It is heartening to learn that national water agency PUB agreed to supply extra water to Johor at a time of urgent need ("Singapore supplies extra water to Johor"; June 7).
This is an expression of good neighbourliness and diplomacy on the part of the PUB. One hopes that if Singapore is ever in need of additional water supplies, Johor would do the same.
Johor's need for additional water supplies is also a sobering reminder that we need to save water.
This has become especially critical, given the extremely dry weather that has afflicted this region.
While technology can help to ease the lack of water via desalination and Newater, it can only get us so far.
