Using GRP Pipes in Water and Wastewater Management

The backbone of any water and wastewater management system is the pipe infrastructure. This is how water is supplied to households and wastewater is carried to treatment facilities. Selecting the right pipes becomes very important because of the high possibility of corrosive substances. One of the newest and most suitable material that has emerged is the GRP.

GRP pipe suppliers are among the most in-demand in this category with future network likely to be entirely based on composites like GRP. There High corrosion resistance Water pipes are exposed to high corrosion. We need a material that can withstand the constant flow of water as well as environmental factors like sunlight, UV light, salty conditions and humidity. This becomes all the more important in tough terrains, like high rainfall areas, heavy sunlight or hilly areas where overland pipes are exposed to the weather conditions. Underground  pipes face even more corrosive environment with humidity and microbe action that can slowly leach away any material.

The conditions for wastewater management are even more dire. Apart from the hostile environmental factors mentioned above, the pipes also have to carry the highly corrosive wastewater. GRP is highly resistant to any such corrosion. Other materials get their anti-resistant properties from paint or a corrosive layer that protects the underlying pipe. Unlike these materials, GRP is inherently resistant to corrosion. Which means that it does not need any special treatment.


GRP pipes have a very high strength to weight ratio. This means that the pipes remain very light despite their strength. In fact, for the strength they offer, it is one of the lightest material. This makes their installation incredibly easy, especially in high and rough terrain where transportation and laying them can become challenging.

Acoustic properties

GRP pipes provide better soundproofing than most other alternatives. GRP pipe suppliers often use soundproofing materials between different layers of GRP to further reduce the noise levels. This makes the pipes ideal for residential or commercial properties where sound from water movement may not be welcome.

Smooth inner pipe surfaces

GRP pipes have a smooth and plain surface, both inside and out. Unlike alternative like cemented pipes, there are no rough surface inside. This has considerable advantages when we talk of water and wastewater transportation. Rough surfaces means that water gets trapped and becomes fertile ground for microbe growth, making the inside unhygienic. Over some time the growth can create blockages to the smooth flow of the water inside. The same problem occurs in wastewater transport where the rough surface traps the waste and interrupts the flow of the sewage.

Versatile material

GRP is a very versatile material that can be moulded in any given shape. We can build all components with the same material. This means that GRP pipe suppliers can provide complete infrastructure solutions.

Easy installation

As explained above, GRP pipes are incredibly light for their weight. In addition, it is also an easy material to fabricate. It can be worked upon on-site. This makes their installation very easy. The pipes can be shaped and worked upon as per requirement with less effort and machinery required. The same goes for its installation. In fact, the lightweight makes the pipes easy to install in overhead positions or in rough terrains. The ease of fabrication plus its lightweight also means that the labour costs are comparatively much lower.

Less leakage

GRP pipes can be moulded as per requirement in any given shape. We can create angular shapes without adding smaller parts and joints. This reduces the risks of leaks and spills. This is again very important in water and wastewater transport where leaks can cause loss and insanitary conditions.


Apart from the resistance to corrosion, GRP pipes have high resistance to abrasions and chemicals that are present in wastewater. In fact, it is perhaps the only material that shows prolonged resistance to toxic wastewater. This makes it ideal for water and wastewater transport where we need durable material that can give us consistent quality over a long period of time.

Low maintenance

GRP pipe suppliers have worked in installations where the infrastructure has remained intact for decades with little or no maintenance. High resistance to corrosion and abrasions make these pipes incredibly durable with almost no extra effort needed.
