As per Japan's economic daily Nikkei, Panasonic had developed a special photocatalyst to detoxify harmful substances from water to make it potable.
The product has been designed to serve small rural communities where water supply infrastructure is underdeveloped.
Panasonic and Tata will work to lower the purification cost to less than 100 yen ($0.95) per tonne of water in order to make the product affordable for widespread use, Nikkei said.
Tata will offer expertise and business networks in re-examining design and procuring materials locally.
