WEFTEC (Water Environment Federation Technical Exhibition) Exhibitor List

This list covers companies expected at WEFTEC 2027 in Chicago. It focuses on water quality and wastewater treatment, so you will see names in pumps, membranes, disinfection, monitoring, chemicals, pipes, valves and plant services. The list is built for practical use. You can scan it before the show, shortlist booths and group visits by hall. It also works as a desk reference after the event, when you need to remember who showed what. The list does not promise that every company will attend or that every contact is reachable. Always treat entries as leads to confirm, not as confirmed attendance on the day.

• Built for water and wastewater buyers
• Helps shortlist booths before travel
• Use after the show for follow-up

Sales teams use exhibitor lists to find accounts that fit their product. You can filter by company type, equipment category or region, then build a target list for the show floor. The list helps you plan who to meet, what to bring and how to open a conversation. It also supports post-show follow-up. After the event, you can check which prospects you missed and send a short note. The list is not a lead list with verified emails or phone numbers. It is a map of who is likely to be there, so you still need to qualify each contact and respect privacy rules.

• Filter by product or region
• Plan booth meetings in advance
• Use for after-show follow-up

For sourcing, the list helps you compare vendors in one place. You can line up membrane suppliers, pump makers and sensor firms side by side. Then you can check which ones offer the capacity, standards or service coverage you need. The directory also helps you spot smaller specialists you might not know. That can widen your bid list or give you a second source. It does not replace due diligence. Prices, lead times and certifications change, so ask each vendor for current details. Use the list to prepare questions, then verify answers directly with the company.

• Compare similar vendors quickly
• Find niche and new suppliers
• Verify specs and terms directly

The exhibitor list is useful for market research. You can see which brands are active in water and wastewater, what product areas they push and how they group on the floor. Over time, comparing lists from different years can show new entrants, exits or shifts in focus. This helps analysts track vendor expansion and product trends. The list alone does not prove market share or sales. It is one signal among many. Use it with public filings, press releases and your own field notes to build a fuller picture. Keep notes on what each company actually showed.

• Track active brands by segment
• Spot new or returning exhibitors
• Combine with other public data

A good visit starts with a plan. Use the list to mark must-see booths, then leave room for walk-ups. Group companies by hall or product type so you do not waste steps. Set a short goal for each stop: a demo, a spec sheet or a contact name. Take notes right after each talk. That makes follow-up easier. The list can also help you split tasks across a team. One person can cover pumps, another can cover monitoring. The event runs October 2–6, 2027, at McCormick Place, Chicago. Check the official schedule for final times and floor changes.

• Mark must-see booths first
• Group stops by hall or product
• Split coverage across your team

This directory is a snapshot, not a guarantee. Company names, booth numbers and product lines can change. Some firms may cancel, merge or send a partner. Contact details may be outdated or not public. Do not treat the list as consent to mass email or call. Follow data protection rules and each company's preferences. When you reach out, say where you saw them and why you are contacting them. If a detail matters to your decision, confirm it with the exhibitor or the official WEFTEC source. Use the list to save time, not to replace your own checks.

• Names and booths can change
• Confirm details before you rely on them
• Follow privacy and consent rules
