What is GRP Water Tank?
GRP water tanks is the abbreviation of Fiberglass Reinforced Plastic water tanks,are leading industry and civil standard water storage equipment on the market.There are many advantages such as lightweight,strong structure,modular and sectional assembly by standard panels design. GRP tanks provide safe environment with no risk of bacteria corrosion.
Furthermore,Due to the raw material to manufacturing water tank is self-resistant to bad weather and high temperature,meaning the water tank lifespan is long.Meanwhile,all raw materials attribution decides the water tank is pliable,application wide for any specific access or needs.

Elevated (Overhead) GRP Panel Sectional Water Tank vs Ground GRP Water Tank
According to the installation position, GRP panel water tanks (called FRP water tank or SMC water tank) can be categorized into elevated (or overhead) water tanks and ground (or on-ground) water tanks. Here’s a detailed description of each type:
Elevated GRP Water Tank (Overhead GRP Water Tank)
Installation Position: Installed at a height, usually on top of a tower, steel support structure, or building rooftop.
Purpose:
Provides gravity-fed water supply, eliminating the need for continuous pumping.
Ensures stable water pressure for residential, commercial, and industrial applications.
Commonly used in municipal water supply systems, high-rise buildings, agricultural irrigation, and firefighting systems.
Structural Features:
Requires strong supporting structures (concrete or steel towers) to bear the weight of the filled tank.
The tank is often designed with corrosion-resistant coatings to withstand outdoor exposure.
Can be constructed in modular panel form for easy transportation and assembly.
Advantages:
Energy-efficient: Uses gravity instead of relying on pumps.
Reliable water supply even during power outages.
Disadvantages:
Higher installation cost due to the need for a support structure.
Requires structural reinforcement for earthquake and wind resistance.
Ground GRP Water Tank (On-Ground Water Tank)
Installation Position: Installed directly on the ground or on a concrete base/foundation.
Purpose:
Used for water storage in factories, fire protection, agriculture, and residential areas.
Serves as a backup water supply in case of shortages or emergencies.
Structural Features:
Typically modular and assembled using galvanized steel panels.
Often equipped with inlet, outlet, overflow, and drainage pipes for efficient water management.
Can be customized in various sizes and shapes to fit available space.
Advantages:
Easier installation with lower structural requirements.
Scalable: Can be expanded by adding more panels.
Disadvantages:
Needs a pump to distribute water at higher pressure.
Takes up more ground space, which may not be ideal in urban areas.
Comparison Summary
| Feature | Elevated GRP Water Tank | Ground GRP Water Tank |
|---|---|---|
| Installation | Installed on steel towers or concrete supports | Placed on concrete base or embedded into the ground |
| Water Supply | Gravity-fed system, reduces need for pumps | Requires pumps for water distribution |
| Maintenance | More difficult due to height, needs scaffolding | Easy access for cleaning and inspections |
| Initial Cost | Higher, due to support structure | Lower, no elevation structure required |
| Operation Cost | Lower in long term (uses gravity) | Higher due to continuous pump operation |
| Typical Applications | Rural water supply, agricultural irrigation, backup use | Urban water systems, residential buildings, factories |
