Drop by drop: Solving the textile industry’s water crisis

The textile industry has a water problem. From cotton fields to dye houses, every stage of production leaves a mark on the world’s freshwater systems. But behind the statistics we’ve all seen—such as how it takes thousands of liters to produce a single T-shirt—there’s a deeper story unfolding in the rivers and wetlands where that impact is felt most acutely. WWF’s latest Drop by Drop report offers a look at how tangible, on-the-ground action can help some of the world’s most water-stressed basins start to turn a corner.

In Turkiye’s Buyuk Menderes Basin, a biodiversity hotspot and home to a massive share of the country’s cotton and textile exports, regenerative farming pilots have delivered striking results. One farm cut its water use by 60%, saving 58,000 cubic meters annually. These practices aren’t just good for ecosystems—they can be profitable too, with a mere two- to three-year payback period when paired with government support. That kind of ROI reframes the question from “should we?” to “how fast can we scale?”

Efforts in Pakistan’s Indus River Basin, home to 96% of the country’s renewable water resources, focused on restoring balance in a landscape pushed to its limits. The basin, which supports some 96% of the country’s renewable water resources, faces mounting pressure from textile and leather sectors. WWF helped implement more than 1,000 rainwater harvesting systems, 112 groundwater recharge wells, and 77 greywater reuse systems. Additionally, workshops facilitated by WWF have already sparked movement in the banking sector, with many local institutions now planning to design green financing mechanisms for Small-to-Medium Enterprises (SMEs).

In Vietnam, WWF helped a denim facility upgrade its wastewater recycling system using an ion exchange filtration method that paid for itself in just 11 months thanks to its low upfront cost. The broader water stewardship effort there, now backed by over $1.6 million in secured funding, plans to expand into aquaculture and beverages while experimenting with industrial-scale water reuse and nature-based solutions. Leading global beverage brands are joining the table, eager to future-proof their operations in a region that grows half of Vietnam’s rice and 70% of its aquaculture exports.

Meanwhile, in India’s Noyyal and Bhavani Basins, home to Tiruppur, the knitwear capital of the country, WWF worked with factories to identify efficiency upgrades that could save 128 million liters of water and over 2 million kWh of electricity annually. The program also reached beyond industrial sites, supporting wetland restoration with floating fountains to improve water quality, bar screen chambers to block solid waste and invasive plants, and even dragonfly surveys to track ecosystem health.

And finally, in China’s Taihu Basin, WWF is helping lead a shift toward basin-wide resource management. The newly released “Industrial Park Guidance 2.0” refines water management practices, introduces a Water Stewardship Index, and includes tools to quantify water savings and carbon reductions, offering a more integrated, data-driven approach to shared infrastructure and sustainable operations.

The bottom line? Yes, the textile sector has a water problem—but it also has a growing number of people solving it. Quietly. Effectively. One river basin at a time. If we can build on these innovations and these partnerships, we can secure ample water resources—not just for ecosystems, but for the economies and communities that depend on them.
