essential part of what PfW does. This is where Bram van der Wielen comes in. As Knowledge & Communication Advisor he connects water enthusiasts around the world. Nice to meet you, Bram!

‘I’ve been with Partners for Water for about a year now’, Bram tells us. ‘Before coming here, I developed my communication skills at different governmental organisations, such as the Netherlands Nutrition Centre (Voedingscentrum), the Inspectorate of Education (Onderwijsinspectie) and the Dutch Flood Protection Programme (HWBP). The goal was always the same: to tell stories in a simple yet effective way.’

Bram used to feel that his job satisfaction mainly came from this and that the subject itself was less important. ‘However, when I started working for HWBP, this belief started to change and I became fascinated by the work of the Dutch water sector. So, when I saw the Knowledge & Communication Advisor vacancy at PfW, I was immediately sold. I love contributing to something we sometimes take for granted in the Netherlands: water security.’

Building traction

Within the PfW-programme, there are countless interesting stories to be told. But what is the best way to do this? ‘To help figure this out, I’m working with everyone who is involved with Partners for Water, which is a lot of fun. The past year we’ve taken important steps in improving PfW communications. We’ve increased our online presence and participated in more events. In 2024 we’ll keep building traction with a new website, corporate videos and inspiring content.’

‘Of course, expanding the Partners for Water network is also a big part of what we’re about. That’s why we’re constantly working on getting the right people to meet each other. Events play a big role in this. In 2024 there will be conferences on water tech and water management in Singapore and Indonesia, which we’ll attend. We’re also organising our own event, called Waterproof.’

Aiming for commitment

One of the goals with the events we’re involved in, is to get concrete and to try to agree on action right there at the event itself. We want to do more than just shake hands; we want change. That’s why we actively seek commitment on topics like Nature-based Solutions (NBS), biodiversity and social inclusion. An example of this is the Coalition on Nature-based Solutions launched at the United Nations Conference on Water in New York in March 2023. It is a powerful alliance to create a breakthrough in the implementation of NBS for water-related challenges.’

“Colombia’s current challenges in water and climate demand innovative solutions.” It’s an endeavour that many water professionals attending the Colombia Platform meeting on Thursday, 7 December are eagerly undertaking.

Over 45 individuals from public and private organisations, knowledge institutions and NGOs gathered in The Hague to discuss the bilateral collaboration between the Netherlands and Colombia, forge new connections and discover the various business opportunities the Colombian water and climate sector has to offer.

“I’m so pleased to see you all here today,” began Barbara Swart, Delta coordinator from the Ministry of Infrastructure & Water Management, as she initiated the meeting. “Together, we’ll discuss the ongoing collaboration between Colombia and the Netherlands, share valuable insights on successful practices and explore new market opportunities within Colombia’s water and climate sector.”

Bilateral collaboration

The delta collaboration between the Netherlands and Colombia has been facilitated through various instruments of the Dutch government, such as Water as Leverage (WaL), BlueDeal and Partners for Water (PfW). Key components in these cooperations include promoting local ownership, co-creating with stakeholders and collaborations with the local public and private sectors. The ‘Water as Leverage Cartagena – Construyendo con el agua’ programme illustrates this aptly. PfW Programme Advisor Robert Proos enthusiastically explains: “WaL Cartagena aims to develop sustainable, integral solutions for water adaptation and climate adaptation in Cartagena. This is carried out by two multidisciplinary teams and in partnership with local and international stakeholders. WaL Cartagena can also be an interesting launching pad for other water security innovations, so it’s a worthwhile exploration for the Dutch water sector.”

Blue Deal Programme in Colombia

“We aim to enhance the implementation power of solutions that improve water security in Colombia,” explained Ellen Bollen-Weide from the Dutch Water Authorities while introducing InspirAgua Colombia, a component of the Blue Deal Programme. This initiative, a collaborative effort by the Dutch Water Authorities, the Ministry of Foreign Affairs and the Ministry of Water and Infrastructure of the Netherlands, strives to provide access to sufficient, clean and safe water for 20 million people globally.

Partners for Water subsidy scheme

Another initiative enhancing water security in Colombia is the ASR4WS project, co-funded by Partners for Water. Marta Faneca Sànchez, a hydrogeologist at Deltares, enthusiastically elaborated on the feasibility study her team conducted on six banana plantations in Colombia’s Magdalena Delta. “During the dry season, the local rivers experience freshwater scarcity, which leads to the salinization of groundwater and soil, loss of biodiversity and conflicts among water users. With Aquifer Storage and Recovery (ASR) technology, we aim to address these challenges by storing fresh water during the rainy season that can be utilized during the dry period,” she explained.

Sànchez noted that the Partners for Water subsidy supported the project not only by providing funds but also by establishing vital connections with local stakeholders and partners, and it has been crucial for the project’s continuation. “The study reveals promising potential for adapting an existing well into an ASR system. To validate these findings, a pilot project will be conducted on one of the farms, with continued financial support from Partners for Water.”

Obtain funding through the Partners for Water subsidy scheme

Do you want to know if your project is also eligible for the Partners for Water subsidy scheme? Projects with innovations in the field of WASH, water quality & availability, water & climate, water & biodiversity, sustainable agriculture and water infrastructure can apply for the subsidy from 19 January until 16 February 2024.

Market opportunities

“Colombia is taking big steps towards treating 100% of its wastewater and providing drinking water to an additional 3 million Colombians by 2030,” said Wessel Mol from the bilateral chamber ‘Holland House Colombia’. Speaking from his office in Bogotá, Mol shared his excitement about the numerous opportunities for the B2B market across various regions in Colombia. The most significant ones are highlighted below:

Significant opportunities in various Colombian cities:

• Cartagena: improvement of drinking water and sewerage coverage in rural areas, equipment needs for the new treatment plant El Cerro, IT tools for storage and distribution of water.
• Santa Marta: drinking water and sewerage coverage, and rainwater capture.
• Bogotá: wastewater treatment
• Cúcuta, Neiva and Duitama: wastewater treatment systems

A promising water and climate sector

As this fruitful meeting ended, Swart concluded with a hopeful summary: “Today we’ve recognized that working at the regional level is just as important as collaborating at the institutional level, and I believe we can all agree there are numerous opportunities within Colombia’s water and climate sector. The current challenges require innovative solutions, and I am confident that you have the products and expertise necessary to enhance water security in this promising delta country.”

We previously featured an article on the activities of Partners for Water in Colombia. In the city of Cartagena, two multidisciplinary teams are working to improve the city’s water system as part of the ‘Water as Leverage Cartagena – Construyendo con el agua’ programme.

Both teams design strategies and project proposals related to water and climate change challenges. We catch up with Programme Advisor Robert Proos to give an update on the status of the programme.

Since February 2023, the teams have been working on 11 proposals for inclusive, innovative and comprehensive designs to adapt the city to climate change impacts. They do this together with the city of Cartagena, the Colombian government and other stakeholders, including community representatives, the private sector and local academia.

An important focus of the programme is identifying and developing projects which are feasible and impactful. ‘What we notice is that there is often plenty of internationally funds available for the implementation phase of projects’, Robert explains. ‘However, a lot of interesting projects never reach that stage. That is why we want to close the gap between identifying promising projects and matching the available funds for implementation. In order to achieve this, we work together with financial partners such as Invest International and the European Investment Bank.’

Tested method

‘The programme aims to integrate local knowledge and experiences in designing solutions for the city’s challenges’, Robert explains. ‘That means it’s important to involve local communities. By connecting to their contexts, we are enabling inclusion and co-creation.’ This method has been tested and developed in Water as Leverage Asia, in the cities of Semarang (Indonesia), Khulna (Bangladesh) and Chennai (India). Robert adds: ‘The idea is to look beyond technical features. How will the solutions be socially embedded? How can we involve local communities, the private sector and NGO’s?’

Local Design Workshop 3 (September 2023)

Water as Leverage Cartagena

‘We learn about risks, ecosystem vulnerability and the needs of local communities from workshops. By listening and interacting, communities give important information as to how to move forward and at the same time we create broader support for the programme and the proposed projects. By introducing topics like policy and finance, we connect to policy ambitions of local governments and get them talking to potential financiers at an early stage.’

Real differences

Robert feels the integrated approach leads to more results than just siloed, single-focused solutions. ‘The right type of investments in water infrastructure can trigger so much more than just dry feet; integrated projects can improve the livelihoods of the ‘cartageneros’. For example, in addition to improving water management around the Ciènaga de la Vírgen wetland in Cartagena, the communities also see a potential for eco-tourism, supporting their livelihoods in a sustainable way. This type of integration uses water as leverage for the broader development of a city.’

The eleven proposals will soon be further developed and analysed to determine if they’re feasible from a technical, social, environmental and financial standpoint. ‘So, these great projects actually get implemented and the people of Cartagena start to notice real improvements.’

There are two teams working on improving the city’s water system. Why two teams and not one?

‘Of course, we could have gone for one big team with twice the budget’, Robert says. ‘However, what we noticed in other programmes and want to encourage, is that teams learn and get inspired by one another. Doing so creates synergies and new ideas.’

‘Because the teams are structured slightly differently in terms of who is in it, they work from different perspectives and ideas. Having two teams in this way enriches the process as a whole. and allows for greater collaboration with various local as well as Dutch partners. This is a good thing, as there is a lot of interest from the international water and climate sector to work on this programme.’

Southern Africa is suffering from severe drought. Together with Hydrologic and Emanti, research & consulting company FutureWater is working on an operational service that provides timely and easy access to water availability and demand across the entire Maputo River and the Black Umbeluzi River basins.

In our ‘Innovations in Progress series’, FutureWater’s water resources engineer Evelyn Aparicio Medrano tells us more about the underlying models for the GLOW project and the great power of collaboration

‘In the GLOW pilot project, we clearly show where the demand for water in the region is greater than the supply, from day-to-day to seasonal trends. On this basis, the local authorities in Mozambique, Eswatini and South Africa can make quicker and easier decisions about water management and water security in the short and the longer term.’ explains Evelyn.

One decision support system

Within the GLOW consortium, the FutureWater team – which, along with Evelyn, consists of hydrologists Tijmen Schultz and Sergio Contreras – is responsible for the models behind the forecasts. Evelyn: ‘Our role is to bring all the pieces of information together: the weather forecast, the size of the catchments, but also the availability of and demand for water at different locations in the delta. In order to do this, we use tried and tested tools. We bring all the collected data together in one decision support platform called HydroNet. This platform provides all stakeholders with an overview of the data, presenting actionable information through a dashboard. The coherent combination of the different technologies is one of the features that makes this project innovative and unique.’

The decision-makers can also run different scenarios. Evelyn: ‘GLOW is and will continue to be a forecasting service, so you always have to deal with the uncertainties in your models. This is why we offer the possibility to run several scenarios. These scenario’s predict different outcomes based on the available data and possible decisions. It enables water managers to make more considered choices for the short term and longer term by providing them a comprehensive understanding of the possible consequences of their decisions.’

Evelyn Aparicio Medrano

Across borders

Another feature that makes the GLOW project unique is that the river basin from the pilot crosses three borders. Evelyn: ‘Collecting information in Mozambique, Eswatini and South Africa and bringing it all together gives us a much clearer overview. Water managers from the three countries work together to share information and make decisions that are primarily in the interest of the entire catchment – and not just for their own area. We make this transparent and clear via GLOW, so that all parties involved can use the right information. All the stakeholders have access to the data from the other countries. It’s one system. I think that makes it a beautiful and innovative approach.’

User-centred

Users are at the heart of the GLOW project. Evelyn: ‘We only started modelling after the first discussions with the different authorities in the three countries involved. Our South African partner in the GLOW consortium Emanti has all the expertise and tools required in order to bring to light this basic information. We can of course come up with 10,000 wonderful things to model and show them in our dashboard, but ultimately the question is: how does our technology help local decision-making or discussions about water management and water security? Which data do our stakeholders need in order to make decisions? We seek continuous input from the stakeholders. This is very important for the further development of the dashboard, and it’s how stakeholders themselves become ambassadors for the system.

The challenges

There are also challenges in this pilot phase. Evelyn: ‘For our models we would really like to work with data series with around 20 consecutive years, but they’re very hard to find. With a bit of luck, you have a few years of data here and there. We need to collect all this data and analyse it, in order to be able to use it. But the biggest challenge is bringing the stakeholders together. For example, we had organised a kick-off for all three countries simultaneously. But in the end, we had to settle with a separate kick-off in each country. Now we’re also working hard on inviting all the stakeholders for the Renko Conference in November, where we will demonstrate the GLOW-dashboard and its capabilities.

Further roll-out

Evelyn is positive about the further roll-out of the GLOW project: ‘We’ve already gained a lot of experience as a consortium. FutureWater had already worked with both Hydrologic and Emanti on other water projects. We know each other’s unique expertise and what the other party can contribute to a project. Now we’re working hard to ensure that data can be exchanged even more effectively and that our system can communicate with other platforms. We also have an increasingly better idea of what information the different stakeholders need.

What does the future hold for international water innovation? Last week, over 20,000 water professionals gained insights into the promising answers to this question at Aquatech 2023 in Amsterdam.

Many visited the NL Lounge, which was hosted by Partners for Water (PfW) and was part of the NL Pavilion. One thing is clear: the future of water innovation looks very exciting.

Kick-off

Enthusiasm was in the air when Marieke Leenhouts from Netherlands Water Partnership (NWP) inaugurated the NL Pavilion at Aquatech 2023 on Monday 6 November. Together with NWP and Water Alliance, Partners for Water co-hosted the NL Pavilion and facilitated the NL Lounge. Over 23 exhibitors were ready to showcase their innovative water technologies and solutions in the inviting Dutch area amidst the vast international expo.  “Today is the start of a promising week,” Leenhouts said, “The programme is packed with inspiring talks, engaging network lunches and valuable delegation visits, without forgetting the free drinks during Wednesday’s networking event in the NL Lounge.” The stage has been set; let the unveiling of water innovation begin.

The overall Innovation Award was received by REDStack BV, who were recognised in the categories ‘Wastewater Treatment’ and ‘Innovation Not To Market’ for their Blue Energy Technology. With membrane stacks they generate renewable energy out of contacting flows of fresh and salt water. Pieter Hack, founder of REDStack, honoured the NL Lounge with a presentation about their innovative technology. Hack remarked: “At the end of the day, we rely on the Earth’s five available energy sources: solar, geothermal, wind, biomass and hydropower. So the question isn’t if our Blue Energy technology will become mainstream, but rather when it will happen.”

Incoming missions

Delegations from Guinea, France, Peru, Brazil, India, Oman, Vietnam, Malaysia, Mexico, Spain and Chile visited the NL Lounge. Additionally, Partners for Water hosted two platform meetings —one for India and one for Vietnam. These incoming missions served to strengthen the relationship between the Dutch water sector and its international counterparts, leading to fresh perspectives on water-related business opportunities overseas. Willem Timmerman, First Secretary at the Embassy of the Kingdom of the Netherlands in Vietnam, remarked: “Vietnam aspires to become a high-income country by 2025 and achieve carbon neutrality by 2050. Currently, the nation is facing significant water and climate challenges. However, there is a strong willingness to invest in high-quality solutions, resulting in valuable business opportunities for the Netherlands”

Enlightening presentations

“Artificial intelligence (AI) has transformed leak identification from a reactive to a proactive process,” declared Robert Lodewijk. The founder of AI company Hulo gave an engaging presentation about the potential of AI in water systems. Lodewijk continued: “By utilising AI in conjunction with pressure and flow sensors, we can detect, localise and quantify leaks with the highest possible accuracy.”

“We integrate data from diverse atmospheric and soil sensors into a single forecasting system. Through a user-friendly dashboard, farmers receive severe weather warnings and irrigation advise,” shared Lisa Verschuren, from FutureWater. She presented MAGDA, an elaborative weather forecasting system and explained how this data empowers farmers to anticipate and prepare for extreme weather conditions.

These presentations offer just a snapshot of the numerous insightful discussions that took place over the course of the week. Topics ranged from AI and robotic solutions to water energy consumption and socio-technical integration, all woven together by a shared goal: to advance global water security through innovative solutions.

Funding opportunities

“For small and medium-sized enterprises (SMEs), covering working capital needs when exporting can be challenging. That’s where we come in,” explained Marc Cabret from impact investment organisation Invest International. Alongside his colleague Joris Kreulen, he presented the organisation’s financial solutions. Kreulen added, “We offer Dutch and Dutch-linked SMEs aligned with the Sustainable Development Goals tailor-made and blended funding solutions for export, investment and value chain needs .” Invest International is not the only supporter of the water sector. Earlier in the week, Hugo de Vries of Partners for Water highlighted in a discussion on RVO support instruments: “Numerous innovations addressing global water challenges are being developed within the Dutch water sector. The PfW subsidy scheme can play a supportive role in accelerating these innovations.”

Young water experts

Undoubtedly, the youth hold the key to our future. That is why Wavemakers United (WU) and the Young Expert Programmes (YEP) are dedicated to constructing a global impact community and fostering connections among young professionals in the water sector. Partners for Water was pleased to contribute by hosting a facilitated networking lunch in the NL Lounge for young water experts. Young professionals from various sectors within the water sector came together to discuss the future of water and to listen to an inspiring presentation on the work of YEP and WU.

“We all have varied expertise and come from different backgrounds. Progress towards a sustainable and water-secure world happens when we find each other and aim for mutual learning and understanding,” remarked one of the young professionals. It was not only an outreach to the participating water sector but also beautifully encapsulated the essence of the networking event.

NL Lounge

From early morning until late afternoon, the NL Lounge was abuzz with the lively chatter of busy water professionals. Over cups of coffee crafted by skilled baristas, new business ideas were introduced, international connections formed, discussions held and thoughts exchanged on the future of water and innovation. The journey towards a sustainable water world is progressing incrementally – and the visitors of the NL Lounge certainly took a collective step forward.

We reflect on a fruitful week and extend our heartfelt thanks to all our collaborative partners and visitors for their enthusiasm and commitment to advancing a sustainable and secure water future.

What’s happening now and what’s next for Dutch-Indonesian water cooperation? Hosted by Partners for Water, over fifty professionals came together on 26 October during the Dutch-Indonesian Platform Meeting in The Hague.

Attendees, consisting of individuals from knowledge institutions, private-, governmental- and non-governmental organisations, exchanged their ambitions, priorities and opportunities for water initiatives between the Netherlands and Indonesia. Discover their main take-aways.

“What are your aspirations for the Dutch water sector in Indonesia?” asks Lisa Hartog, Delta Coordinator for Indonesia at the Ministry of Infrastructure and Water Management while kicking off the Indonesian platform meeting. With enthusiasm she goes on saying, “Today’s focus is to connect, explore and strengthen the long-term collaboration between the two countries in the water sector.”

She invites the participants to brainstorm on their ambitions, lessons learned and opportunities during engaging breakout sessions. These brainstorm sessions are part of a broader study aimed at identifying the sector’s prospects in Indonesia and explore the best ways the Dutch government can assist in this. The room quickly divides into four groups, with participants actively joining in on lively discussions.

“What I took away from today is that understanding the local culture might be more key to implementing water solutions than knowing the relevant technologies.” – participant brainstorm

Current projects in Indonesia

To explore the current role of the Dutch water sector in Indonesia, various ongoing projects are highlighted. Simon Van Meijeren, from Partners for Water, along with Trang Vu and Bas van Maren – both working for the Dutch consortium Ecoshape, discuss recent initiatives in Indonesia, funded by Partners for Water. “It is crucial to adopt an integrated view of the water problems in Indonesia,” van Meijeren states. “We try to do this through high-level strategic dialogues, co-creating solutions with local communities and improving inter-agency collaborations.” Vu and van Maren wholeheartedly concur. As the audience listens intently, they eagerly share their insights from a scoping mission in Sidoarjo, led by the Ecoshape consortium.

The scoping mission’s objective was to assess the potential of implementing Nature-based Solutions (NBS) to enhance local aquaculture. Van Maren elaborates: “Initially, the focus was on milkfish- and shrimp yield and water quality, but it became clear that regional degradation of the physical system was a significant aspect of the problem.” Vu continues, “While various NBS appear feasible from a physical standpoint, their economic viability remains to be explored.” The Ecoshape consortium aims to integrate the lessons learned from this mission into future NBS project designs.

Curious to discover the results, lessons learned and recommended solutions? Find all the details in the scoping mission’s report provided below this article.

Young professionals

Delving further into Sidoarjo, two young professionals recount their former study experiences in this Indonesian coastal city. Joey de Hamer, currently with the Netherlands Red Cross, elaborates about his thesis study on the social impacts of the Sidoarjo mud volcano. This volcano has spewed hot mud continuously since 2006, displacing tens of thousands of residents and causing significant environmental and infrastructural damage. De Hamer comments, “While the ecological impacts of the mud volcano were broadly recognised, I found it enlightening to learn about the experiences and challenges faced by the nearby residents.”

Meanwhile, Ardiyanti Cahyan, currently at Boskalis, shares her past internship which focused on water management at the Port of Teluk Lamong. Cahyan remarkes, “Being on-site allowed me to truly connect with and better understand the local issues.” Her take-home message? The importance of experiencing the local context for a more profound understanding of the problems at hand.

Change takes time

Straight after his arrival for a work visit to the Netherlands, Adriaan Palm, Deputy Head of Mission at the Dutch Embassy in Indonesia, succinctly summarises the event: “I think we all agree on the significance of engaging the local community to ensure project sustainability. Additionally, I’d like to recognise the value of collaborating with students and emerging professionals. And lastly, change is a gradual process. So, I encourage you to give yourself that time.” As the attendees shift towards the facilitated networking lunch, fresh perspectives and emerging ideas on today’s themes echo amid the lively chatter. While change may take time, the attendees sure don’t waste it.

Keen to keep the conversation going? You are invited to share your thoughts, ambitions or anything else you’d like to discuss with our core team working on the bilateral water cooperation with Indonesia. You can find the team’s contact details in the sidebar.

No food can be produced without fresh water. Given that our fresh water supply is diminishing, we need to carefully manage our scarce supply in order to achieve a future where nobody goes to bed hungry.

That is why the theme of this year’s World Food Day is ‘Water is life, water is food, leave no one behind.’ Simon van Meijeren, programme advisor at Partners for Water, tells us how two Partner for Water projects in South America reflect this theme.

European countries import fruits and vegetables from countries such as Chile and Peru where water availability is a concern. ‘As a result,  we are basically extending our water demand overseas’, says Simon. ‘This means that efficient water usage over there is also a responsibility for us over here. That is why we support collaborative processes that aim to improve production value chains in countries like Chile and Peru.’

Market transformation process

In Chile, Partners for Water works in the Aconcagua valley together with Dutch and Chilean partners. This valley is a major source of fruits such as avocados, that get imported to the Netherlands. However,  the area experiences droughts and has limited water supply, putting a strain on both production and the local ecosystem.

Simon explains: ‘The first steps taken in this collaborative project consisted of hosting a series of webinars in 2021, bringing together a wide range of parties who were either active in the fruit sector or contributing to sustainability efforts down the value chain. Detailed insights about the valley were gained through a catchment-passport: a document that provides a scientific, specific and clear description of the local water situation and key challenges.’

At the same time, a local network of producers and relevant actors called ‘Red Aconcagua.’ was established. The network develops a strategy for achieving sustainable water supplies in the valley and provides guidance on the first practical steps needed to realise this. ‘We will map the water footprint of various producers and identify ways to reduce it. In addition, a market transformation process will begin bringing together international value chain partners such as large exporters and retailers in order to form a shared vision on Aconcagua and determine the first steps necessary to make the value chain more sustainable. By doing this, we are engaging with both local and international stakeholders on a shared sustainability mission.’ says Simon.

Water stewardship

‘We’re focusing on similar issues in Peru with the Water Stewardship project’, Simon adds. ‘There, a coalition of retailers, traders, governments and social initiatives have come together to make the fruit and vegetable value chain more resilient by, for example, strengthening the catchment’s water cycle, conserving biodiversity, reducing soil runoff and improving community livelihoods.’

These initiatives are incorporated into an overall water stewardship plan for the area. ‘The strength lies in scaling up water solutions together reducing costs that you would incur  if you tried to address water risks in your value chain on your own’, Simon explains.

Collective action

These two projects differ in terms of their approach: ‘In Chile we started from a shared vision’, Simon says. ‘We formed a coalition and gradually built up trust through developing and executing joint plans together. Whereas in Peru, the coalition already existed. We started with a collective action through interventions and  cooperation. This enabled us to build trust in order to develop a shared ambition and a long-term plan. We built the relationship by doing.’

What these projects have in common is their key success factor: involving the whole value chain. ‘To realise lasting positive change, every party of the value chain needs to contribute. From producer, importer, retailer to consumer.’ Simon says

Raising awareness is crucial to achieve this: ‘Ask yourself what part can you take responsibility for. Retailers need to ask for a product which is sustainably produced and consumers must value this by paying a fair price. A producer needs to ask: do I want to generate maximum output in a relatively short time, or do I want to produce less, more sustainably, so that I can continue production twenty years from now? With collective action, things can really change’, concludes Simon.

The Water Balance Pilot project is an initiative of Henk Ovink, the Netherlands’ first Special Envoy for International Water Affairs. It is funded by Partners for Water, in partnership with the city of Chennai, UN-Habitat and Resilience Cities Network and supported by the UN High-level Panel on water, amongst others.

Blueprint for the city

The project serves as a model for how a city can become water-secure using Nature-based Solutions. It harvests rainwater and treats wastewater before recharging into the underground aquifer through infiltration gardens. Eva Pfannes, Director of Ooze Architects and Urbanists and team leader of City of 1000 Tanks shared details about the project: “The Water Balance Pilot project is the  first example that will reach its full potential when replicated in institutions across the city. In parallel, we plan to scale it up through a flagship project in Mylapore.”

Partners for Water

Partners for Water is honoured to make the Water Balance Pilot project financially possible. The objectives of the Partners for Water programme are to encourage knowledge sharing, innovation and an integrated approach. Through these efforts, we strive to contribute to the expansion of sustainable solutions that enhance water security. The City of 1000 Tanks seamlessly exemplifies these principles. The pilot initiative has gathered valuable knowledge and experience that can be harnessed in scaling up this innovative solution across various parts of the city and potentially beyond.

Dual-aquifer recharge wells

Generated by the 300 residents, the Water Balance Pilot project collects 27,000 litres of wastewater per day which is then treated in two stages: the first stage is where two underground anaerobic tanks, rich with microorganisms, work on the pollutants to achieve 80% of the treatment capacity and the following stage is where the water is then allowed to flow through created wetlands with helophytic plants enabling aerobic treatment. No toxic chemicals are used and the project is completely supported by solar power. Bad odours and mosquito breeding are also eliminated.

The treated water is then released to the ground through infiltration gardens. This minimum-maintenance project is equipped to harvest rainwater during Chennai’s short and intense monsoons. Dual-aquifer recharge wells collect, store, filter and finally recharge rainwater to the shallow and deep aquifers.

What is next?

To scale-up the Water Balance project to other parts of the city, the City of 1000 Tanks-team aims to involve the government such as the Chennai Metropolitan Water Supply and Sewerage Board and the Greater Chennai Corporation for the greater good. In order to make Chennai water secure, they also welcome the participation from resident welfare associations, vulnerable communities, CSR partnerships and institutions.

With gratitude we look back at the ‘Social Inclusion in Water Climate Adaptation – Making a Transformation’ event, which took place on 12 September 2023 in Utrecht. Below you will find a short recap of the experiences shared by various participants.

“What I’ve learned during the event the importance of embracing diverse views and attitudes when facing collective challenges. Instead of imposing my own perspectives, I aspire to recognize the value in each other, genuinely listen, and accept potential differences as a starting point. From there, we can collectively acknowledge and address our challenges, working together to find resolution.” – Piebe Hoeksma, Dutch Water Authority

“My most significant takeaway from the Social Inclusion event is the inspiring work people are already doing to address water security, aligning with my work on rainwater catchment projects in northern Kenya. I’m enthusiastic about exploring the ideas on social inclusion I’ve encountered at the event, with a view to making a lasting impact on my marginalised community in Kenya.” – Augustine Lenamoe, Npydo

“If I were to reflect on my experience of the Social Inclusion event, I’d highlight a valuable insight: it’s crucial to return to the source of our actions. Often, we assume we know what marginalised groups need and plan projects accordingly, but in reality, we know very little about their lives and circumstances. Instead, it’s wiser to ask them directly, shaping our project activities and defining short-term, mid-term and long-term goals based on their actual needs.” – Priodarshine Auvi, Oxfam Novib
