There are a wide variety of different types of water tank designs available in the marketplace. The most common materials used to create water tanks include fibreglass (or GRP – Glass Reinforced Plastic), PVC, steel, and concrete. Over time, the fibreglass design has proved ideal for water tanks because it provides a variety of benefits other materials do not.
The first benefit of using a fibreglass design is durability. A GRP water tank is molded through a combination of high temperatures and pressure. Additional stainless steel can be added to prevent erosion within the tank. On the other hand, a PVC water tank can become fragile as it is exposed to weather variations which inevitably lead to damage. Steel water tanks can also be adversely affected by weather leading to cracks on the laminated surfaces and eventually corrosion. The same is true for concrete.
Another benefit of using a fibreglass design is cleanliness and sanitation. A GRP tank has extremely smooth surface which prevents dirt adhesion and limits bacterial growth. It also allows in enough light to prevent algae growth as well. PVC, steel, and concrete water tanks all present unique sanitation and cleanliness issues which can only be overcome by implementing a system of constant vigilance. For example, PVC water tanks are prone to algae growth and water contamination because light and dirt easily get through the manhole cover.
Installation and maintenance of a water tank with the fibreglass design is easy. Any repairs and maintenance can be done X currently without interrupting the water supply. If irreparable damage occurs, it can be solved by replacing the damaged panel using only basic hand tools. On the other hand, other types of water tanks are not as easy to install and maintain. For example, PVC water tanks must often be completely replaced if they are broken or damaged. Steel water tanks require constant maintenance in order to minimize corrosion. Concrete water tanks have uneven services which require significant water pressure to wash and the typical flat bottom eliminates the possibility of complete drainage during maintenance. This can lead to contamination of incoming water.
A final benefit of a fibreglass design water tank is transportation and handling. GRP water tanks require the lowest overall skill level to assemble and transport. Not only does this mean only basic tools are required, but the total hours of labor required is minimal. PVC water tanks utilize a one-piece design which can make it difficult to transport them onto rooftops of buildings.
Compared to the other options currently available, it is clear the fibreglass design is the best solution. It offers all of the benefits expected from a quality water tank without the drawbacks associated with other materials.
