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?
Recently there has been a lot of news about South Africa (Cape Town actually) running out of water soon.
I believe Pakistan – and Karachi especially – is almost in the same boat- international organizations have repeatedly been warning us about the impending water shortage, as soon as the coming decade.
There are many many articles on water saving but the government cannot do this on its own- we as citizens have to help out too.
Some basic water saving techniques which can PRACTICALLY be instituted are –
Like Hawaii, the government should create water catchment areas for rain water – especially in Punjab and KP provinces;
Water faucets can and should be changed to modern fittings/devices which save water. I saw a very very interesting concept at https://www.alteredcompany.com/ . Their water aerators/nozzles give a mist – they claim 98% water saving – giving you the same cleaning effects but at a fraction of the water wastage.
Implement recycling “domestic” water for kitchen & clothes washing and things like swimming pools;
Implement “Waste” water (from WC’s and urinals) recycling for gardens and exterior washings (can be used for washing cars, external patios, etc). Admiral Khawar showed us a fantastic recycling concept the Navy has started at Karsaz – I don’t see why can’t implement the same too;
Mini DAMS is a must – starting from the north of Pakistan’s main rivers to as far south as possible, so that our fresh water does not drain into the sea and is instead used productively. Some provinces have concerns that water from such dams would not be used equitably – but if Pakistan & India’s Indus Water Treaty of 1960 can withstand the “test of time”, I’m sure our own provinces can also reach a comprehensive, equitable & binding agreement;
Implement drip irrigation for all our gardens and plants – if the Middle East countries can successfully operate such systems, it should be even easier for us to do!
Tied to this, all water for gardening should be done after sunset;
Domestic staff HAVE to be taught to conserve water (for that matter all our utilities);
Let’s go back to school – literally – and immediately start teaching water saving to all nursery, kindergarten and primary school children!
What are your thoughts- how else can we PRACTICALLY help ourselves and how can the Government help us?
