We can have sustainable water

Why are we replacing pipes every generation when it’s not necessary? Why are we allowing corrosion and leakage to pollute our water and environment when we can stop it? Why are we paying more today  for something that lasts half as long when there’s no need to? Why are we generating extra emissions by transporting ductile iron and  steel when we don’t have to? This can’t be right.

It can’t be right because in every case there’s a better, simpler, smarter and more sustainable answer to using concrete, ductile iron and steel to build pipelines for water. And that answer is GRP. GRP pipeline solutions outperform concrete, ductile iron and steel pipes on every dimension. Like plastic, GRP pipes are lighter, easier, more flexible and cheaper to transport and install than concrete, ductile iron and steel. Unlike plastic, GRP are more rigid and can be used to create large-diameter pipes that are strong at low weight.

In terms of CO2 emissions, GRP beats concrete, ductile iron and steel every time. GRP pipes have a lower manufacturing, transportation and lifecycle footprint. They have an expected service life of 150 years or more. They are corrosion-free. And whereas plastic pipes become uneconomic at large diameters because of the thick pipe walls needed to make them robust, the latest impact resistant GRP pipes offer a sustainable and competitive alternative to concrete, ductile iron and steel.

In a world where the demand for water is increasingly stressing available supplies and resources, our industry needs these benefits. GRP’s low flow coefficient, for example, means hydropower schemes can generate more energy from each cubic metre of water that passes through the turbine. It also reduces pumping costs in potable water and irrigation systems. That same low flow coefficient makes otherwise marginal, low-gradient hydro schemes economic, while the light weight and easy handling of GRP pipes make them ideal for bringing water and power to and from remote areas and communities. Plus, GRP pipes last for decades, which supports long pay-back times. They also do not corrode, foul up or clog, and so require virtually no cleaning and maintenance. And what is true for hydropower is also true for potable water, wastewater, industry and irrigation.

With Amiblu GRP pipeline solutions, we are bringing the benefits of lightweight technologies to large diameter pipeline systems. Amiblu is a joint venture between Amiantit Flowtite and Hobas to provide fully sustainable water solutions. Our solutions cover GRP pipes, tanks, CSOs, inspection chambers and more, all engineered for sustainability across the supply chain. Our services include consultancy, engineering design and installation. With Amiblu, we are solving the ‘whys’ and so helping the world meet our growing demand for water – sustainably.
