Sewage Treatment Facilities Market Report 2026

The sewage treatment facilities market size has grown strongly in recent years. It will grow from $271.74 billion in 2025 to $291.5 billion in 2026 at a compound annual growth rate (CAGR) of 7.3%. The growth in the historic period can be attributed to expansion of urban sewer networks, growth in industrial wastewater generation, early investments in municipal treatment facilities, rising public health standards, adoption of mechanical treatment processes.

The sewage treatment facilities market size is expected to see strong growth in the next few years. It will grow to $392.82 billion in 2030 at a compound annual growth rate (CAGR) of 7.7%. The growth in the forecast period can be attributed to increasing investments in smart water infrastructure, rising demand for water reuse and recycling, expansion of energy-neutral treatment facilities, growing integration of digital monitoring systems, stricter environmental discharge regulations. Major trends in the forecast period include increasing adoption of automated process control systems, expansion of advanced wastewater treatment technologies, growing focus on energy-efficient treatment solutions, increased deployment of decentralized treatment plants, enhanced emphasis on regulatory compliance.

The rising wastewater discharge is expected to drive the growth of the sewage treatment facilities market in the coming years. Wastewater, commonly referred to as sewage, is used water that contains impurities, toxins, and pollutants from domestic, agricultural, industrial, or commercial activities. Sewage treatment plants treat this wastewater before discharge, removing harmful contaminants and pollutants to protect public health and the environment. For instance, in March 2024, the Environment Agency (EA), a UK-based environmental regulator, reported that in 2023, the number of sewage spills rose to 464,056, a 54% increase from 301,091 spills in 2022. Therefore, the rising wastewater discharge is propelling the growth of the sewage treatment facilities market.

Major companies in the sewage treatment facilities market are concentrating on innovative solutions, including advanced water treatment facilities, to enhance efficiency, reduce operational costs, and improve environmental sustainability. Water treatment solutions encompass various processes and technologies aimed at improving water quality by eliminating contaminants, pathogens, and impurities from water sources. For example, in April 2024, Thermax Ltd., an India-based energy and environment solutions company, launched a comprehensive 5G network across all 18 islands of the Faroe Islands, achieving full population coverage in partnership with Ericsson. This rollout provides residents with fast, low-latency internet access, enhancing mobile broadband and call quality with features like fixed wireless access and voice over LTE (VoLTE). The deployment effectively addressed geographical challenges, including coverage on bridges, ferries, and fishing boats, and is expected to significantly benefit local industries such as fisheries and tourism by enabling advanced technologies like IoT and AI for improved operational efficiency and sustainability.
