Measurable Water Security at Scale

Water Resilient Cities

We work with cities to understand water vulnerability, identify priority interventions and connect policy with technology, finance and implementation.

The aim is not another static framework, but a practical pathway from assessment to action.

Select a dimension

Whether the city can count on enough water to meet what its people and its economy need.

Whether the city's systems for drinking water, sanitation and drainage reach everyone and hold up under strain.

How exposed the city's water is to drought, flooding and other extremes of weather.

Whether the rules, institutions and responsibilities for the city's water are clear and work together.

Whether the city can fund its water systems, from building them to running and maintaining them.

Whether the city draws on technology that helps it supply, save and protect its water.

Whether the city measures its water well enough to see a problem coming.

How well the city's people and communities can cope with a disruption to their water and recover from it.

TWF Water Score

The TWF Water Score creates comparable, decision-useful assessments of water resilience across cities, countries, corporates and basin systems.

It combines performance with data reliability so decision-makers can understand not only where risk exists, but how confidently it can be measured.

A World of Connected Water Systems

Water does not follow political boundaries.

Rivers cross borders. Aquifers sit beneath multiple jurisdictions. Supply chains connect water use in one country with consumption in another. Cities, agriculture, energy systems and industries can depend on the same basin while operating under entirely different regulatory frameworks.

Yet water policy is still predominantly organised around administrative boundaries.

TWF approaches water governance from the system outward: beginning with the water system itself, then mapping the governments, markets, infrastructure, communities and capital that depend on it.

Policy Built for Yesterday's Boundaries

Many of the institutions, regulations and agreements governing water today were designed for a world with different populations, different climate conditions, different technologies and very different patterns of economic activity.

They often remain fragmented across jurisdictions, sectors and ministries, even where the underlying water system is shared.

The result is a structural mismatch:

  • Water moves across borders.

    Policy usually does not.

  • Water connects sectors.

    Regulation often separates them.

  • Technology can change quickly.

    Governance usually changes slowly.

  • Capital moves globally.

    Water decisions remain highly local.

Water resilience therefore requires more than updating individual policies. It requires new ways of coordinating across boundaries.

TWF works on governance models that connect jurisdictions, sectors and stakeholders around the water system they actually share.

River Basins & Transboundary Water

Water systems do not stop at administrative borders.

We work at basin level to bring together governments, communities, businesses, investors and other stakeholders around shared water systems, with a focus on governance, investment, data and long-term resilience.

The objective is not simply better coordination. It is to create governance structures capable of responding to the economic, environmental and technological realities of a shared water system.

We map river systems not only as governance units, but as investable economic systems.

One River, Many Stakeholders

Activate stakeholders

  1. Upstream

  2. Downstream

  • Countries, Upstream The countries where the river rises, whose choices about its water travel downstream across their borders.

  • Cities, Upstream Cities that draw on the river early and return to it what they use, for everyone below.

  • Agriculture, Upstream Farms that take water for their land before the river reaches the users below.

  • Industry, Upstream Industry that takes water for its work and returns it to the river others use further down.

  • Energy, Upstream Energy, from dams to plants that draw on the river, that shapes how much water passes on and when.

  • Communities, Upstream People who live along the river near its source, and whose use of it reaches those below.

  • Infrastructure, Upstream Dams, intakes and works upstream, which change the water every user below receives.

  • Capital, Upstream Investment in what is built and run upstream, whose effects travel down the river.

  • Countries, Downstream The countries the river reaches last, which share in what is decided upstream without deciding it.

  • Cities, Downstream Cities that draw on water every user above them has already taken from and returned to.

  • Agriculture, Downstream Farms that depend on what the river still carries by the time it reaches them.

  • Industry, Downstream Industry that works with the water, in amount and in quality, that reaches it from upstream.

  • Energy, Downstream Energy that needs the river to arrive with enough water to run on.

  • Communities, Downstream People who live along the river further down, and live with what is decided above them.

  • Infrastructure, Downstream Infrastructure downstream, built for a river whose flow and quality are shaped above it.

  • Capital, Downstream Investment downstream, which carries risks that begin upstream of what it pays for.

Investing Along Rivers

Water systems create economic systems.

Rivers connect cities, agriculture, industry, energy, logistics, ecosystems and communities across entire regions.

Investment opportunities therefore rarely sit in isolation. They emerge along the full river system, where infrastructure, technology, land use, industry and policy interact.

TWF maps these relationships to understand where water risk, economic activity and investable opportunity overlap.

Our river-based market approach looks beyond individual projects and asks:

Where along the system can capital create the greatest resilience, additionality and economic value?

This can include opportunities across:

  • Water Infrastructure
  • Treatment & Reuse
  • Industrial Water
  • Agriculture & Irrigation
  • Energy & Cooling
  • Digital Monitoring & Data
  • Nature-Based Infrastructure
  • Urban Resilience
  • Logistics & Economic Infrastructure

Why

Because water risk is spatial, interconnected and cumulative.

A single intervention can shift risk upstream or downstream, create new constraints elsewhere in the system or unlock value across multiple sectors at once. Looking at isolated assets misses those relationships.

Investing along rivers allows us to identify where:

  • One intervention can unlock several outcomes

  • Shared infrastructure can serve multiple users

  • Technology can resolve a system-wide bottleneck

  • Capital can reduce risk across an entire corridor

  • Policy alignment can make previously stranded opportunities investable

It also helps distinguish between projects that simply perform well on their own and interventions that improve the resilience of the wider water system.

The objective is not to optimise one asset. It is to strengthen the system around it.

River Investment Map

We do not only invest in water assets. We invest along water systems.

That means identifying how value and risk move along a river, where intervention can unlock multiple outcomes, and where Capital provides the resources required to move.Explore Capital can strengthen the resilience of the wider system rather than optimise a single asset in isolation.

Cross-Boundary Governance

The next generation of water governance must work across more than national borders.

It must connect:

  • Countries across shared basins
  • Cities across common infrastructure systems
  • Public and private actors
  • Water, energy, food and industrial policy
  • Upstream and downstream users
  • Physical water systems and financial systems

TWF develops and convenes cross-boundary approaches designed around the actual system being governed. This includes new models for basin-level cooperation, shared data, coordinated investment, common resilience targets and governance structures capable of surviving political and project cycles.

National Water Resilience

We support governments in assessing water resilience across infrastructure, economic exposure, policy, governance, technology and investment.

The objective is to identify structural weaknesses and translate them into implementable priorities.

Select a dimension

How much water the country has to draw on, set against the demands placed on it.

How much water the country's households, farms and industries need, and where that need is heading.

Whether the country's systems for drinking water, sanitation and storage reach its people and hold up under strain.

How much of the country's economy depends on water, and what a shortage or a flood would cost it.

Whether the country's laws, institutions and plans for water are clear, coordinated and carried out.

Whether the country is ready for investment in water, with projects worth funding, clear rules and the means to deliver them.

How far drought, flooding and other extremes of weather put the country's water, people and economy at risk.

Corporate Water Resilience

Water risk increasingly affects operations, supply chains, asset values and long-term competitiveness.

We help companies understand that exposure and connect resilience priorities with measurable interventions, technologies and financing pathways.

Policy & Governance

We support the development of policy environments that allow proven technologies to be deployed, capital to scale and institutions to act with greater clarity.

Our approach is non-prescriptive and implementation-led, recognising that different water systems require different combinations of policy, finance and technology.

Research & Publications

We produce research designed to inform decisions rather than simply describe problems.

Our work focuses on the structures, incentives, risks and opportunities that determine whether water solutions can move from concept to implementation at scale.

Water Systems Are Connected. Governance Should Be Too.

TWF works with cities, governments, corporates, basin organisations and international partners to build policy and governance structures around the systems they are intended to protect.
