Sintex started with a Rotomoulding division to manufacture plastic water tanks and other rotomoulded products. In 2008, the new Spintex factory was built with ultra-modern machinery to further expand the range of products and production capacity. The plant now manufactures a range of plastic storage tanks with capacities starting from 600 liters to 25,000 liters.

Sintex Water Tanks are manufactured with high quality polyethylene materials which include UV resistance properties to withstand tropical environments and increase their durability.
