Market Overview

The water and wastewater treatment technologies market size was estimated at USD 50.56 billion in 2020, and the market is projected to register a CAGR of over 7% during the forecast period (2021-2026).

The market was negatively impacted by COVID-19 in 2020. The outbreak of coronavirus has resulted in the halting of operation in water and wastewater treatment facilities and caused the delay in the construction of new water and wastewater treatment facilities. In the global chemical industry, the manufacturing operations of major companies have been scaled down to 40%-60% capacity due to labor shortages and disruptions in the supply of raw material. According to the American Chemistry Council, Europe, North America, and Asia-Pacific registered a production drop of around 3.1%, 2.3%, and 1%, respectively, during April-May 2020. Globally, around 4% of the new construction projects of water and wastewater treatment facilities are canceled, which has impacted the market for water and wastewater treatment technologies.

  • Over the short term, one of the major driving factors of the market is the rapidly diminishing freshwater resources across the world. Increasing demand from shale gas exploration activities, along with growing wastewater complexities in developing economies, is likely to boost the market growth.
  • However, a lack of awareness on optimum utilization of water treatment techniques is likely to restrain the market.
  • Active research on water treatment technologies may provide opportunities for market growth in the future.
  • Middle-East and Africa is likely to witness the highest growth rate during the forecast period.

Key Market Trends

Municipal Water and Wastewater Treatment to Dominate the Market

  • Wastewater treatment is necessary and used across the world, in different cities. The major applications of treatment technologies include preliminary treatment, primary and secondary treatment, tertiary treatment, biological nutrient removal (BNR), resource recovery, energy generation, etc.
  • Moreover, municipal wastewater treatment involves a lot of biomass. Therefore, biological treatment is a major step used for the treatment of biowaste.
  • The global water consumption rate has been increasing by 100% every twenty years. The rising scarcity of potable water, coupled with the growing population and increasing water demand, is the major concern that has been driving the demand in the market studied.
  • North America and Europe are adopting the latest technologies in wastewater treatment at a faster rate than in other regions. The developed regions of North America and Europe are expected to continue the momentum of adaptation of the latest technologies.
  • The United States is one of the highest consumers of water in the world, with 160 gallons of per capita consumption. Around 80% of the US water and wastewater treatment industry is owned and managed publicly. Mexico holds more than 1500 wastewater treatment plants.
  • In the United States, approximately 19% of the population are dependent on septic tanks to treat and dispose of wastewater. Around 14,748 publicly owned treatment works are providing wastewater collection, treatment, and disposal services to approximately 238 million residents in the country.
  • In the Asia-Pacific region, China, India, and ASEAN countries are likely to witness significant demand due to an increase in urbanization. In its 13th Five-Year Plan, China announced an investment of USD 48 billion for urban wastewater treatment. With municipal wastewater being the largest source of urban wastewater generated, the demand for water treatment technologies is expected to increase rapidly.
  • The majority of drinking water used in Israel and Saudi Arabia is generated from the desalination process, which is likely to boost the demand for municipal water and wastewater treatment technologies. With an ambitious goal of achieving 100% usage of treated wastewater by 2025, Saudi Arabia is expected to become the third-largest water reclamation and reuse market across the world. Currently, Saudi Arabia’s municipal wastewater treatment and reuse sector is valued at over USD 4.5 billion.
  • With an estimated USD 23 billion investment in wastewater treatment and reuse-related capital improvement projects over the next 20 years, the demand for the market studied is expected to through the forecast period. Hence, the municipal water and wastewater treatment industry is likely to dominate the market during the forecast period.
Water and Wastewater Treatment Technologies Market Key Trends

Asia-Pacific to Dominate the Market

  • Asia-Pacific accounted for the major share of the water and wastewater treatment technologies market, owing to high demand from countries like China and Japan.
  • China has been discharging more wastewater than industrial wastewater in recent times. Adding to the issue is the huge problem of pollution, especially in the major industrial locations of the country.
  • Hence, the Chinese government began to concentrate more on the reorganization of the pollutant treatment measures, including water and industrial wastewater treatments, which majorly include biological treatment that comprises aerobic treatment, anaerobic treatment, etc.
  • According to the Ministry of Housing and Urban-Rural Development, the number of wastewater treatment plants in China increased to about 3700 plants in 2016, with a total treatment capacity of roughly 150 million m3/d. The sludge production was 6.25 million tons of dry solids/y in 2013 and increased to approximately seven million tons of dry solids/y in 2016. It is estimated that the sludge production will amount to 10 million tons of dry solids/y in 2020. Proper sludge treatment and disposal have been far behind the increase in wastewater treatment capacity due to relatively much less investment for sludge facilities and increasingly limited space for sludge landfills as one of the traditional disposal routes.
  • There are numerous chemical plants lined up for construction within the period of the next five years in the country. For instance, in November 2019, BASF started the construction of its USD 10 billion integrated petrochemicals project, located in the southern province of Guangdong in China. The plant is planned to produce engineering plastics, thermoplastic polyurethane (TPU), and other petrochemical products used in industries like automotive, electronics, and new energy vehicles.
  • On average, the water consumption rate is increasing by 100% every twenty years. The rising scarcity of potable water, the growing population, and increasing water demand are the major concerns that are driving the water and wastewater treatment technologies during the forecast period.
  • In India, water purification is expected to register a decent increase during the forecast period, owing to various government initiatives. The Council on Energy, Environment & Water (CEEW), in association with the 2030 Water Resources Group, is planning to improve wastewater management in India, along with increasing private investments to build wastewater treatment plants.
  • The government is taking measures to boost the investment in its food processing industry. The government sanctioned about 39 Mega Food Parks (MFPs) to set up in the country under the Mega Food Park scheme. Among these, only 18 MFPs became operational, while the others are under development. The food processing industry is expected to potentially attract an investment of around USD 33 billion by 2024. This is also expected to drive the demand in the food processing industry and create future opportunities for the market studied in the country.
  • The food and beverage industry of South Korea is one of the largest in the region, supported by the surge in organic food processing. It is estimated to be valued at USD 9,983 million in 2020, which is expected to increase by 2024 and reach USD 13,646 million, at an 8.1% growth rate during the forecast period. This growth is expected to be attributed to the increase in the demand for membrane filtration in the country.
  • Hence, Asia-Pacific is likely to dominate the market during the forecast period.
