Project Overview

In Eluwai, Kenya, access to clean and reliable drinking water has long been a challenge due to limited infrastructure, environmental constraints, and budget restrictions. The local government sought a cost-effective, durable, and easy-to-install pipeline system capable of withstanding operating pressures of 8–12 kg/cm² while meeting international potable water standards. SIFFO Pipe provided a tailored PVC piping solution that aligned with both technical requirements and fiscal realities.

Challenges

Environmental Factors: The region experiences variable soil conditions and climatic stresses, demanding corrosion-resistant and stable piping.

Water Quality Standards: Compliance with safe drinking water regulations was non-negotiable.

Budget Constraints: Public funding was limited, requiring a balance between upfront cost and long-term value.

Technical Requirements: System pressure rated for 8–12 kg/cm², with an emphasis on longevity and installation efficiency.

Solution: SIFFO PVC Piping System

SIFFO proposed a complete PVC pipeline system certified to ISO 4422, ensuring material safety, durability, and performance consistency. The system design included:

Large-Diameter Pipes (400mm): Used for main transmission lines, optimized for high flow capacity and pressure resistance.

Small-Diameter Pipes (180–280mm): Deployed for branch distribution networks, enhancing coverage while maintaining pressure stability.

Integrated Rubber Ring Joints: Simplifying installation, reducing labor time, and ensuring leak-free connections without the need for complex machinery or specialized skills.

Key Benefits Delivered

Cost Efficiency: SIFFO’s solution reduced total project cost by 22% compared to HDPE alternatives through:

30% faster installation (no welding/fusion equipment needed).

40% lower material costs for equivalent pressure ratings.

Training & Support: Local crews were trained in 3 days via SIFFO’s “Install-Ready” program, ensuring self-sufficiency.

Sustainability: Recyclable PVC material aligned with Kenya’s 2030 green growth agenda.

Pressure Performance: All pipes comfortably sustained operating pressures of 8–12 kg/cm², with additional safety margins for pressure surges.

Health & Safety Compliance: SIFFO’s PVC pipes are certified for potable water, guaranteeing no contamination risk.

Implementation

The project was executed in phases, starting with mainline laying using 400mm pipes, followed by branched networks with smaller diameters. Local teams were trained briefly on joint assembly, enabling rapid and autonomous progress. The entire system was pressure-tested and commissioned ahead of schedule.

Project Outcomes

Water Access: 98% uptime achieved within 6 months of commissioning.

Cost Savings: $180,000 saved in lifecycle costs over 10 years vs. initial proposals.

Government Approval: Model adopted as standard for Kenya’s National Water Harvesting Authority (NWHA) rural projects.

Client Testimonial

"SIFFO Pipe’s solution balanced affordability with engineering excellence. The system’s resilience during the 2023 El Niño rains proved its worth—no leaks or failures despite 150mm/day rainfall."

Engineer James Mwangi, NWHA Project Lead

Conclusion

SIFFO’s ISO 4422-compliant PVC piping system provided Eluwai, Kenya with a sustainable, affordable, and robust water supply infrastructure. By combining material longevity, ease of installation, and full compliance with drinking water standards, the solution met both immediate needs and long-term operational security—proving that intelligent engineering can overcome environmental and budgetary challenges.
