Fiberglass Reinforced Plastic Water Tanks

Fiberglass Reinforced Plastic (FRP) is a composite material made by reinforcing a polymer matrix with glass fibers, offering the strength and durability of fiberglass combined with the versatility of plastic. It is known for its lightweight, corrosion resistance, and high strength-to-weight ratio. In the waterworks industry, FRP water tanks have become indispensable for applications like potable water storage, wastewater treatment, stormwater management, and industrial processes. These tanks are highly resistant to corrosion and chemicals, ensuring water quality preservation even in harsh environments. Their lightweight construction and customizable design make them easy to transport, install, and adapt to specific project requirements. Below are the detailed applications within the waterworks sector:

Potable Water Storage

The supply of a rectangular FRP water tank to the Philippines. This rectangular water tank is made of fiberglass reinforced plastic panels by a hot pressed moulding process. These FRP panels (1m x 1m) are bolted up to form a water tank.

FRP tanks are widely employed for storing drinking water in both urban and rural settings. Their non-corrosive nature ensures that water quality remains uncompromised over extended storage periods. The non-porous inner surfaces of these tanks facilitate easy cleaning and inhibit bacterial growth, making them ideal for potable water applications.

Water Treatment

In wastewater treatment facilities, FRP tanks serve multiple functions, including acting as equalization tanks, holding tanks, and process vessels at various treatment stages. Their excellent chemical resistance allows them to withstand the harsh environments and corrosive substances typically present in wastewater. In the water purification process, FRP tanks are used to store raw water and water that has undergone preliminary treatment. In desalination plants, FRP tanks are used to store seawater and desalinated freshwater. Their lightweight nature simplifies installation and transportation in coastal areas.

Fire Protection Systems & Process Water Storage

FRP water tanks with multiple flanged interfaces for fire protection systems.

In fire protection, FRP tanks are used to store large volumes of water required for firefighting purposes. Their durability and resistance to environmental factors make them reliable components of fire suppression systems in both industrial and residential settings. Industries often utilize FRP tanks to store process water, including treated water used in manufacturing processes. The tanks’ resistance to a wide range of chemicals and their ability to maintain water quality are advantageous in industrial applications.

Rainwater & Irrigation Water Storage

FRP tanks are integral to rainwater retention systems, where they collect and store runoff during heavy rainfall. This practice mitigates environmental issues such as erosion and sediment deposition in watersheds by controlling the release of rainwater. In agricultural irrigation systems, FRP tanks are used to store rainwater or irrigation water. Their weather resistance and corrosion resistance allow them to be used outdoors for long periods.
