Water is crucial for energy production, industrial processes, and agriculture, but some sectors use far more water than others. With water scarcity becoming an increasingly pressing issue, it is important to identify which industries are the most water-intensive and how they can reduce their water consumption. This introduction will explore the industries that constitute the greatest water usage, the reasons behind their high water consumption, and potential strategies for more sustainable water management. By examining water-intensive industries, we can highlight areas for improvement and develop targeted solutions to address water scarcity concerns.

What You'll Learn
Domestic water use
Toilet flushing constitutes a significant portion of domestic water use, accounting for about 30% of residential water consumption in the United States. This high percentage is attributed to the large amount of water used per flush in traditional toilets. However, upgrading to more water-efficient models can significantly reduce water usage. Other factors that influence indoor water usage include the number of residents in a household and the specific water-using behaviours of individuals.
Outdoor water use accounts for approximately 30% of household water consumption in the United States. This percentage can be higher in drier regions and areas with more water-intensive landscapes, such as the arid West, where landscape irrigation is common.
While water is essential for various domestic activities, it is important to recognise that less than 1% of the Earth's water is readily available for human use. The majority of water on Earth is saltwater found in oceans or freshwater frozen in polar ice caps, inaccessible for practical purposes. This limited supply of usable water underscores the importance of water conservation and the need to promote efficient water usage in domestic settings.
WaterSense, a program offered by the US Environmental Protection Agency (EPA), assists consumers in understanding their water usage and provides guidance on reducing water consumption through efficient products and practices. By adopting water-efficient technologies and behaviours, individuals can play a crucial role in conserving water and ensuring its sustainable use for future generations.

Industrial water use
Water is essential for life, and while it might seem abundant, less than 1% of it is available for human use. The rest is either saltwater in oceans, freshwater frozen in polar ice caps, or inaccessible for practical usage. Water is used for a wide range of purposes, from drinking and cleaning to irrigating crops, producing electricity, and supporting local businesses and industries.
In New York, approximately nine billion gallons of water are withdrawn daily from various water sources, including lakes, rivers, streams, and groundwater. While thermoelectric power generation accounts for the highest proportion of water usage at 54%, industrial water use constitutes about 5% of the total water withdrawn. This industrial water use includes water withdrawals for fabricating, processing, washing, diluting, cooling, or transporting products, as well as for sanitation within manufacturing facilities.
Water conservation is a critical aspect of responsible water usage. Conserving water saves energy and money, helps protect the environment, and ensures the availability of this precious resource for future generations. Programs and initiatives, such as the WaterSense calculator, aim to help households and industries reduce their water consumption by promoting more efficient products and practices.
Water usage in industries is a significant aspect of water consumption, and it plays a vital role in supporting businesses and manufacturing processes. By understanding the extent of industrial water use and implementing conservation measures, we can strive for more sustainable water management practices.

Toilet flushing
The amount of water used per flush has decreased over time. Before 1980, toilets used as much as 7 gallons per flush (GPF). From 1980 to 1992, the average flush volume was reduced to 3.5 GPF, although some toilets still used up to 5 GPF. In the mid-to-late 1980s, low-flow and ultra-low-flow toilets emerged, using 1.6 GPF. In 1993, the standard flush volume was further lowered to 1.6 GPF, and modern toilets typically use this amount. However, newer toilet models may use even less, with some using only 1.28 or 1.2 GPF.
There are ways to reduce water usage when flushing toilets. Upgrading to more efficient toilets can significantly decrease water consumption. Dual-flush toilets, for example, offer a milder flush option that uses less water and a regular flush option with a slightly higher GPF. Water-saving toilets include vacuum-assisted flush, gravity-assisted, pressure-assisted, and composting toilets. Additionally, if replacing the toilet is not an option, there are hacks to reduce water usage per flush, such as placing a brick or a plastic bottle filled with water in the tank to reduce the total amount of water it holds.
While flushing toilets account for a significant portion of water usage, it is important to note that water is used in various other ways in daily life, including for personal hygiene, cooking, and cleaning. Additionally, water is used in industries and businesses, such as for manufacturing, agriculture, and energy production.

Outdoor water use
Water is an essential resource that supports our communities and daily lives. While the Earth is mostly covered in water, less than 1% is accessible for human use, highlighting the importance of responsible water management.
Watering lawns and gardens constitute a substantial portion of outdoor water usage. In fact, more than half of outdoor water is dedicated to maintaining the aesthetics and greenery of residential landscapes. Inefficient irrigation methods further contribute to water wastage, with estimates suggesting that up to 50% of irrigation water is lost due to evaporation, wind, or runoff.
To promote water conservation and reduce wastage, it is recommended to adopt water-efficient practices and technologies. The U.S. Environmental Protection Agency's (EPA's) WaterSense program is an excellent resource for homeowners aiming to decrease their water footprint. The program offers professional certification in water-efficient irrigation techniques and provides a label for products that meet their standards. By employing WaterSense-labeled irrigation controllers, households can save nearly 9,000 gallons of water annually by tailoring watering schedules to local weather conditions.
Additionally, simple behavioral adjustments can significantly reduce outdoor water usage. For instance, instead of watering grass daily, it is advisable to test the lawn by stepping on a patch of grass; if it springs back, it doesn't require additional water. Choosing regionally appropriate plants for landscaping can also create a water-smart and aesthetically pleasing outdoor space.

Water for energy
Water is essential for life on Earth, and humans have been harnessing its power for thousands of years. While water might seem abundant, less than 1% is available for human use, with the rest being saltwater, freshwater frozen in polar ice caps, or otherwise inaccessible. As populations and demands on freshwater resources increase, water management becomes a growing concern.
One significant use of water is in meeting energy needs. Hydropower, or hydroelectric power, is a renewable and affordable source of energy that uses the natural flow of water to generate electricity. It is one of the oldest and largest sources of renewable energy, with a long lifespan and low maintenance, operation, and fuel costs. Hydropower facilities can vary in size, from large dams like the Hoover Dam to smaller, "damless" facilities that channel part of a stream through a powerhouse. As of 2023, all but two US states (Delaware and Mississippi) use hydropower for electricity, with states like Washington, Idaho, and Oregon relying on it for over 60% of their power.
The benefits of hydropower extend beyond electricity generation. Hydropower plants can provide immediate power to the grid during outages, and they also offer flood control, irrigation support, and water supply benefits. However, installation costs for large hydropower facilities can be high, mainly due to civil construction and electromechanical equipment expenses. Proper selection of location and design can help minimize these costs.
While hydropower is a clean and renewable energy source, it is important to consider water usage and management in the context of other energy sources and industrial processes. Water is used in various sectors, including agriculture, manufacturing, and business operations, highlighting the need for sustainable water management practices across industries.
