Fiberglass Reinforced Plastic (FRP) Underground Water Storage Tanks

In line with our innovative approaches, we are introducing Fiberglass Reinforced Plastic (FRP) Underground Water Storage Tanks.  Leakage, corrosion, and contamination of water in the sump or underground tanks made of concrete, brick, or steel are very well-known and documented. In several areas, the roots of trees penetrate and destroy cast-in brick or concrete tanks causing contamination and leakage of water. Sintex FRP underground water storage tanks are designed to provide an excellent alternative for keeping water safe and pure. Made in a state-of-the-art plant under stringent quality control, these tanks are the best and easy means for hygienic storage of water anywhere in the country.
