        We have been purchasing Shakti Tanks for last several years for our Real Estate Projects. Our experience with Shakti Tanks is that these tanks are quite durable & long lasting as against other water tanks which we have been previously using. These tanks have zero defects. Moreover as compared to other tanks, these tanks are price competitive & hence value for money. Therefore we have been patronising these tanks in all our Real Estate Projects. We take taken feedback from our clients from time to time & our clients are very satisfied with these tanks. We recommend our colleagues in Real Estate Industry as well as other consumers to patronize Shakti Tanks.

        I have installed a Shakti septic tank, Shakti overhead tank and a Shakti compost bin in my house at Porvorim. The first two have been functioning flawlessly for over four years now, and I am very satisfied with the performance of Shakti products.
