Mangalore, also known as Mangalagiri, region has ample coconut, areca nut, cashew nut and black pepper plantations. Despite the extreme monsoon, the farmers in this belt face the scarcity of water from February till July.

A farmer/agriculturist, Chandra Raj Shetty, with a plot of 1.75 acres on the outskirts of Mangalore city with coconut, areca nut plantation has successfully carried out rainwater harvesting to ensure that he never faces water scarcity even in the peak of summer.

Shetty’s agriculture land/farmland has a huge pond that accumulates rainwater, which is connected to two big wells. These, in turn, havehelped increase the ground water level in the neighbourhood. Dakshina Kannada has an undulating landform with hills and valleys and it helps very much that this plot of land is situated on a low-laying land.

All rainwater from the surrounding areas stretching up to almost 3-4 kms radius runs down towards this artificial lake, filling it completely and then overflowing in streams.

Over the years, the water level of the adjoining wells has risen substantially. Thisharvested water is being utilised not only for his own 10acres farm but for neighbouring farms too. It supplies drinking water for the entire area  measuring 4 sq kms as even during peak summer the ground water level is high enough to cater to the local population. He also tends to cattle and poultry farms for other locals.

The efforts at rainwater harvesting through an artificial reservoir and recycled for agriculture purpose has helped in reducing the water supply bills across nearly 10 acres. This rain harvesting has diluted fluorides, nitrates and salinity.
