Decentralized Water Treatment Market Report 2025

This report covers market characteristics, size and growth, segmentation, regional and country breakdowns, competitive landscape, market shares, trends and strategies for this market. It traces the market’s historic and forecast market growth by geography.

The decentralized water treatment market size has grown rapidly in recent years. It will grow from $17.68 billion in 2024 to $20.09 billion in 2025 at a compound annual growth rate (CAGR) of 13.6%. The growth in the historic period can be attributed to increasing awareness of the benefits of clean water, the growing number of shopping malls and hotels and deteriorating water quality in countries, dwt is beneficial for communities considering new systems, rising need for a de-centralized wastewater treatment, the rising understanding of the necessity for clean water.

The decentralized water treatment market size is expected to see rapid growth in the next few years. It will grow to $33.75 billion in 2029 at a compound annual growth rate (CAGR) of 13.8%. The growth in the forecast period can be attributed to rising demand for freshwater, increase the penetration rate of decentralized water treatment, rapid development of the economy, increasing population and rapid urbanization, rise consumer awareness. Major trends in the forecast period include adoption of blockchain technology, increasing adoption of decentralized water treatment, integration of IoT and AI, rise of decentralized water treatment as a service (DTaaS), rising innovations.

The increasing demand for freshwater is expected to drive the growth of the decentralized water treatment market. This demand is rising due to factors such as population growth, urbanization, industrialization, agricultural expansion, climate change, environmental degradation, and inefficient water usage. Decentralized water treatment systems help meet the demand for freshwater by offering localized purification solutions, alleviating pressure on centralized systems, and improving access to clean water in remote or underserved regions. For example, in October 2023, the Australian Bureau of Statistics reported that from 2021 to 2022, Australia’s total water consumption reached 13,449 GL, with self-extracted water use rising by 3% to 66,205 GL. As a result, the growing demand for freshwater is fueling the expansion of the decentralized water treatment market.

Leading companies in the decentralized water treatment market are advancing innovative technologies, such as mobile water treatment units, to improve wastewater reuse at reduced costs. A mobile water treatment unit is a portable system designed to treat and purify water on-site, making it suitable for drinking, industrial purposes, or environmental applications in remote or emergency situations. For example, in May 2024, Nijhuis Saur Industries, a water technology company based in the Netherlands, introduced the Grey Water Treatment 2 solution. This decentralized water management system allows industries and municipalities to locally treat grey water - such as rainwater, surface water, and shower water - for reuse in applications like toilet flushing and irrigation. The system promotes circular water management by converting typically wasted water into a valuable resource. Designed for efficiency, the unit operates in a single shift, offering rapid access to treated water and significantly reducing the demand for freshwater by at least 30%.

In January 2024, Saur, a France-based company specializing in water and leisure management, acquired Natural Systems Utilities (NSU) for an undisclosed amount. The acquisition is aimed at leveraging the strengths of both companies to foster new synergies and support the commercial and residential building markets in the Americas and Europe. The acquisition is expected to expand Saur's water reclamation and reuse activities. Natural Systems Utilities (NSU) is a US-based company providing environmental water treatment services, fully integrated water supply, wastewater treatment, and management for various entities.

The decentralized water treatment market consists of revenues earned by entities by providing services such as water purification, water recycling and reuse, community water systems, and consulting and technical services. The market value includes the value of related goods sold by the service provider or included within the service offering. The decentralized water treatment market also includes sales of point-of-use filters, UV disinfection systems, reverse osmosis systems, water softeners, chemical disinfection systems, drip irrigation systems, and rainwater harvesting systems. Values in this market are ‘factory gate’ values, that is the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

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).

Decentralized water treatment involves placing water or wastewater treatment facilities closer to the water supply or demand point rather than centralizing them in distant treatment plants. This approach aims to offer more localized and efficient treatment solutions, resulting in cost reduction, enhanced flexibility, improved sustainability, and increased control over water management.

The main technologies of decentralized water treatment are membrane technology, thermal technology, and others. Membrane technology refers to the use of membranes to filter and purify water at a local or smaller scale, typically for individual buildings, communities, or remote locations. Point of use (POU), point of entry (POE), and small-scale systems are used for wastewater treatment, effluent treatment, and water treatment applications by municipal and industrial end users.
