GLOBAL WATER TREATMENT INDUSTRY-GROWTH DRIVERS AND CHALLENGES
- Water treatment involves processes, technologies, devices, and chemicals that help deliver clean water to an end-user.
- The water treatment market includes three key segments. Point-of-entry treatments and technologies are those installed at entry to a commercial or residential water source, reducing contaminants to the full building. Point-of-use treatments and technologies are installed at a single point, the final barrier prior to the use of water. Wastewater treatment systems are facilities that treat water for reuse or for discharge to the community.
- The global point-of-use water treatments market was estimated at $19.9 billion in 2018, with a 10.5% annual growth rate projected through 2026. The global point-of-entry water treatment market was estimated at $7.8 billion in 2019, with an annual projected growth rate of 4.1% through 2027.
- The global market for technologies used in wastewater treatment facilities was estimated at $64.4 billion in 2018, projected to increase at an annual rate of 5.2% through 2023.
Increasing Water Pollution
- Increasing water pollution globally has been identified as a key factor driving growth in the global water treatment industry. Industrialization, wastewater disposal, and the resultant growing contamination of water sources are projected to continue to drive growth for the water treatment systems market through at least 2024.
- Pollutants are the major cause of the degradation in water supplies globally. Water pollution is on the rise, and contaminated water sickens approximately 1 billion people globally each year.
- Contaminants found in the water supply, such as phosphorous, nitrogen, microbial pathogens, pesticides, and oxygen-consuming materials, degrade the quality of water supplies, making it unsuitable for end use. A 10-15% increase in nitrogen loads in river ecosystems is projected over the next 30 years.
- In developing countries, 80% of sewage is discharged without being treated, leading to further contamination of lakes and rivers.
- Water treatment systems filter and disinfect disease-causing contaminants, and point-of-use and point-of-entry technologies, such as reverse osmosis and ion exchange, provide barriers to contaminants in the water supply.
- Technological advancements in the water treatment industry are a key growth driver for this market.
- Technologies designed to improve the water supply are numerous and continually evolving. Advancements in processes, such as modular equipment design and membrane filtration technologies, support contaminant removal processes, making them safer and less expensive to implement. The efficiency of one such process, reverse osmosis, which removes chemicals, metals, and salts, from the water supply, has improved greatly due to the implementation of these new technologies.
- Reverse osmosis owns the largest share of point-of-use water treatment technologies segment, due to its ability to dissolve 99% of feed water contaminants, as well as remove contaminants, such as nitrates, pesticides, fluoride, arsenic, and chlorine.
- Other growing technologies, such as those used to support ozone treatment, reduce the need to use harsh chemicals for treating water.
- Technological innovations are a key contributor to industry growth through 2024, and reverse osmosis technologies are expected to maintain their share during this time frame.
Energy Consumption of Treatment Facilities
- High energy consumption is a challenge facing the water treatment industry. Wastewater filtration in the US uses 3% to 15% of the nation's power. Without energy-efficiency improvements, costs for water treatment processes will remain high.
- Smaller plants, and those whose specific function is to remove nutrients, require more power. Improving energy efficiency, through advanced power systems, could provide cost savings of up to 50%. A study of 23 water treatment facilities in Germany and Switzerland showed that power consumption could be reduced about 67% with appropriate actions.
- In municipal water treatment, biological processes (which require bacteria and other organisms to break down waste) are responsible for the most energy consumption. Several solutions that help reduce the energy demand associated with these processes include membrane technology (which uses 90% less energy) and more direct treatment of water being returned for contaminant elimination.
- Performing an energy audit and considering more sustainable energy sources, such as solar, wind, or geothermal energy, are other ways to reduce energy use in water treatment facilities.
Water Treatment Installation and Operating Costs
- High installation and operating costs impact wastewater treatment facilities, and, to a lesser extent, the point-of-entry segment of the water treatment market.
- Wastewater treatment facilities are equipped with instrumentation and programmable logic controllers (PLC), which automate processes, but have associated high operational costs. Additionally, the more contaminants present in the water supply, the greater the number of steps in the treatment process, which also drives up cost. Depending on the complexity of the treatment process, pre-treatments may also be required, yet another cost associated with the treatment of wastewater.
- Installation costs can also be significant. Industrial water treatment systems cost between $45,000 for a simple system, to over $10 million for a high-end, high-capacity system.
- Point-of-entry water treatment systems, especially those that use reverse osmosis technology, typically have somewhat high installation costs, though they last for 5-7 years. Point-of-use water treatment systems are generally quite cost effective, though filters may need to be changed every 3-6 months.
- The price of a point-of-entry water system ranges from $400 to upwards of $10,000. Point-of-use systems, such as water filters or water distillers, start at under $100 for a filter, to $1,500 for a higher-end water distiller.
GLOBAL WATER TESTING AND ANALYSIS INDUSTRY-GROWTH DRIVERS AND CHALLENGES
- Water quality testing and analysis includes systems and technologies used to monitor and optimize water quality, measuring factors such as temperature and pollutant levels, including pH, nitrates, phosphates, and other hazardous contaminants.

- The global water quality and testing market was estimated at roughly $3.4 billion in 2018, with growth rates ranging from 5.0% to 7.3% CAGR through 2025.
Population Growth and Industrialization
- Population growth and industrialization have resulted in contaminated water supplies and rising pollution. Increasing levels of contamination have driven demand for water testing and analysis in the residential, commercial, and industrial sectors.
- As the global population grows, there is an increasing need to manage commercial development and water resources. Fifteen percent of the world's population lives in an area in which demand for fresh water exceeds supply, due to overpopulation.
- Pollutants from industrial sources include lead, nitrates, phosphates, asbestos, and petrochemicals. These can be harmful for drinking water, as well as for marine life. Industrial pollution is often caused by inefficient waste disposal, with radioactive waste, sludge, and harmful chemicals being dumped into oceans and rivers.
- Water testing is considered critical for government organizations looking to understand the contaminant levels in the water supply, and safeguard the public from environmental and health risks of contamination. Water testing is also important for individuals, to ensure their water is safe from pollutants.
- Given the significant issues of industrial pollution, and the need for clean, safe water caused by population growth, water testing and analysis will continue to be important to help deliver safe, clean, water for the world's population.
Government Initiatives To Protect Water Supply
- With projections of deteriorating water quality globally, governments around the world have been working to avoid water contamination and water shortages. Demand for water testing has resulted from strict regulations implemented by government organizations to preserve the quality of the water supply.
- The United States government implemented the Clean Water Act (CWA), which regulates surface water quality standards and establishes a structure for the discharge of pollutants into waters. They also instituted the Safe Drinking Water Act (SDWA), a standards-based set of regulations designed to ensure safety of the US water supply.
- The Clean Water Act had a number of positive effects, including driving awareness of the problem of water pollution, and increasing the number of safe water bodies in the US by two-thirds.
- India and China are regulating the use of water in various food, beverage, and pharmaceutical products, requesting water be tested within their facilities. As consumers in India become more aware of the importance of safe water, they expect the water supply to meet standards.
- In 2010, the United Nations recognized the right of every person to have enough water to meet their needs, and to be safe, accessible, and affordable.
- As governments continue to be involved in testing water supplies, setting standards for clean, safe, water, and seeing measurable results, the water testing industry will continue to be positively impacted.
