Potable Water Supply

Apologies for being absent for a few days. As I’ve mentioned previously, I’m in the process of moving to Dallas. The packing is ongoing as I am leaving Sunday, but I wanted to take a break and put up a blog post. So on we go.

Without potable (drinkable) water, a new city is not possible. Who would come? They already have poor or nonexistent water supplies where they currently are. According to water.org (http://water.org/country/india/) more than 1,600 people a day in India die from diarrhea. Much of that can be attributed to poor quality water.

This is a core responsibility of the new city and we must deliver. At the same time, we have to keep our costs low. How can we deliver water to each building or house without building the extensive pipe network of other cities?

I propose two methods: 1) Rainwater harvesting which basically means having big drums on buildings to collect rainwater. This water can then be filtered and used by residents. The upside is water collection and filtration is local to each building lowering the cost upfront for us. The downside of this is that rain is unpredictable while demand is constant. The other option is to use a air to water filter. Basically, air would be sucked in, condensed and collected. This water could then be further filtered and used by building residents. A $20,000 unit can produce up to three hundred gallons of drinking water per day. Buildings could monetize their excess water by selling it to other buildings or business but they would be responsible for putting in the pipes.

There are many different opinions on how much water we should be drinking every day. The health authorities commonly recommend eight eight-ounce glasses, which equals about two liters, or half a gallon. Even if we assume one gallon per person in a typical one hundred unit building there is plenty of drinking water for all residents assuming three residents per unit on average. Keep in mind though, that we will still need pipes from the buildings for sewage and to provide b grade water for bathing, etc.

We can combine these two to create a localized, less expensive water supply system. Financially, I am penciling in $40,000 per building to provide this service. This money can be recouped a little bit at a time through a hookup fee for each unit plus a piece of the monthly payment which would go to the building.

Bit by bit I think you can see the city coming together.

That is the rough thinking right now to provide drinking water. Did I miss something?

Make an obvious mistake? Please let me know in the comments.
