Precolor Sales - 5 Things you Should Know about GRP Water Tanks

April 2025

5 Things you Should Know about GRP Water Tanks
GRP Water Tanks

If you are reading this, then it is quite likely that you are looking for water storage solutions for your property or business. If so, perhaps you have seen GRP water tanks, like the type that we manufacture at Precolor Tank Division. Of course, despite GRP being a very widely used and versatile material, not everyone is familiar with what this material is, or why it is such a good choice for liquid storage units. In this article, we have 5 important things you should know if you are looking for GRP water storage tanks.
1) The name means that they are made from glass reinforced plastic.

If you don’t know what GRP means, it simply refers to glass reinforced plastic. This is a reinforced plastic material. It is created by using a fibre structure of glass, which is embedded in a plastic resin. The combination of the two materials creates an exceptional construction substance. The plastic base ensures that it is waterproof and resistant to UV light, as well as easy to form into any shape, whilst the glass fibre makes it long lasting and strong.
2) GRP tanks are durable, so they are good value for money.

At the end of the day, you don’t want to have to replace your tank. GRP water storage tanks are designed to last for a long time. Of course, the number of years will depend on a number of factors, such as the conditions the tank is kept in or what is stored in it – the more corrosive the substance, the faster the tank will deteriorate. But in the right conditions, and with clean, cold water inside, you could expect the tank to last as much as 30 to 40 years.
3) They are available either as sectional or one-piece cold-water storage tanks.

Small to medium sizes can be formed in a single unit, with no joints or seams. But if you need something bigger, this manufacturing type is perfect for creating GRP sectional tanks.
4) They are easy to install.

Because they are so light whilst retaining strength, GRP water storage tanks are easy to install without needing specialist equipment or skills.
5) There are options available to suit all types of projects.

Whatever you need, there is a unit to suit your requirements. From small to large GRP tanks, single unit or sectional designs, we have the option for you. We can also provide a cover to keep the contents clean, as well as advise if you need to maintain a temperature, filter and process the water, or incorporate the unit into an existing system.

We think that these are five things that you should know if you are shopping for liquid storage solutions. Of course, you might have different questions to ask. The good news is that we are available to answer all your questions. For more information and all enquiries, why not use the online form on our website?

Precolor Sales - Handy Maintenance Tips for Water Storage Tanks

April 2025

A quality water tank is a big investment. This is why you must keep it safe and ensure that clean water runs through your pipes and to your bathroom and kitchen taps to make it last and get your money's worth.

Water storage tanks are designed to withstand extreme conditions and temperatures. Some last for a very long time, but some don't. The reason for this is regular and proper maintenance.

Here are the top factors you need to know to maintain your water storage tank in good condition:

Check tank foundation weekly.

The construction of many water tanks, such as the GRP water tanks, is durable. So, they can last for many years with proper maintenance. If you don't check your tank, it can be exposed to possible hazards such as cracks, corrosion, and deterioration.

Before they become worse, you should be able to detect these risks. Checking them every week will allow you to take action at these risks at their early stages.

Make sure the water isn't contaminated.

You have to keep in mind that water is one of the most crucial components of water storage tanks. So, if you observe anything wrong with the water on the tank, it's best to determine if it's indeed contaminated water before throwing it away. Depending on how severe the impurities are, you can opt to treat the water.

Clean your tank.

If you use contaminated water accidentally, it can result in waste. For instance, if you didn't notice right away that you're using contaminated liquid to water your plants, it can result in killing your plants.

You can save water and prevent it from being contaminated by regularly cleaning your tank. It's easy to do this when you have the following essential tools:

Floor mop
Bucket
Unscented cleaning solution
PPE or personal protective equipment

You can also use other cleaning tools, such as dry towels, wet or dry vacuums, pressure washers, and sump pumps. These tools can help remove stubborn substances that cause contamination and other water problems.

Take care of the coating.

The coating of water tanks goes beyond aesthetics. Some tank manufacturers have coatings to prevent corrosion, and others provide construction with minimal visually-appealing elements. Proper maintenance of the coating can help you save from maintenance expenses in the long run.

You can keep the coating by putting a topcoat layer on your tank every year. You should also remove the water from your tank since the chemicals from your topcoat could contaminate the water and cause plumbing problems.

Remove the algae from the tank.

Some people opt to use translucent or transparent water storage tanks to add beauty to their properties. But, transparent water tanks are susceptible to algae growth. Algae can contaminate water in the tanks and gradually decrease the durability of the tank's structure.

You can remove algae by choosing an opaque water tank. Algae grow when there's ample sunlight. It develops through photosynthesis, meaning it gets its nourishment from sunlight. So, if you remove the light source, it's highly likely that the algae inside your tank will not thrive.

Conclusion

Hopefully, the tips above have given you ideas on maintaining your water storage tank to make it last. They will help keep your tank in good shape while ensuring the cleanliness of the water. However, these tips might not work no matter your efforts if you have a low-quality water tank.

If you're looking for a trusted water tank brand, consider our water storage tanks from Precolor. Our water tanks are quality and versatile. You also get a 10-year warranty that shows how promising and durable our products are. Browse our website to see all the quality water tanks and accessories we have in store.
