What is GRP Water Tanks Used for?

Jun. 10. 2022

GRP tanks or glass-reinforced plastic tanks are now the leading industry standard water containers on the market today. Given its lightweight, robust, and serviceable fiberglass design, GRP tanks can safely store water without the risk of corrosion or bacterial contamination. In addition, given the materials the tanks are made of, they are also resistant to external temperatures and harsh weather, meaning the tanks will not degrade over time. These materials also make the tanks pliable, which means they can be adjusted at the manufacturing level to meet any specific access or location needs. 


GRP or glass-reinforced plastic is also commonly referred to as fiberglass. The GRP materials used to manufacture our water tanks are rigorously tested and approved for contact with drinking water (health or potable), ensuring that water is stored under optimal conditions and ensuring the highest standards of water quality.


Compared to other materials, glass-reinforced plastic (GRP) offers many advantages, such as corrosion resistance, lightweight, and a high strength factor. If properly maintained, GRP tanks should last up to 25 years, during which time you do not need to worry about repainting or repainting the tank during its lifetime. However, it is important to take care that the tank is inspected and disinfected annually to prevent any harmful bacteria from entering the water supply for human consumption, which is a good etiquette.

A vast range of tank accessories including float valves, overflows, outlets, level monitoring & level control equipment, tank foundations & support frames, ladders, drip trays, and more.


Uses of GRP water tanks 

GRP tanks are used in a wide range of applications. Popular uses include rainwater storage, so homeowners and companies alike can become more environmentally friendly and reduce wastewater; impregnation tanks for manufacturers to paint their goods; and fire sprinkler reservoirs to ensure that water is maintained in the event of a fire in a commercial building. In addition, the materials they use allow them to be adapted and manufactured on a professional level for storing chemicals in a safe and controlled environment in the workplace.


Temperature and Storage

Temperature also means everything when it comes to water and chemical storage. Keeping the temperature in the tank below 20 degrees Celsius will ensure that the risk of bacterial growth is greatly reduced. Using pre-insulated GRP tanks, water can be kept within the maintenance temperature range, meaning that this microbial growth can be prevented at the source. Insulation is available in a variety of thicknesses depending on the consumer's needs, but typically the insulation is around 25 to 100 mm thick. When it comes to water storage, peace of mind is everything - the ideal tank is one that can be purchased, installed, and used individually without worrying about the integrity of the tank or the sanitary standards of the water being stored.

Design flexibility and customization

Given their inherent materials, GRP water tanks are fully customizable units; they can be manufactured in virtually any shape and size, depending on the consumer's requirements. The color of the tank is also customizable, an important feature for companies storing large quantities of hazardous and non-hazardous chemicals; color customization allows for immediate identification of the GRP tank and its contents.


This level of consumer customization means that instead of getting stuck in a "one size fits all" scenario, tanks can be manufactured specifically for a company's needs without the company having to adapt its workflow and environment for the tank.
