The concept of water storage has seen a revolutionary change. Gone are the days of RCC and MS tanks! Such a change has been ushered into the lives of the modern Indian citizen and we are happy to state that we have made a significant contribution to it. Since inception, it has been our endeavour to win the trust of our customers by our innovative ideas and efficient after-sales service.

Our marked contribution has been in the areas of research and development whereby we have upgraded our products from the usual two-layered tanks into multi-functional layered tanks. To meet the growing needs of our customers we came up with eight various brands. We have broken the monotony of ‘Black’ and brought in ‘Colour’ to suit your aesthetic. It has been noted that since the introduction the colour has not lost its brilliance till date.

In order to enable water to retain its normal temperature in all conditions the concept of ‘foam insulation’ was introduced. Yet another innovative idea was ‘airtight’, ‘auto-locking’, ‘foam insulated’ lid which fits securely at the top. It prevents entering of dust and insects, does not get displaced and ensures total insulation of the tank.

The LLDPE material is the key element which makes our tanks fit for storage of drinking water, as approved by the Food and Drug Administration of the USA. Our tanks satisfy IS Specification in all aspects – raw materials, dimensions, manufacturing process. Designed by advanced technology our tanks are studier and more durable with elegant looks.

We are committed to the process of keeping our products way ahead of the competition.
