As Russia continues to modernize its municipal infrastructure and industrial capacity, Moscow has solidified its position as a crucial hub for the water management and wastewater treatment industry. For professionals in water supply, sanitation, and environmental technology, the Russian capital offers a packed calendar of high-level forums and exhibitions.
In 2026/27, these events are not just trade shows; they are strategic platforms for discussing import substitution, showcasing new technologies for circular economy, and tackling the challenges of modernizing aging infrastructure. Here is a guide to the most significant wastewater treatment events in Moscow this year.
Spring in Moscow: The Wastewater and Recycling Kick-off
WASMA – International Exhibition of Environmental Technologies
Dates: March 30 – April 1, 2027
Venue: Timiryazev Center, Moscow
The year’s first major event for the sector is WASMA, the International Exhibition of Environmental Technologies. While WASMA has historically been a key event for solid waste management, the 2026 edition has expanded significantly to embrace the full spectrum of the circular economy, with a major focus on water.
Why it matters for wastewater professionals:
Last edition of the exhibition featured a dedicated section for “Wastewater Disposal, Water Treatment, and Water Purification”, alongside sessions on industrial air cleaning and environmental monitoring.
- The Business Program: The event includes a specialized conference on “Treatment of Industrial and Domestic Wastewater” . This is a critical session for engineers and plant managers looking for solutions to meet tightening discharge regulations.
- Who is attending: The exhibition organizers expect a strong turnout from regional water utilities (vodokanals), industrial enterprises, and technology suppliers. Exhibitors in 2026 included major industry players such as Ekomasgroup, BMY, and Inzheko.
- Visitor Registration: Professionals can register online, with ticket prices ranging from 600 to 1000 Rubles, and free passes available via promotional codes from partners.
Late Spring: The Official Forum of the Russian Federation
X Russian Water Congress & VODEXPO 2026
Dates: May 20–22, 2026
Venue: Gostiny Dvor, Moscow
If WASMA is the industry’s practical showcase, the Russian Water Congress is its political and strategic heart. Held annually under the patronage of the Special Representative of the President of the Russian Federation for Environmental Protection, this is the country’s official water forum.
Key features and scale:
The event is composed of two powerful parts: the Congress (a high-level business program) and VODEXPO (the main annual water management exhibition in Russia).
- The Audience: Unlike smaller trade fairs, this event draws governors, ministers, mayors of cities, and representatives of large state corporations. It also attracts significant investment and banking sector representatives looking for infrastructure projects.
- The Exhibition Focus: VODEXPO is designed to showcase modern technologies and digital solutions for the development of the country’s water management complex. Key topics include the construction and reconstruction of hydraulic structures, reclamation systems, and port infrastructure.
- Networking: The Gostiny Dvor venue features individual meeting rooms and press centers, with over 150 federal journalists covering the event.
Autumn: The Giant of Eastern European Water Technology
ECWATECH 2026 (Incl. No-Dig & CityPipe)
Dates: September 8–10, 2026
Venue: Crocus Expo International Exhibition Centre
As summer ends, the industry converges on the massive Crocus Expo for the 17th International Water Forum “Water: Ecology and Technology” (ECWATECH 2026) . Founded in 1994, ECWATECH is the undisputed leader in the region and holds UFI (Global Association of the Exhibition Industry) certification.
What makes ECWATECH unique:
With over 12,000 professional visitors expected and more than 550 exhibitors, this is the largest gathering of water technology professionals in Eastern Europe. The event is supported by the Ministry of Natural Resources and the Ministry of Construction of the Russian Federation.
- The Non-Destructive Focus (No-Dig): A major highlight of the 2026 edition is the No-Dig Moscow exhibition. Given that Moscow’s infrastructure is aging, the market for trenchless technologies is booming (6-8% annual growth). Notably, Mosvodokanal (Moscow’s water utility) now uses trenchless methods for approximately 90% of its pipeline repair and construction projects.
- Comprehensive Coverage: The event covers the full water cycle, including:
- Industrial and Municipal Wastewater Treatment
- Sewage Sludge Treatment
- Desalination
- Pipeline Construction and Repair (CityPipe exposition)
- Water metering and digital dispatch control.
Additional Event: Spring Engineering Solutions
AquaFlame Expo 2027
Dates: February 1–4, 2027
Venue: Crocus Expo, Moscow
For those looking at the intersection of water supply and engineering systems, the AquaFlame Expo serves as an early-year meeting point. Held at the Crocus Expo in early February, this exhibition focuses on heating, water supply, and industrial solutions, attracting international manufacturers and distributors looking to enter the Russian market.
Summary for the Industry Professional
For wastewater treatment specialists, Moscow offers a distinct seasonal rhythm in 2026/27:
- April (WASMA): Best for professionals focused on the intersection of industrial wastewater and recycling within the circular economy model.
- May (Russian Water Congress): Essential for executives and policy strategists needing to understand regulatory direction and investment priorities.
- September (ECWATECH): The must-attend event for anyone involved in municipal water utilities, pipeline rehabilitation (No-Dig), or large-scale industrial treatment solutions.
Whether you are looking to source German pumps, Chinese trenchless equipment, or local Russian automation software, Moscow’s 2026/27 calendar provides a strategic entry point into one of the world’s most demanding water management markets.
