Project Overview
The City of Dakar, Senegal, faced a critical challenge with its aging municipal water distribution network. Decades-old pipelines suffered from severe leakage, leading to significant water loss, inconsistent supply, and compromised water quality. With a growing population of approximately 800,000 relying on the system, the government initiated an urgent upgrade project. Key requirements included a new system meeting potable water standards, long service life, safety, reliability under operating pressures of 8-12 bar, and minimal disruption during construction to ensure continued daily water provision for residents.
Challenges
Deteriorated Infrastructure:
Existing pipes were heavily corroded and leaky, wasting precious water resources.
High Performance Demand:
The new system needed to withstand constant pressure (8-12 bar) and deliver safe drinking water reliably to a large population.
Complex Urban Environment:
Construction in a dense urban setting required techniques that minimized traffic disruption, excavation time, and social inconvenience.
Continuity of Service:
A strict mandate to avoid prolonged water cuts, necessitating rapid installation and connection methods.
Solution: SIFFO HDPE Piping Systems
SIFFO proposed a complete High-Density Polyethylene (HDPE) pipeline system, recognized for its durability, flexibility, and corrosion resistance. The core of the solution lay in its jointing technology:
Butt Fusion Joining: Used for long, straight sections of pipe in main lines. This method creates seamless, leak-free joints as strong as the pipe itself, ideal for withstanding the required pressure.
Electrofusion Joining: Employed for repairs, branch connections, and fittings in confined or complex areas. It allows for quick, reliable, and strong connections with minimal excavation.
Implementation
Phased installation was planned to segment the network. SIFFO provided not only the certified PE100-grade HDPE pipes and fittings but also on-site training and technical supervision for the local crew on fusion techniques. The ductility of HDPE allowed for longer coil lengths in smaller diameters, reducing joints and installation time. For crucial intersections or repairs, electrofusion fittings enabled work to be completed within hours, often during lower-demand periods, ensuring daily water supply was maintained as required.
Results & Benefits
Zero Leakage, Full Integrity:
The monolithic, fused HDPE network eliminated leakage points, conserving water and stabilizing system pressure.
Long-Term Reliability:
HDPE's resistance to corrosion and chemical degradation ensures a lifespan exceeding 50 years, meeting the government's longevity requirement.
Rapid, Disruption-Minimized Construction:
The efficiency of fusion joining accelerated project timelines. Reduced excavation and the ability to perform quick tie-ins dramatically lessened impact on traffic and daily life.
Guaranteed Supply Continuity:
Strategic phasing and fast connection methods prevented extended service interruptions, aligning with the civic objective.
Safety & Quality Compliance:
The system consistently delivers water meeting potable standards, and the inert material eliminates risk of contamination.

I. International Certification and Comprehensive Quality Assurance
Municipal water supply pipelines are critical to public health and infrastructure safety; therefore, product compliance is the fundamental prerequisite. Shandong Sifu has obtained multiple authoritative international certifications—including ISO, CE, and WRAS—and has undergone audits and certification by third-party agencies such as SGS and BV.
Equipped with state-of-the-art testing facilities, the company implements rigorous dual-stage inspections covering both the production process and the pre-shipment phase. Its products strictly adhere to various international and Chinese national standards, such as GB/T 13663, EN 12201, and ISO 4427. Through comprehensive quality control spanning the entire lifecycle from raw materials to finished goods, the company ensures that every exported batch of HDPE water supply pipes meets the high standards required for municipal engineering projects regarding core performance indicators such as pressure resistance, sealing integrity, and service life.
II. Product Performance and Hygienic Safety Characteristics
Designed for municipal drinking water supply applications, Shandong Sifu’s HDPE piping products offer the following key performance advantages:
Hygiene and Safety: The pipes are manufactured from virgin PE100 material; they are non-toxic and free from heavy metal additives. The smooth inner walls prevent scaling and bacterial growth, ensuring no secondary contamination of the drinking water.
Durability and Corrosion Resistance: Under normal operating conditions, the pipes have a design service life of at least 50 years. They also exhibit excellent resistance to chemical corrosion, impact, and abrasion.
Fluid Transport Efficiency: The smooth inner walls and extremely low friction coefficient facilitate high flow capacity, helping to reduce long-term energy consumption in municipal water supply systems.
III. Comprehensive Specification Range and System Integration Capabilities
Shandong Sifu offers an extensive range of pipe diameters—from DN20mm to DN1600mm—with pressure ratings spanning PN 0.6 MPa to PN 2.0 MPa.
Furthermore, the company positions itself as an integrated provider of HDPE piping systems, offering a wide array of compatible connection fittings, such as electrofusion and butt-fusion fittings. This one-stop supply capability streamlines the procurement process for overseas municipal projects and ensures the integrity and compatibility of the piping system, from the main network down to branch connections.
IV. Large-Scale Production Capacity and Agile Delivery System
Located in Shandong Province, the company operates a factory spanning over 25,000 square meters with an annual production capacity of 100,000 tons. With a workforce comprising more than 20 engineers and over 100 production staff, the company possesses the infrastructure and human resources necessary to handle large-scale municipal export orders.
Leveraging over five years of export experience, the company is well-versed in international trade procedures and compliance requirements. It is capable of meeting order demands with delivery lead times ranging from 7 to 30 days, thereby effectively shortening procurement cycles for overseas municipal projects.
V. Professional Technical Team and After-Sales Support
One of the company's core competencies lies in its technical expertise. Shandong Sifu is the first National High-Tech Enterprise in Hedong District and boasts a team of highly skilled technical professionals.
For municipal water supply projects destined for export, the company offers not only standardized products but also technical support to assist clients with pre-sales material selection and pipeline structural design. Regarding connection methods, the company employs various proven techniques—such as electrofusion and butt fusion—to ensure that joint strength exceeds that of the pipe itself, thereby guaranteeing the long-term sealing integrity, safety, and reliability of municipal water supply networks.
