GRP Water Tank also known as Glass-reinforced plastic tank, is a fiber reinforced polymer designed of a plastic matrix reinforced by fine fibres of glass. It is an low-budget, lightweight, strong, robust material and can be easily formed by using moulding processes. Due to all these features, more and more traditional water tanks are being replaced by GRP Water Tank. In addition, its smooth mirror surface of the panels prevent the bacterial growth. Its repair and maintenance can be easily done externally without any trouble.
