GRP Potable Water Pipes
and Water Mains
Our promise: Safe transport and storage of our most vital resource
Clean drinking water is a basic right. Yet over 2 billion people worldwide still don’t have access to safely managed drinking water services, and many existing networks struggle with leaks, contamination, and rising energy costs. With cities growing fast and water sources becoming harder to secure, infrastructure must deliver potable water reliably and efficiently for the long run.
Amiblu GRP potable water solutions are engineered to meet these challenges. Our pipes are certified for drinking water use worldwide, helping protect water quality from source to tap. Amiblu potable water pipes comply with major international regulations, including Kiwa, WRAS, NSF, DVGW, and other regional certifications.
For peak demand and remote regions, Amiblu provides custom-built GRP water storage tanks which can be expanded as communities and requirements grow. Together, these systems help ensure reliable drinking water supply for generations.
Why choose Amiblu solutions for potable water
Amiblu potable water products are certified to a number or standards for drinking water used worldwide, with good performance in pressure applications and leak-tight piping systems with joints that prevent contamination.
The exceptionally smooth inner liner of Amiblu GRP pipes maintains high hydraulic efficiency over decades, lowering pumping energy and costs.
GRP pipes combine high structural strength against soil, traffic, and seismic loads with corrosion resistance, and their ability to use larger backfill particle sizes helps speed up installation and reduce overall costs.
Designed for every challenge
These pipelines offer high mechanical strength, excellent corrosion resistance, and a long service life. Their smooth internal surface reduces head losses and energy consumption while limiting deposit formation to preserve water quality. Amiblu GRP piping systems comply with all applicable drinking water regulations and are suitable for both primary and secondary water supply and distribution networks.
Where drinking water must be produced through desalination, our corrosion-resistant, potable-water certified GRP pipe systems ensure safe, reliable conveyance of sea water to the desalination plant, and on to distribution networks and to the tap. They protect water quality and perform reliably in demanding coastal environments where other pipe materials struggle with corrosion.
Amiblu provides a turnkey service for EPC contractors worldwide, covering the construction of water treatment plants from initial studies and stress analysis to design, manufacturing, quality control, delivery, on-site installation, and pressure testing.
Amiblu GRP tanks for potable water storage are custom-tailored to project demands. Their lightweight, modular design makes transport and installation easy, and capacity can be expanded as communities grow.
