A New Era for Water Solutions via Disruptive Sustainability
Water scarcity is a critical global issue, impacting millions and threatening the future of countless communities. With an expected displacement of 700 million people by 2030 due to lack of access to clean water, the need for innovative water solutions has never been more urgent. The world is facing severe shortages, and traditional water management solutions are struggling to keep up with rapidly growing demand. This is where disruptive technologies, powered by innovative financing, come into play.
Disruptive technologies such as solar desalination, atmospheric water generators, and smart water grids offer transformative potential but face significant financial hurdles. To address these, we must rethink traditional funding models and embrace new approaches.
Let’s take a closer look at how innovative financing solutions and disruptive technologies are converging to tackle one of the most pressing issues of our time.
The Problem: Inadequate Financing for Water Innovation
The water sector faces a severe funding gap, particularly for groundbreaking technologies. Traditional methods of financing, like tariffs, taxes, and transfers (the "3Ts"), often fall short when it comes to the capital-intensive nature of projects like desalination or closed-loop water recycling systems. As it stands, OECD’s report shows that the 3Ts only contribute 32% of water innovation funding, and this might be a stretch.
Here’s what to keep in mind:
- Water scarcity is expected to grow exponentially, affecting 1.8 billion people by 2025.
- The OECD's 2024 report highlights that despite environmentally beneficial subsidies and taxes, financing radical water technologies remains a significant challenge.
- Solar desalination and smart water grids are potential solutions but are delayed due to funding shortfalls.
The Action: New Financing Models to Propel Innovation
To accelerate the implementation of disruptive water technologies, we must adopt new and creative financing models. This shift involves going beyond the "3Ts" and embracing innovative funding tools such as blended finance, green bonds, and public-private partnerships (PPPs).
Blended Finance and Public-Private Partnerships (PPPs)
Blended finance, combining public funds with private capital, is becoming a key strategy to reduce risks and attract investments in high-risk projects like solar desalination or water recycling systems.
Real-life Example: In Kenya, the Mombasa Desalination Plant, a solar-powered project, was made possible through a PPP. By blending public and private funding, this project now provides clean, sustainable water to a region previously plagued by scarcity.
Green Bonds and Climate Finance
Green bonds are a critical tool for funding sustainable water projects, allowing for investments in atmospheric water generators and smart water grids that combat both water scarcity and climate change.
Real-life Example: Mexico issued green bonds to fund the development of smart water systems, which monitor and reduce water leakage using IoT-based solutions. This resulted in a significant reduction in water wastage in urban areas, a testament to how climate finance can directly impact water sustainability.
Development Assistance and Philanthropy
Traditional development assistance (ODA) and philanthropic funding continue to play an important role in de-risking disruptive projects in underdeveloped regions. Traditional aid is being channeled into projects that have the potential to disrupt conventional water management practices.
Real-life Example: The Bangladesh Water Partnership Project enabled textile factories to implement closed-loop recycling systems that recycle 95% of their wastewater, reducing environmental impact while addressing water scarcity in the region.
The Solution: Scaling Disruptive Water Technologies
Scaling these technologies requires a combination of financing mechanisms and innovative water solutions. By pairing these tools, we can unlock the full potential of sustainable water technologies.
Renewable Energy-Powered Desalination
Problem: Desalination is energy-intensive and traditionally relies on fossil fuels, making it unsustainable.
Action: The integration of solar-powered desalination, smart water grids, and atmospheric water generators (AWGs) into mainstream water management has the potential to revolutionize the sector. The Neom Desalination Plant in Saudi Arabia utilizes solar energy to power desalination processes, made possible by blended finance and green bonds.
Solution: Solar desalination provides affordable drinking water while significantly reducing carbon emissions. This project has set the stage for affordable and sustainable drinking water solutions in one of the world’s driest regions.
Smart Water Grids
Problem: Water loss due to inefficiencies in urban systems is a significant challenge.
Action: Cities like Singapore have introduced smart grids using green bonds and private investments. These grids use real-time monitoring systems to detect leaks and optimize water distribution.
Solution: Real-time monitoring reduces water waste and operational costs, improving both efficiency and sustainability.
Atmospheric Water Generators (AWGs)
Problem: Remote areas lack access to reliable freshwater sources.
Action: PPPs and climate funds have helped scale AWG projects in Sub-Saharan Africa, where traditional infrastructure is inadequate.
Solution: Solar-powered AWGs, such as Watergen units, offer water from the air, transforming how remote communities access water.
Rapid Urbanization and Aging Infrastructure
The issue of water scarcity is further compounded by the rapid urbanization and aging infrastructure seen in many cities, particularly in Asia and Africa. Urban centers in these regions are grappling with the combined pressures of flooding, water scarcity, and poor wastewater treatment systems. Traditional urban water management strategies are being stretched to their limits by these challenges. However, innovative approaches such as stormwater drainage systems and decentralized wastewater treatment offer scalable, flexible solutions. China’s Sponge Cities initiative, which absorbs and reuses rainwater, is an example of how cities can address both water scarcity and flooding concerns through sustainable urban planning.
Beyond technological innovation, institutional reforms are critical for sustainable water management. Policies must be adaptable to local conditions, and community involvement is key. In Copenhagen, the integration of local stakeholders into water management decision-making processes has led to the development of resilient, adaptable water systems. Such reforms are essential to ensure that innovations in water management are not only technologically advanced but also socially sustainable.
The Global Water Crisis and Circular Water Economy
Water Scarcity's Growing Impact
Around 1.2 billion people face physical water scarcity, while another 1.6 billion experience economic water shortages due to inadequate infrastructure. The UN estimates that by 2030, up to 700 million people could be displaced by water stress.
Real-Life Example: Singapore's Circular Water System
Singapore has pioneered a circular water economy through its "NEWater" program, recycling wastewater into high-grade water for industrial use. This approach has allowed the country to reduce its reliance on imported water.
Industry Events as Catalysts for Change: Learning and Knowledge Sharing
One of the most powerful ways to drive change in the water sector is through industry events like WEFTEC (Water Environment Federation's Technical Exhibition and Conference). Events like WEFTEC bring together the brightest minds in the water industry, from global disruptors to innovators focused on sustainable solutions. Companies, like Tank Depot, can leverage these events as learning hubs and platforms for exchanging ideas.
Although Tank Depot won’t be exhibiting at the WEFTEC 2024, attending and interacting with industry leaders and disruptors provides the perfect opportunity to observe emerging trends, share insights with peers, and absorb best practices that promote sustainability.

Nature-Based Solutions (NBS) and the Water-Energy Nexus
Nature-Based Solutions (NBS)
Nature-Based Solutions, like wetland restoration, offer sustainable alternatives to costly infrastructure.
New York City, for example, invested in forest restoration and wetland protection in the Catskill/Delaware watershed, which provides 90% of the city’s drinking water. By preserving these natural filtration systems, New York avoided the need to build a costly water filtration plant, saving an estimated $8 billion in construction costs and $300 million annually in operational expenses.
The Water-Energy Nexus
Equally important is the Water-Energy Nexus, which highlights the interdependency of water and energy production. Water is required to generate energy, and energy is needed to treat, distribute, and heat water. Improving efficiency in both sectors can drastically reduce environmental impact. In Denmark, the city of Aarhus has taken the lead with one of the world’s first energy-neutral wastewater treatment plants. This system, powered by biogas and renewable energy, generates more energy than it consumes. In addition to pumping water to the residents and powering the plant, any excess electricity is sold into the grid. How cool is that?
The success of Aarhus is now being replicated worldwide as cities strive to reduce their environmental footprints.
Digital Transformation and Smart Water Management
The digital transformation of the water sector is creating more efficient, data-driven solutions.
Case in Point: Singapore’s smart water grids use IoT sensors to monitor water usage and detect leaks in real-time. This has drastically reduced water wastage and operational costs.
