The
legacy from British raj and the local knowledge - Tantalising tunnels,
scintillating stories
An idea is born
In 2000, I was working as Program
Manager – Karnataka for the Indo-Norwegian Environment Program (INEP ). The councilor of Norway had suggested that I
replicate the ‘Sourabha’ (First ecofriendly home of Bangalore) model of
sustainable living, especially the rainwater harvesting technology that I had
used in my house, in public buildings in the City of Bangalore. I hoped to get
an entire locality – Vidyaranyapura – with four layouts, to harvest rainwater
and make the entire community independent of City water supply. But I was told
that public grant cannot be channeled into individual houses. I was directed to
implement my proposal in public places or Government Housing Quarters. I chose
10 landmark buildings and 2 exhibition plots for the project. And of the 10
landmark buildings, the two that gave me sleepless nights but immense
satisfaction were the Vidhana Soudha and the High Court. Here’s why.

Every drop counts
The High Court building in Bangalore was built by the British years and years ago. None of the PWD engineers I spoke to seemed to know where the rainwater pipes were. In desperation, I scrambled on the rooftop, poured water on the roof and raced down to follow its trail! And, in the process, I discovered many startling facts:
a) All the rainwater pipes in the High
Court building are hidden in pillars which are inside thick walls.
b) There is a tunnel in the High Court
basement which exits towards the eastern side of the Court building inside
Cubbon Park.
c) This basement tunnel connects to an
underground stone masonry tunnel, which exits at the Lotus Pond inside Cubbon
Park.
There is a ruling that no construction
activity can take place inside Cubbon Park. I had to seek special permission
and ensure that the flora and the fauna were undisturbed. No blasting activity
or the environmentalists would have had me! My challenge, therefore, was to
intercept rainwater inside the tunnel at 15 ft below from ground level, design
filtration systems for it and store it – 15 ft below the ground level as I
could not mess around with the heritage building. And we – my team and I –
achieved the impossible. We began work in 2003 and by the end of 2005, we had
the RWH system in place.
