Shikha Rai re-dug and re-built the entire drainage system. It was specially tricky because the crossover bridges built by residents to enter their driveways, had to be cut and new crossover ramps were built by SDMC on each driveway of each house. The storm water drains were covered by porous RCC slabs, so that cars can be parked and rain water can flow into the drains and road muck was restrained. The effect was really dramatic. Every monsoon the streets, which were ankle or knee deep with water earlier, got drained away much faster.

Retired Embankments are constructed at a distance from the river edge behind the existing embankment as a second line of defense. When Retired Embankments are constructed along both sides on high ground, sufficiently away from the river bank, more or less straight and little away from river channel to minimize the risk, they are sometimes called Flood Embankments. This is a very effective system and a neat solution to Flood Control where conventional methods of providing closer embankments are not effective.
India can look forward to join hands with Nepal in harnessing the hydropower potential and after fulfilling all Nepal’s internal needs avail surplus hydropower from Nepal to meet its own power demand besides augmentation of river flows in non-monsoon period and considerable flood control benefits in monsoon season.
China is the only neighbour, with whom India has geographically shared water resources, but there is no water sharing treaty so far. There seemed to be a great degree of timidity in this matter in the past, but it is changing now. The present government is now asserting itself as it holds national interest above everything else.
