Project Title: Urban Drainage System Renewal in Châtelleroux, France
Client: Municipal Administration of Châtelleroux
Supplier: Shandong Siffo Plastic Technology Co., Ltd. (China)
Project Overview
The City of Châtellerault in central France faced critical infrastructure challenges in its historic district, where decades-old concrete and clay sewage pipelines had deteriorated significantly. Chronic blockages, root intrusion, and pipe leakage were causing sanitary overflows, road subsidence, and environmental compliance issues, threatening public health and urban livability.The municipality sought a sustainable, long-term solution to modernize the system, prioritizing durability, corrosion resistance, and smooth fluid conveyance.
Challenges
Corrosion Resistance: Required materials capable of withstanding aggressive sewage and chemical exposure.
Long Service Life: Replacement pipes needed to offer a lifespan exceeding 50 years with minimal maintenance.
Hydraulic Efficiency: Smooth inner surfaces to prevent sediment buildup and reduce blockages.
Ease of Installation: Lightweight yet strong piping to accelerate project timelines in dense urban areas.
Environmental Compliance: Meeting French and EU standards for municipal drainage applications.
Solution Implementation
Shandong Siffo Plastic Technology Co., Ltd. provided a comprehensive PVC piping system tailored to Châtellerault's specifications:
Product: Siffo-SN8 PVC-U structured wall drainage pipes (DN630-DN800)
Key Features:
Chemical resistance exceeding ISO 4435 standards for sewage applications
Mirror-smooth inner surface (roughness coefficient ≤ 0.009) ensuring self-cleaning flow
Ring stiffness of 8 kN/m² suitable for traffic loading conditions
Integrated rubber ring socket joints enabling leak-proof connections
Certifications – Compliant with EN 1401, ISO 4435, and French sanitary and environmental regulations.
Project Outcome
Completed within 8 months across 3.2km of urban network:
Zero leakage incidents reported since commissioning (18 months operational)
Flow capacity increased by 35% due to improved hydraulic efficiency
Projected maintenance costs reduced by 60% over 20-year lifecycle
Full compliance with EU EN 13476 standards and French DT-DI-44 regulations
Client Testimonial
