— In April, the World Bank, together with several multilateral financial institutions, launched a ten-year action plan called “Water Forward.” Its message is clear:

Water security supports roughly 1.7 billion jobs worldwide — and the logic of how we achieve it is undergoing a profound shift.

For decades, the dominant narrative in international water cooperation was about “engineering marvels”: dams, long-distance water transfers, large-scale desalination plants. But now, the World Bank has made its stance clear — the priority is no longer about “finding more water,” but about “using less” and “using better.”

The four priority areas of the Water Forward plan have nothing to do with traditional civil engineering:

1. Urban leak reduction

In many developing countries, non-revenue water can be as high as 30–50%. By deploying smart meters, district metering, and pressure management, every 1% reduction in leaks is equivalent to gaining millions of tons of water without building a single new source. This “negative-cost water” offers an extremely high economic return.

2. Irrigation modernization

Agriculture consumes about 70% of the world’s freshwater, yet traditional flood irrigation achieves less than 50% water-use efficiency. Drip irrigation, micro-sprinklers, and soil-moisture-based smart irrigation systems can push efficiency above 80%. This is one of the most investment-worthy “blue oceans” at the intersection of food security and water security.

3. Water reuse

The linear “take-use-discharge” model is being broken. Whether for industrial reclaimed water, municipal non-potable use, or agricultural irrigation, wastewater treatment plants are transforming from “end-of-pipe facilities” into “urban water sources.” By elevating water reuse to a strategic priority, the World Bank signals long-term demand for membrane technology, advanced oxidation, smart monitoring, and other niche segments.

4. Data-driven planning

This may be the most underestimated area. Using satellite remote sensing, AI forecasting, and big data modeling, it’s possible to improve the efficiency of water allocation by more than 20% without laying a single meter of pipe. As the World Bank emphasizes: data is a cheaper and more powerful water management tool than concrete.

After reading this blueprint, anyone in the water industry will be asking: where are our future opportunities?

The World Bank’s plan sends three clear signals to water professionals — let’s unpack each one:

Signal 1: Brownfield opportunities come before greenfield.

Developed and emerging economies are no longer mainly competing to “grab more water.” Instead, they’re focused on “making better use of the water they already have.” Leakage control in urban networks, retrofitting and upgrading old wastewater plants, raising water recycling rates in industrial parks — these traditionally seen as “after-sales markets” — are becoming the biggest growth poles.

Signal 2: Technologies that can prove their economics will win capital first.

In the past, water projects were often driven by regulatory compliance or political commitments. Under the new framework of “water security economics,” the World Bank and private capital want to see real water pricing, cost-benefit analysis of water savings, and quantifiable risk reduction. Technologies with clear energy-saving and cost-reduction benefits — such as membrane treatment, AI-optimized chemical dosing, and low-energy desalination — will be adopted faster than those that look “cool” but can’t close the financial case.

Signal 3: Cross-sector capability is a competitive edge.

An implicit requirement of the Water Forward plan is that water companies need to know not just how to treat water, but also how to talk to agriculture, urban planning, and energy departments. For example, using waste heat from data centers for sludge digestion, or selling reclaimed water to industrial parks for cooling — these solutions that cut across traditional boundaries are exactly what the World Bank recognizes as models of “system resilience.”

The launch of Water Forward marks a new phase in global water governance: moving from “solving scarcity” to “managing water as an economy.” For water companies, this is not just a signal of market expansion — it’s an upgrade in service logic: shifting from providing equipment to providing “water efficiency.”

As one line repeated during the plan’s launch put it: “Water used to be a free public good, but scarcity is no longer cheap.”

When the World Bank starts talking about pipes, reservoirs, and recycled water in the language of economics, the rules of the game have already changed. And we happen to be standing right at the cusp of that change.
