WESDUN’s Successful Export: Supporting Tanzania’s Municipal Sewage Treatment
In April 2025, WESDUN—a leading Chinese industrial valve manufacturer with over 16 years of experience in R&D, production, and export—successfully delivered high-quality ball valves, gate valves, and check valves to Tanzania. These valves are dedicated to local municipal sewage treatment projects. This partnership signals WESDUN’s deeper engagement in Tanzania’s water and sanitation infrastructure, and provides reliable, heavy-duty equipment to help the country boost sewage treatment capacity and advance environmental protection.

Tanzania’s Sewage Treatment Challenges and National Initiatives
Tanzania faces major challenges in water supply and sanitation. Nearly half of its population lacks access to “at least basic” sanitation services, and the current sewage treatment coverage rate is only 9.7%. In major cities like Dar es Salaam, sewer networks are limited, and many existing wastewater treatment systems—such as waste stabilisation ponds—underperform due to subpar operation, maintenance, and design. To address these issues and meet UN Sustainable Development Goal 6 (clean water and sanitation for all), the Tanzanian government is expanding sewage treatment projects. Its target: 30% coverage by 2030. WESDUN’s valves play a key role in this national effort.
Key Roles of Exported Valves in Sewage Treatment Process
WESDUN custom-designed and precision-built the exported ball valves, gate valves, and check valves to stand up to the harsh conditions of municipal sewage treatment. Each valve serves a critical purpose in the process: Ball valves feature quick 90-degree opening/closing and low flow resistance, enabling precise flow control in sewage pipelines for stable system operation. Gate valves offer minimal fluid resistance and strong sealing, shutting off media in large-diameter pipelines to prevent leakage and ensure maintenance safety. Check valves stop fluid backflow, protecting key equipment like water pumps and extending the system’s service life.

International Standards and High-Quality Assurance of WESDUN Valves
All exported valves meet strict international standards, including EN ISO 4126, ISO 9001-2015, and ISO 14001:2015. They also hold authoritative certifications such as CE, SIL, ATEX, and PED. Made from high-quality ductile iron with stainless steel internal parts, these valves resist corrosion and wear from impurity-laden sewage. They operate at -10 °C to 80 °C and handle pressure ratings of PN 10, PN 16, and PN 25—fully meeting Tanzania’s municipal sewage treatment requirements. WESDUN’s strict quality control and advanced inspection ensure every valve passes thorough testing before shipment, guaranteeing long-term, reliable operation.
WESDUN’s Global Experience and a New Milestone in Africa
With extensive export experience, WESDUN has built strong partnerships with distributors in 47 countries. The company has supplied high-quality valves to numerous overseas infrastructure projects, including water treatment initiatives in Indonesia, Cambodia, and Colombia. The Tanzania export marks a new milestone in WESDUN’s African market expansion. It reflects global recognition of WESDUN’s product quality and technical strength, and underscores the company’s commitment to supporting global water and sanitation infrastructure.

Application Value and WESDUN’s Future Commitment
WESDUN’s valves will greatly improve the efficiency and reliability of Tanzania’s municipal sewage treatment system. They will help reduce pollution from untreated sewage, protecting public health and the environment. This collaboration also serves as a solid model for future water treatment partnerships between WESDUN and Tanzania. Moving forward, WESDUN remains focused on quality and customer needs, delivering high-quality, efficient, and eco-friendly valve products and solutions to global clients—and contributing to better water and sanitation worldwide.
