In this article, we take a look at the 15 countries that waste the most water per capita. You can skip our detailed water-treatment-industry analysis and go directly to the 5 Countries That Waste the Most Water.
Global Water Treatment Industry Trends
Water availability is becoming an environmental issue in many places. In some regions, droughts are becoming more common, negatively impacting people’s health and productivity. On a global level, water scarcity and droughts have become a threat to sustainable development and biodiversity.
While the world produces approximately 380 trillion liters of wastewater each year, 2.4 billion people live in water-stressed countries as of 2020 data. According to the UN SDG 6, 2.2 billion people lacked safely-managed drinking water, including 703 million without basic water service in 2022. 2 billion people had no basic hand washing facilities, whereas 3.5 billion people lacked safely-managed sanitation.
All these numbers show that while wastewater quantity is on the rise, there’s a high demand for clean water in the world. By 2030, if the wastewater treatment industries don’t quadruple in size, billions of more people will lack access to these necessities. By managing and treating water more efficiently, countries can better manage their food and energy production and further contribute to decent work and economic growth.
Entering 2024 with climate change, growing population, and advancement in technologies, the market of wastewater treatment is also evolving. The main reason for the growth in the water treatment market is the depletion of freshwater resources, which is worrisome on a global level. Therefore, the market has adopted new trends and techniques to better manage and treat wastewater.
Digitalization is one of the most significant trends adopted in the wastewater treatment industry. With increasing global water demand and the need to develop infrastructure, digital water management has become a crucial part of the water treatment industry. It helps in better control over the quality and quantity of the water, using technologies like Artificial Intelligence (AI), geographic information systems (GIS), digital twins, and augmented or virtual reality. PipePredict is one of the companies that delivers digital leakage detection using AI, sensors, and digital twins.
Outlook: 10 Years From Now
The global water and wastewater treatment market size is expected to grow to around USD 572.2 billion by 2032 from USD 295 billion in 2022, with a CAGR of 6.9%, as noted by Precedence Research. In 2023, the market cap was USD 313.88 Billion, and the total water consumption stood at around 4 trillion m3 annually.
Out of the total global consumption, approximately 10% of water is wasted annually. The countries using the most water are India and China. On the other hand, Costa Rica has the least annual water waste production, 42.09 m3 per capita. In terms of cities, Mexico is the city that wastes the most water — around 44% of its water consumption goes as wastewater. In the list within this article, I’ll discuss more about the countries that waste the most water.
From washing dishes to watering plants, water waste production happens all the time. In our houses, a leaked toilet alone can waste around 15,000 gallons of water a month. Water may be a commodity that we don’t think much of while using, but it’s essential for our existence. On the industrial level, the use and waste of water has increased significantly more. In the United States alone, 300 billion cubic meters (m3) of water are used by the industrial sector annually. So naturally, the water industry is a multibillion-dollar one.
The key players in the water industry are American Water Works (NYSE: AWK), Essential Utilities (NYSE: WTRG), Xylem Inc. (NYSE: XYL), and American States Water Company (NYSE: AWR). Together, they share a total market cap of USD57.71 billion, with American Water Works (NYSE: AWK) having a market cap of 24.40 billion USD, Essential Utilities (NYSE: WTRG) having a market cap of 10.07 billion USD, and American States Water Company (NYSE: AWR) having a market cap of 2.84 billion USD.
These numbers are likely to go up as many climate experts expect droughts and extreme weather events to become more common in the coming years, which will likely raise water prices. For the same reason, leading companies in the water industry have begun looking at expansion and growth plans. By 2025, Essential Utilities (NYSE: WTRG) aims to invest about $3.3 billion towards the improvement of its water, wastewater, and natural gas infrastructure. Similarly, American Water Works (NYSE: AWK) plans to invest about $15 billion in its operations by 2027. American States Water Company (NYSE: AWR) has not yet discussed its plans for expansion and investments, but they are making significant strides. In 2023, the company’s well-known subsidiary, Pennsylvania American Water, sealed the deal for the acquisition of Appalachian Utilities, Inc.

Our Methodology
For our list of the most water-wasting countries, we used data from OECD, a report published by the UN Statistics Division, and a research study published by Earth System Science Data. We ranked countries based on their annual wastewater generation. We’ve also discussed annual water consumption and withdrawal within the list. The list is in an ascending order metrics-wise.

Here are the 15 countries that waste the most water.
15. Costa Rica
Annual Water Waste Production: 42.09 m3 Per Capita
Known for its natural beauty and biodiversity, Costa Rica has a population of over 5.2 million. As of 2017, it had an annual water withdrawal of 1646.41 m3 per capita. The number dropped to 615.63 m3 per capita in 2021. In the same year, they produced 42.09 m3 of water waste per inhabitant.
The wastewater collection and treatment has been an environmental issue in the country, particularly in the northern region. To tackle the issue with innovative and technical solutions, the United Nations Environment Programme (UNEP) and the Inter-American Development Bank (IDB) have started a partnership project, CReW+, in Costa Rica and 17 other countries in the Wider Caribbean Region (WCR). The Global Environment Facility (GEF) is funding the project.
