Customer Testimonials

I’ve been using Dunaplast water tanks for years. The quality, durability, and hygiene are unmatched. Truly reliable and long-lasting, perfect for my family’s daily water storage needs.

Rohit Jaiswal Banmankhi, Purnia

We live in Banmankhi, and summers here are unbearable. Our Dunaplast tank has been working perfectly, even during peak heat.

Poonam Kumari Kasba, Purnia

In Kasba, water pressure fluctuates a lot. But Dunaplast’s 1000L tank has made storage easy. It fills quickly and stays sealed tightly.

Ramesh Yadav Dhamdaha, Purnia

We recently renovated our house in Dhamdaha and installed a Dunaplast tank. It’s sturdy, stylish, and requires almost no maintenance.

Nazia Parveen Araria

Living in Araria, we get strong sunlight all day. Our previous tank used to get hot quickly. Dunaplast’s UV protection makes a difference.

Amit Singh Bhawanipur, near Purnia

Our joint family in Bhawanipur needed a big tank, and Dunaplast’s 2000L was a perfect choice. The build is strong and the lid fits tightly.

Rafiq Alam Baisi, Purnia District

We shifted to Dunaplast on our farm in Baisi. Even in open exposure, the tank doesn’t show any wear and tear. Excellent durability.

Lalan Shaikh Jokihat, Araria District

From Jokihat, where we face water issues during summer, Dunaplast has been a lifesaver. Water stays clean for days without any odor.

Neelam Devi Katihar

In Katihar, we tried multiple brands, but none lasted more than 2 years. Dunaplast is the only tank that’s still like new after 3 years.
