Market Trends and Insights

Stricter zero-liquid-discharge (ZLD) mandates

The 2015 zero-liquid-discharge direction provides a standing compliance base for affected distilleries. India’s Central Pollution Control Board issued its December 7, 2015, direction to State Pollution Control Boards to ensure zero-liquid discharge at Ganga basin molasses-based distilleries. It included yeast manufacturing units and specified implementation through either of 2 treatment routes. The route choice leaves room for competing configurations while preserving the same compliance objective. Distillery compliance depends on the complete treatment route, making the fit between each component and the chosen treatment configuration commercially decisive.

Growth in decentralized modular treatment plants

For island municipalities, modular treatment offers a way to add local drinking-water capacity. The Municipal Government of El Nido inaugurated Palawan’s first modular water treatment plant on November 28, 2025. The Singapore Water Association reported in December 2025 that the 3-million-liter-per-day facility supplied potable water to more than 50,000 residents and tourists. Its report described pressure from climate variability, water scarcity and rising demand in the island municipality. Delivering potable capacity in that setting makes decentralized units relevant to a supply shortage, giving the municipal buyer a concrete reason to invest in treatment.

Rising industrial reuse quotas in water-stressed regions

Industrial reuse targets create treatment demand where users can obtain recycled water for suitable production uses. Zhengzhou’s July 7, 2025, plan set year-end industrial recycled-water-use targets of at least 15% in 2025, 20% in 2026 and 30% in 2027. These targets covered eligible uses within distribution-network coverage in the central urban area, excluding Zhengzhou Airport Economy Zone. That conditional scope makes connection availability central to the commercial opportunity for treatment suppliers. A higher target can strengthen demand for usable recycled water without creating the same opportunity at every industrial site. Network-connected industrial sites offer suppliers a defined route to reuse sales, with eligible production uses setting the treatment requirement.

Surge in capex for shale-based produced-water reuse

Rising reuse volumes can translate into investment beyond the treatment unit, including the infrastructure that moves and stores produced water. Select Water Solutions recycled 332 million barrels of produced water across its fixed facilities and mobile solutions in 2025, up 18% from 2024. In August 2026, Select Water Solutions agreed to add 60,000 barrels per day of produced-water recycling capacity in Eddy County, New Mexico, through a contract-backed Northern Delaware Basin expansion.^[1] The broader project included pipelines and storage, with an expected cost of approximately USD 100 million to USD 120 million and operation by the end of 2027. The commitment places investment ahead of additional throughput, while the combined scope gives infrastructure providers work beyond treatment units.

High total cost of ownership for advanced membranes

Membrane bioreactor economics depend on the process conditions needed to maintain treatment, as well as the equipment purchase. A 2026 review reported higher operating costs and energy use for membrane bioreactors than conventional activated sludge, primarily because of aeration requirements and membrane fouling.^[2] It reported operating-cost ranges of USD 0.09 to USD 0.45 per cubic meter for membrane bioreactors, against USD 0.02 to USD 0.4 for conventional activated sludge. Energy consumption ranged from 0.4 to 1.15 kilowatt-hours per cubic meter for membrane bioreactors, against 0.3 to 0.64 for conventional activated sludge. The commercial hurdle is to justify that continuing burden against the site’s treatment requirement, leaving suppliers with a cost-based constraint that an attractive initial equipment price alone cannot resolve.

Limited Operation and Maintenance skill base in emerging economies

Plant modernization depends on having enough qualified personnel to operate the added treatment capability. At its June 9, 2026, briefing, South Africa’s Portfolio Committee on Water and Sanitation reported that 1,151 of 2,431 required wastewater process controllers were employed nationally. It also reported a shortage of 84 supervisors and said skilled-personnel shortages directly affected system functionality and operating efficiency. That combination creates an operating constraint at both process-control and supervisory levels, making equipment additions an incomplete response to deficient treatment capability. Utilities must spend time and money building operating coverage before added treatment complexity can be run reliably.

Water And Wastewater Treatment Technologies Market Segment Analysis

Dissolved solids removal accounted for a 31.1% share of the water and wastewater treatment technologies market size in 2026. The largest segment includes desalination, where Veolia builds and operates plants. In July 2026, Veolia reported that it accounted for 18% of global installed desalination capacity. It also reported that it produced 13 million cubic meters of desalinated water per day worldwide and accounted for 19% of desalination capacity in the Middle East. This combination of plant construction and daily water production gives desalination suppliers a service role extending beyond the initial equipment sale.

Biological treatment/nutrient and metals recovery is forecast to be the fastest-growing segment, with a CAGR of 6.9% during 2027-2032. Charlotte City Council approved a USD 30.34 million guaranteed maximum price for MEB General Contractors to construct McAlpine Creek’s nutrient-harvesting facility on April 28, 2025. By August 20, 2026, the project team had set its approximately 50,000-pound reactor on support columns, with further facility construction proceeding. The project was intended to recover nutrients and produce a marketable fertilizer, adding a resource-recovery function to wastewater treatment. Its commercial scope includes building a product-producing facility, which makes plant integration as relevant to the buyer as the recovery vessel itself.

Municipal water and wastewater treatment represented a 57.59% water and wastewater treatment technologies market share in 2026. Fort Worth’s Eagle Mountain drinking-water plant had 105 million gallons per day of capacity in July 2025, against projected demand of 140 million gallons per day by 2028. The city’s 35-million-gallon-per-day expansion, under construction in 2026, includes ozone treatment, biological filtration, membrane filtration and disinfection. Municipal buyers can bring several process technologies into one capacity project, creating work across more than one equipment category. Added capacity of 35 million gallons per day equals the difference between the plant’s existing capacity and its projected 2028 demand.

Food and beverage is forecast to be the fastest-growing segment, with a CAGR of 7.4% during 2027-2032. In February 2025, Veolia Water Technologies was selected for Omer Vander Ghinste Brewery’s expansion near Kortrijk, Belgium, designed around membrane bioreactor, anaerobic and high-recovery reverse-osmosis systems. The design specified biogas for heating water and buildings, and recycled brewing water for cooling, bottle washing and vessel cleaning. A brewery weighing this configuration has to value the recovered water and biogas alongside the effluent-treatment capacity.

Geography Analysis

Asia-Pacific Water And Wastewater Treatment Technologies Market

Asia-Pacific held a 35.34% water and wastewater treatment technologies market share in 2026 and is forecast to be the fastest-growing geography, with a CAGR of 8.25% during 2027-2032. In July 2026, the Bangalore Water Supply and Sewerage Board awarded WABAG work to design, build and operate 100-million-liter-per-day sewage and 25-million-liter-per-day tertiary plants at Byramangala, India. The awards also covered a 60-million-liter-per-day sewage plant at Bellandur. The Asian Development Bank estimated in May 2025 that around 80% of wastewater in Asia and the Pacific was untreated, leaving a large unmet treatment requirement behind municipal awards of this kind. WABAG’s design-build-operate role links the municipal capacity award to service responsibility after construction, extending the contractor’s scope beyond commissioning.

North America shows a municipal upgrade requirement in Toronto, where the city awarded GHD Limited engineering and construction services for Humber Treatment Plant’s North Plant secondary-treatment upgrades on August 20, 2025. The award specified a contract term through December 31, 2034. Europe also has a substantial wastewater investment channel, with wastewater-treatment projects accounting for 37.7% of total EU environmental protection investment in 2025.^[3] Toronto illustrates a long delivery horizon for a defined secondary-treatment upgrade, while the EU investment mix makes wastewater a priority for contractors seeking environmental infrastructure work.

South America has a project-procurement route illustrated by Cesan’s June 2025 auction in Espírito Santo, Brazil. It selected the GS Inima and Forte Ambiental consortium for one lot and Acciona for the other, covering sewage collection and treatment across 43 municipalities. In Middle-East and Africa, South African officials commissioned Mpophomeni’s wastewater works on July 18, 2025, designed for Department of Water and Sanitation effluent standards and incorporating a treated-effluent pipeline and wetland rehabilitation. By October 2025, Egypt’s Ministry of International Cooperation described the Bahr El-Baqar system as implemented to treat and transfer wastewater for land reclamation in the Sinai Peninsula. Treatment here is tied either to specified collection services or to a downstream water use, so the delivery interface becomes part of the supplier’s commercial scope.

Regulatory Framework and Outlook

The comparison covers selected jurisdictions from the perspective of plant operators choosing water and wastewater treatment technologies. The United States column covers industrial-stormwater permittees in EPA-administered areas, while China’s column covers municipal discharge controls. Germany’s contaminant-dependent discharge charges and South Africa’s capacity-based connection conditions place additional operating decisions around the treatment technology. Selected treatment functions have to align with the discharge authorization or service-capacity requirement that governs how the plant can serve its users.

The US ratings reflect permit continuity for prior covered operators in August 2026, following EPA’s earlier proposed renewal, preserving an established compliance basis. China’s ratings reflect defined municipal requirements with additional controls under its amendment, effective March 1, 2026. Germany’s ratings balance the contaminant-charge framework with expanded EU duties and national transposition due July 31, 2027. South Africa’s conditional route is balanced by capacity controls and a proposed October 2025 bill on registration and licensing, making operator eligibility an additional commercial consideration.

Value Chain Stages

The value chain compares how engineering, treatment equipment and plant services turn a process requirement into operating capability. DuPont Water Solutions makes FilmTec reverse-osmosis elements containing spiral-wound thin-film composite polyamide membranes, while AECOM provides studies, design and project-delivery services for water-treatment facilities. These distinct roles place supplier earnings both in the physical treatment components and in the work required to incorporate them into a functioning plant.

WABAG manages existing water and wastewater plants through service agreements, creating an earnings route that extends beyond equipment delivery. That model makes operating responsibility commercially distinct from owning or manufacturing a treatment component. Veolia Water Technologies combines design, build, operation and upgrade services, providing an organizational route for connecting those responsibilities. Contracts that keep project delivery and plant operation with one supplier give that supplier a route to retain value, provided the interfaces between the two stages are managed.

Key Opportunities for Market Participants

The comparison centers on EU wastewater-treatment duties and a New Zealand plant procurement. The revised EU wastewater directive, in force since January 2025, requires countries to collect and treat wastewater in urban areas with more than 1,000 inhabitants. Its extended producer responsibility scheme requires pharmaceuticals and cosmetics industries to pay at least 80% of micropollutant removal costs. Implementation deadlines vary by duty, making the relevant plant’s scope and timing central to the commercial opening.

Christchurch City Council’s polymer-plant procurement combines design and construction within one buyer requirement. The EU duties create a broader opening for plant-level treatment packages, with each package scoped to the applicable coverage or micropollutant requirement. Producer sectors carry at least 80% of micropollutant removal costs under the EU scheme, making treatment selection and cost allocation a joint commercial decision. Suppliers able to scope packages for both plant operators and responsible producer sectors can address the treatment requirement alongside its funding arrangement.
