WATEX Tehran Water & Wastewater Exhibition 2027

24–27 January 2027
Tehran International Permanent Fairground, Tehran, Iran

WATEX is the international trade fair for water and wastewater infrastructure and technology. Its scope connects water and wastewater treatment, filtration and desalination with pumps, pipelines, irrigation, measurement, automation and conservation equipment. It is more than a display of products: utility teams, project developers, engineers, consultants and suppliers can use the exhibition to compare solutions, test technical fit and identify questions for procurement, deployment and service.

WATEX at a glance

The organiser’s accessible event website describes the 21st edition in 2025; information for the 2027 programme and participation arrangements may be released separately.

Why WATEX matters to water professionals

Compare connected parts of the water cycle

Water infrastructure decisions are interdependent. Treatment plants rely on suitable pumps, valves, controls, meters and pipe networks; irrigation and wastewater reuse also depend on equipment matching water quality and intended use. WATEX brings these product families into one professional setting, giving visitors a chance to compare interfaces and specifications across systems rather than assessing a single component in isolation.

Evaluate options against operating needs

Utility and project teams can organise a visit around practical questions: required flow and pressure, water quality, treatment performance, energy use, measurement accuracy, maintenance access, spare parts and service arrangements. These checks help distinguish a technically promising product from one that is suitable for a particular site or operating environment.

Explore suppliers and partnerships

Manufacturers, contractors, consultants, distributors and project developers can use the exhibition to introduce their capabilities and discuss potential applications. Conversations are most useful when visitors bring a defined project or sourcing brief and record the technical evidence and follow-up needed for each supplier.

Job roles to consider

Earlier organiser material names engineers and consultants, project developers, policy makers, technical and safety managers, regulatory bodies and research-and-development personnel. Procurement and operations teams whose remit matches the exhibition sectors may also find the product comparisons relevant.

Why visit WATEX?

1. Compare water and wastewater treatment, filtration and desalination options against a defined process or project requirement.
2. Evaluate pumps, valves, pipe systems and coatings together, including compatibility, operating conditions and maintenance.
3. Review meters, instrumentation, automation and leak-detection equipment for monitoring and system-control needs.
4. Explore irrigation, drainage and water-efficiency products relevant to projects where water use must be managed carefully.
5. Identify suppliers or technical partners to investigate further, then request specifications, references and service details after the exhibition.

Why exhibit at WATEX?

WATEX is relevant to manufacturers and service providers across water treatment, wastewater management, pumps, pipes, irrigation, measurement and conservation. Exhibitors may use the event to demonstrate technical capabilities, introduce products, discuss applications with engineers and project teams, and explore distributor or service relationships. These are opportunities to investigate, not guaranteed commercial outcomes.

Prepare a concise product brief that states operating range, materials, certifications, installation conditions, maintenance needs and local support. For imported goods, check whether the product falls under Iran’s mandatory standards and whether a Certificate of Conformity is required; applicability is product-specific. Confirm current market-access, payment, import and service requirements before finalising participation or a sale.

How to prepare before WATEX

1. Define the technical purpose of your visit

Write down the system or decision you need to address: treatment capacity, filtration, pumping, pipeline renewal, irrigation, water measurement, leakage, or industrial water use. Set a short list of must-answer questions and the specifications you can share.

2. Build a product and supplier comparison sheet

Use consistent fields for each conversation: product and application; flow, pressure or water-quality range where relevant; materials; energy and consumables; installation requirements; maintenance interval; spare parts; warranty and service; certifications; price and delivery details to request later. Do not compare products on headline capacity alone.

3. Prioritise meetings

Rank targets as A—essential to a current project, B—useful alternatives or partners, and C—worth exploring if time allows. The current edition’s exhibitor list and hall plan should be checked when available; the organiser’s website has provided participant and hall information for earlier editions.

4. Prepare focused questions

• Which design flow, pressure and water-quality range does the equipment support?
• What are the limits on feed-water variation, solids or chemical conditions?
• Which materials contact water or wastewater, and what service life is expected?
• What are the energy, chemical and replacement-consumable requirements?
• How are performance and measurement accuracy tested?
• What maintenance access, spare parts and local technical support are needed?
• Which installation, commissioning and operator-training tasks are included?
• Which conformity documents or product standards apply to the intended use?

How to make the most of the exhibition

Capture each discussion in a simple record: Company → Product → Application → Evidence → Next action. For example, note a pump’s duty point, efficiency data, materials, service arrangements and the project condition it may fit. Photograph or record technical information only with permission. Separate confirmed specifications from claims that still need documentation.

At the end of each day, group contacts by immediate project relevance, potential supplier or distributor fit, and general market intelligence. Send a specific follow-up request for drawings, performance curves, conformity documents, references or a technical meeting instead of a generic message.

WATEX visitor profile and business opportunities

Plan your time at WATEX

The listed 2027 dates span four exhibition days, with visitor hours shown as 08:00–15:00. If you have one day, prioritise meetings tied to a live project and the most critical product interfaces. With more time, reserve separate blocks for treatment and reuse; pumping, pipes and valves; and monitoring, irrigation and efficiency. These are planning suggestions, not an official hall schedule; confirm the final programme and access arrangements before travelling.

After WATEX: turn comparisons into decisions

Sort contacts into three groups: A—solutions that may address a current requirement; B—possible alternatives, suppliers or partners; C—useful market and technology information. Follow up with the exact evidence needed to compare technical fit: specifications, performance data, materials, conformity documents, installation requirements, operating costs, spare-parts availability and service terms. Record who will review each response and by when. A supplier conversation is a starting point for due diligence, not a substitute for it.

Is WATEX worth visiting?

WATEX is most relevant to professionals working with water and wastewater treatment, pipelines, pumps, irrigation, monitoring or water efficiency. Its cross-sector equipment scope can help utility teams, project professionals and industrial buyers compare related technologies, while suppliers can explain applications to an industry audience. The value of a visit depends on bringing a clear technical or sourcing objective and following up with documented specifications, service details and compliance checks.

Make your WATEX visit purposeful

Before you attend, ask: Which water-system decision, technical comparison or supplier question do I need to move forward? Define it, gather comparable evidence, and decide what follow-up will turn useful conversations into a next step.

Specify. Compare. Verify. Follow up.

Water and wastewater opportunities in Iran

Market size and demand indicators

A 2024 peer-reviewed review of water reuse in Iran cites estimates from 2023 research of about 103.5 billion cubic metres in annual water withdrawals against roughly 31 billion cubic metres of available renewable water. These are water-resource indicators, not market revenue or equipment imports; the review links the pressure to water reuse, treatment and efficiency needs.

Drivers and areas to investigate

The review identifies water scarcity, wastewater treatment and reuse, agricultural water demand and infrastructure needs as relevant issues. It discusses several possible areas for investigation: municipal wastewater treatment and reuse; treatment and managed reuse of agricultural drainage water; industrial wastewater reuse; and measurement or leakage-reduction solutions. The cited evidence does not establish current purchasing volumes, supplier gaps or the commercial viability of a specific project.

Market-entry conditions

Iran’s national standards rules require a Certificate of Conformity for imported goods covered by mandatory standards. Applicability depends on the specific product and standard, so suppliers should verify the current requirement before shipping or making a compliance claim.

What this may mean for exhibitors and visitors

Equipment suppliers may use WATEX to test technical fit with treatment, reuse, irrigation and network-efficiency needs, while checking product-specific standards and service requirements. Visitors may compare technologies against project conditions and request evidence on performance, maintenance and conformity. The market indicators support investigation, not a forecast of demand or a promise of sales.
