What Are the Key Applications and Advantages of Fiberglass (FRP/GRP) Storage Tanks?

Fiberglass reinforced plastic (FRP/GRP) storage tanks have become one of the most reliable and sustainable solutions for industrial, municipal, agricultural, and environmental applications. Unlike traditional steel or concrete tanks, fiberglass tanks combine corrosion resistance, lightweight construction, high mechanical strength, and minimal maintenance requirements.

As industries face stricter environmental regulations, safety standards, and efficiency demands, GRP tanks provide long-term solutions for wastewater treatment, chemical storage, drinking water supply, fire protection systems, and bulk material storage.

This article provides an in-depth overview of the different types of fiberglass tanks manufactured by UAB Traidenis, one of Europe’s leading producers with more than 29 years of experience.

Key Benefits of Fiberglass Tanks

1. Corrosion resistance – GRP is immune to rust, oxidation, and chemical reactions that affect steel.
2. Durability – service life of several decades, even in aggressive environments.
3. Lightweight design – easier transportation and installation compared to concrete or steel.
4. Adaptability – suitable for wastewater, chemicals, fuel, firewater, and drinking water.
5. Thermal stability – insulated GRP tanks maintain required liquid temperatures.
6. Cost efficiency – cone-shaped structures eliminate expensive concreting.
7. Sustainability – meets EU and international environmental standards.

Main Types of Fiberglass Tanks

1. Underground and Overground Tanks

Designed for wastewater collection, stormwater management, and municipal infrastructure. Can be installed below or above ground depending on site conditions.

2. Single-Skin and Double-Skin Tanks

• Single-skin tanks – used for general water or process liquid storage.
• Double-skin (secondary containment) tanks – ensure extra safety when storing fuel, chemicals, or hazardous liquids, preventing leaks into soil and groundwater.

3. Chemically Resistant Tanks

Built for aggressive liquids (acids, alkalis, industrial by-products). The fiberglass composite ensures safe long-term operation without corrosion.

4. Thermo-Insulated Tanks

Specially developed for temperature-sensitive liquids, such as drinking water, process water, or chemicals that must be stored at stable temperatures in cold or hot climates.

5. Fuel Storage Tanks

Fiberglass fuel tanks are widely used in energy, transport, and industrial sectors. They provide maximum leak protection, comply with EU environmental standards, and are resistant to hydrocarbons.

6. Drinking Water Tanks

GRP drinking water tanks are certified for hygienic use and provide safe long-term potable water storage for households, communities, and industries.

7. Modular Tanks (up to 5000 m³)

Large-capacity modular fiberglass tanks serve municipal water supply systems, agricultural irrigation, and industrial parks. They are designed for scalable solutions, reaching up to 5000 cubic meters.

8. Dome-Shaped Modular Roofs

GRP modular roofs prevent contamination, improve durability, and reduce evaporation in large reservoirs.

9. Firewater Reservoirs

Critical for fire safety systems in factories, warehouses, and public infrastructure. Fiberglass reservoirs ensure immediate availability of water in emergencies.

10. Scrubbers (Air Pollution Control)

GRP scrubbers are essential in industries for gas cleaning and emission reduction, ensuring compliance with environmental protection standards.

11. Silo Tanks

Vertical silo-type fiberglass tanks are widely used for bulk material storage (grains, fertilizers, or powders) and also for liquid processing in industrial plants.

Typical Applications Across Sectors

• Municipal infrastructure – wastewater treatment, stormwater collection, firewater reserves.
• Industry – chemical storage, scrubbers, process water, fuel storage.
• Agriculture – irrigation water, fertilizers, silo tanks for bulk products.
• Energy sector – hydrocarbons, biofuels, and thermal storage.
• Food and beverage – drinking water, process liquids.

Common Mistakes When Choosing Tanks

1. Undersizing capacity – leads to overflow and operational inefficiency.
2. Ignoring soil and groundwater conditions – critical for underground tanks.
3. Choosing only by price – uncertified tanks may fail environmental inspections.
4. Not considering operational costs – some tanks require chemicals or frequent maintenance.
5. Neglecting EU/ISO compliance – may result in future restrictions and costly replacements.

Expert Recommendations

• Always define liquid type, volume, and storage conditions before selecting a tank.
• Choose EU-certified GRP tanks to guarantee compliance and safety.
• Calculate long-term operating costs – fiberglass tanks minimize maintenance expenses.
• Consult experienced engineers for customized solutions (industrial, municipal, or agricultural).
