The linked vid shows waste water recycling in Singapore. They take traditionally processed waste water and add additional processing with micro filtration and reverse osmosis filters to produce high purity water, which is typically used for industrial applications (semiconductor industry in Singapore).

EIA reported in 2015 that Pakistan has an estimated 586 Tcf shale gas reserves, of which 105 Tcf was technically recoverable. In addition, they estimated that Pakistan has 227 billion barrels of of which shale oil in-place of which 9.1 billion barrels was technically recoverable.

The main issue that USAID had with attempting to fund shale hydro-fracking in Pakistan was that it requires vast amounts of water and they thought Pakistan was too water stressed to proceed.

But I found the solution... Waste water recycling. Take waste water from Karachi and other big cities in Pakistan process it like done in Singapore and use it for hydro-fracking our shale resources. It would have no impact on our water supplies. Exxon would be the perfect partner in exploring a pilot. The USA is the world leader in shale hydro-fracking.

Recycled waste water with micro filtration and reverse osmosis will make it too expensive.

a better solution is store flood waters and use that instead.

You can use sea water for fracking... Why waste energy purifying then fracking. ???

There other ways to do it...with artificial wetlands but that takes space. Waste water recycling is far cheaper then desalination (which is also an option). Because waste water doesn't have salts in it like ocean water, the osmotic pressure will be far lower and it would require much less pumping pressure...which requires less energy and cost.

Very bad idea.. you can contaminate your ground water with salt. You must use fresh water for fracking

Formation water is saline. Fracturing is done below of base of fresh groundwater. Sea water may cause some formation comparability issues but is chemically treated to provide fluid-rock comparability (i.e to address critical salinity issues).

Most well post hydraulic fracturing are produced back and most the fluids frac flowback fluid is disposed through dedicated disposal wells into another porous disposal zone.

Most jurisdictions are discouraging fresh water fracs.

Trust me I know a bit about this.

Flood water isn't all that clean, it will require processing as well. We are a water stressed nation. Can we add to our water use like this? USAID didn't think so. Waste water recycling for industrial use must be encouraged in Pakistan.

What happens if there is a leak in the pipe carrying the ocean water to the frack field?

Actually another area where waste water recycling can help is in Thar coal generation. Power plants consume a huge amount of water for cooling. Thar is an arid region may not have the water resources for 10,000 mw of generation. Recycled waste water from Karachi could also be a way of providing water for Thar coal generation.

Are you suggesting pumping recycled water from Karach to Thar area? And how would you do that?

Sorry Karachi was on my mind while typing but it be could be a closer urban area like Hyderabad. My main point is that water must also be considered as we expand our energy sector. Waste water recycling is a way boosting water for industrial use without impacting agriculture or domestic use.

We have plenty of water and million gallons of water is dumped into sea every year. We need to build small dams, lakes and water reservoirs.

Due to some political differences, Sindh government has blocked water canal to Thar area. IK Government should request PPP Sindh government to open the water canal for Thar area.

I would like to believe this but many reports indicate otherwise. The canal to Thar is being blocked by farmers concerned with losing water for crops. Proves my point. Wastewater recycling is a solution to this.
 

Here is a vid on the natural approach to waste water recycling using constructed wetlands. The roots of plants are used as a "bio-filter" to clean the water. It requires alot of space compared to traditional sewage/filtration systems but it is much cheaper. If done properly the water can be reused for industrial purposes. I see no reason why these can be systems can't be built in towns/villages in eastern Sind to supply water to Thar power plants or shale fracking in any part of the country.

I have been talking about Gray water, black water, industrial waste water, building wetland, preventing water evaporation for last 10 years. Search my previous posts and you will find all of it.

We need competent leadership who takes the ownership and build these things. That's' why it’s important to decentralized power to division, district and city council level. We need proper urban planing ministry/institution to divert gray and black water to water treatment plants.
