Water and Sewage Market Report 2025

The water and sewage market size has grown strongly in recent years. It will grow from $737.03 billion in 2024 to $797.39 billion in 2025 at a compound annual growth rate (CAGR) of 8.2%. The growth in the historic period can be attributed to increase in regulations of government for wastewater treatment, rapid urbanization, growing wastewater complexities, increased demand for water from agricultural sector, increased demand for steam and air-conditioning supply, and emerging markets growth.

The water and sewage market size is expected to see strong growth in the next few years. It will grow to $1.03 trillion in 2029 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to the rise in global population, rapidly diminishing freshwater resources, increasing demand for wastewater treatment, industrial pollutions, awareness on cleanliness and increasing smart cities will drive growth. Major trends in the forecast period include investing in the development of technologies, developing or adopting drip irrigation systems, deploying artificial intelligence in the wastewater and sewage treatment, implementing of IoT based smart irrigation systems, developing of energy efficient and ecofriendly products and attracting government investments.

The significant volume of untreated wastewater is expected to drive growth in the water and sewage market. Wastewater, which is used water generated from residential and commercial sources, contains nitrogen and phosphorus from human waste, food, and certain soaps and detergents. This water must be treated in sewage treatment facilities to reduce pollutants to levels that nature can tolerate, thereby increasing the demand for such facilities. For instance, in August 2024, United Nations Water, a Switzerland-based interagency mechanism coordinating efforts of UN entities and international organizations on water and sanitation, reported that in 2022, 42% of domestic wastewater worldwide was not adequately treated before being discharged. This resulted in an estimated 113 billion cubic meters of household wastewater being released into the environment without sufficient treatment. Consequently, the large amount of untreated wastewater is expected to propel the growth of the water and sewage market in the future.

Growing industrialization is also anticipated to boost the water and sewage markets moving forward. Industrialization signifies a major societal and economic transition from agrarian to industrial societies, marking a significant transformation. Water and sewage systems are essential for supporting industrial processes and ensuring proper wastewater disposal, thereby contributing to environmental sustainability and industrial efficiency. For example, in June 2024, the Federal Reserve Board, a U.S.-based governing body of the Federal Reserve System, noted that industrial capacity increased by 1% in 2022 and 2.3% in 2023, with an anticipated growth of 1.2% in 2024. Therefore, the ongoing industrialization is a driving force behind the water and sewage market.

Conventional wastewater treatment plants are adopting advanced technologies to address micropollutants. Micropollutants, originating from pharmaceutical residues, household chemicals, personal care products, and pesticides, are effectively treated using technologies such as moving bed biofilm reactors (MBBR), ozone-based advanced oxidation, adsorption, and powdered activated carbon (PAC). European countries, such as Germany and Switzerland, are placing a growing emphasis on removing micropollutants from wastewater streams. In Germany, cost-effective technologies such as GE’s membrane bioreactor and powdered activated carbon technology are employed for this purpose. Major companies at the forefront of using advanced technologies to treat micropollutants include Suez Group, Arvia, and Novartis.

The water and sewage market includes revenues earned by entities by domestic sewage, industrial sewage, storm sewage, treated sewage, and untreated sewage. The market value includes the value of related goods sold by the service provider or included within the service offering. Only goods and services traded between entities or sold to end consumers are included.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD, unless otherwise specified).

Water and sewage involve waste materials such as faces or contaminated water from homes and factories, which are carried away through sewers. Wastewater, the polluted form of water resulting from rainwater runoff and human activities, undergoes a treatment process that encompasses multiple stages to eliminate harmful bacteria, pollutants, and contaminants.

The primary types of water and sewage infrastructure include water supply and irrigation systems, sewage treatment facilities, and steam and air-conditioning supply systems. Sewage treatment is a wastewater treatment process aimed at removing impurities from sewage to produce an effluent suitable for disposal into the environment or for reuse, thereby preventing water pollution from raw sewage discharges. Operators in this domain can be categorized as public or private, and these systems serve various sectors such as residential, commercial, industrial, and agriculture.
