Project Overview
Roskilde, located on the eastern side of Zealand Island in Denmark, is one of the most important cities in the region. Positioned approximately 30 km west of Copenhagen, it serves as a major urban and administrative center with a growing population and increasing demand for reliable infrastructure.
To support urban development and ensure high-quality potable water delivery, the local government initiated a drinking water pipeline upgrade project. The goal was to replace aging infrastructure with a modern piping system that meets strict European drinking water standards.
Project Challenges
The Roskilde water supply project presented several key challenges:
Strict Drinking Water Standards: Denmark enforces some of the highest water safety regulations in Europe, requiring certified, non-toxic, and corrosion-resistant pipeline materials.
Long Service Life Requirement: The government required a pipeline system with a lifespan exceeding 50 years, minimizing future maintenance and replacement costs.
Continuous Water Supply During Construction: The project had to ensure minimal disruption to daily life, maintaining stable water availability during installation.
Urban Construction Constraints: Installation work needed to reduce noise, traffic disruption, and environmental impact within city areas.
Efficient Installation: Fast and reliable construction methods were essential to meet project timelines.
SIFFO HDPE Pipe Solution
To address these requirements, SIFFO supplied a complete HDPE piping system, including pipes and fittings, engineered specifically for potable water applications.

Key Advantages of SIFFO HDPE Pipes
1. Safe and Hygienic for Drinking Water
SIFFO HDPE pipes are manufactured from non-toxic, food-grade polyethylene material. They fully comply with potable water standards, ensuring no contamination or chemical leaching into the water supply.
2. Long Service Life
With excellent resistance to corrosion, scaling, and environmental stress cracking, SIFFO HDPE pipes provide a service life of over 50 years, even under demanding operating conditions.
3. Leak-Free System
The use of butt fusion welding creates a homogeneous, joint-free pipeline system. This eliminates leakage risks commonly associated with mechanical joints, ensuring water safety and reducing water loss.
4. Fast and Flexible Installation
HDPE pipes are lightweight and easy to handle, allowing for faster installation compared to traditional materials. The fusion welding process is efficient and reduces construction time significantly.
5. Minimal Disruption to Urban Life
Thanks to flexible installation methods and reduced joint requirements, the project minimized excavation work and shortened construction duration. This helped maintain continuous water supply and reduced inconvenience to residents.
Project Results
The implementation of SIFFO HDPE piping system delivered outstanding results:
Stable and Safe Water Supply: The upgraded system ensures consistent delivery of clean drinking water to residents.
Reduced Leakage and Maintenance Costs: Fusion-welded joints eliminated leakage issues and improved system reliability.
Efficient Construction Timeline: The project was completed on schedule with minimal disruption.
Enhanced Urban Infrastructure: The new pipeline supports long-term urban development and population growth.
