Last week I had written about recycling & harvesting rain water (https://dinshawavari.com/2019/08/08/and-the-rains-are-upon-us/). Then we faced rains in Karachi which I have not seen in decades. The “natural” effect of this was the massive misinformation & incorrect (some genuinely mistaken) social media warnings & alerts on the effects of the rains in Karachi.
One post in particular, on the flooding of Malir River, got me thinking. At the outset, let me clarify that these are my personal views and I hope it doesn’t lead to controversy …
Water flowing down Sindh province makes its way into Malir River, which generally lays dry through the year. It’s only when we have sudden rains or this current set of rains when it fills up, and in the latter case, overflowed too.
The major sources of Karachi’s water are the Hub dam, Keenjhar lake & Haleji lake.
Why don’t we “DAM” up the Malir River Basin within Karachi’s limits? Why let the precious rain water go to waste, into the Arabian Sea? If Karachi is seeing its own effects of climate change and our soothsayers predict more of this to come, let’s channelize that water into a massive & natural reservoir down Malir River. A dam in the middle of the City will also become its own, inbuilt tourist attraction (just like Nasser Dam is in Egypt). It’s just a matter of finessing this future dam as the main structural setup is already in place.
There will NOT be any negative environmental effects – in fact it will save water; be a positive social change for the people of Karachi through tourism; it will control the environmental pollutants currently flowing into the Malir River. There will be other benefits!
Do you water experts out there agree to this- or a variation of this idea?
