Packaged Wastewater Treatment Market Report 2026

The packaged wastewater treatment market size has grown rapidly in recent years. It will grow from $28.92 billion in 2025 to $32.4 billion in 2026 at a compound annual growth rate (CAGR) of 12%. The growth in the historic period can be attributed to rising environmental regulation enforcement, increasing wastewater generation, growth in industrial water discharge, rising municipal treatment demand, increasing awareness of water pollution control.

The packaged wastewater treatment market size is expected to see rapid growth in the next few years. It will grow to $51.21 billion in 2030 at a compound annual growth rate (CAGR) of 12.1%. The growth in the forecast period can be attributed to increasing investment in compact treatment facilities, rising need for sustainable water management, growing adoption of advanced filtration technologies, expansion of industrial treatment applications, increasing focus on decentralized wastewater solutions. Major trends in the forecast period include growing demand for compact wastewater treatment systems, increasing adoption of modular treatment technologies, rising preference for efficient pollutant removal solutions, increasing requirement for flexible wastewater infrastructure, growing focus on environmentally compliant water treatment solutions.

The rising levels of water pollution and the growing scarcity of clean water are expected to drive the expansion of the packaged wastewater treatment market in the coming years. Water pollution refers to the contamination of rivers, lakes, groundwater, or oceans by harmful substances that render water unsafe for living organisms, while clean water scarcity describes a condition in which there is an insufficient supply of safe and usable water to meet the needs of populations, agriculture, and ecosystems. Increasing water pollution and clean water shortages are largely driven by rapid population growth, which elevates demand for freshwater while simultaneously generating higher volumes of waste and wastewater that contaminate already limited water resources. Packaged wastewater treatment systems help address water pollution and clean water scarcity by treating and reusing wastewater at the local level, preventing pollutants from entering natural water bodies and increasing the availability of safe water for reuse. For example, in July 2025, according to the Environment Agency, a UK-based government department, serious pollution incidents in the region increased by 60% compared to 2023, underscoring persistently poor performance across all nine water and sewerage companies. Therefore, the escalating levels of water pollution and the shortage of clean water are contributing to the growth of the packaged wastewater treatment market.

Major companies in the packaged wastewater treatment market are focusing on product launches. For instance, Biogill, an Australia-based company specializing in biological wastewater treatment solutions, introduced its latest product series, the Max 2, 4, and 6, in July 2023. The MAX units feature modern materials and designs, ensuring improved durability, reliability, and efficiency. These units are designed for easy setup, use, and maintenance, resulting in reduced operational costs and downtime. The introduction of innovative products such as the MAX Units underscores Biogill's commitment to providing cost-effective wastewater treatment solutions globally.
