Ironically, in March, I had blogged https://dinshawavari.com/2019/03/25/water-water-everywhere-but-not-a-drop-to-drink/.
… and now the rains are upon us and we don’t have any catchment system.
Karachi is facing proper monsoon rains for the first time in decades. It’s a good thing too – it cleans up the city; there is more greenery; the temperature drops; and life is so much more pleasant; and the three major reservoirs supplying water to our City get filled.
What is lacking are individual CATCHMENT systems. Each building can easily have their own rainwater harvesting systems – it doesn’t have to be expensive. After the last set of “rains” a few weeks back (though our rains are nothing compared to what India and Bangladesh have to go through during their monsoons and cyclone seasons ☹) I started reading up on rainwater harvesting systems. In our part of the world, Tamil Nadu leads the way! Brazil, Singapore & Australia are other successful examples.
Just as an example, when reading this website http://www.oas.org/usde/publications/unit/oea59e/ch10.htm, I realized the cost and process of making a catchment system is not prohibitive or unreasonable. It can even work effectively with a simple tarpaulin.
There is a great need for our Government to lead the way in promoting private households, buildings and tall rises to try to catch and reuse rainwater – the WATER IS FREE PEOPLE … we just need to capture this very very scarce resource and utilize it for non-drinking purposes.
