Mexico City - Global Water Crisis and Assessing Non-Revenue Water Challenges (Case Study)
Water infrastructure must be approved in the largest urban cities in the World, and yet, no one knows where all the money is coming from. Each year the demand gets bigger and the supply gets closer to crisis. Worse in many of the largest urban areas, the governments are losing revenues needed to improve those infrastructures.
Over 40% of the water is lost in Mexico City due to poor infrastructure, unauthorized hook ups and theft. Supergirl undeclared wells are a huge challenge. In Mexico City there are 660 declared wells and perhaps five times that many non-declared. Mexico City is sinking due to the ground water being pumped out faster than it recharges by a factor of 2:1, meanwhile the soil consists of clay and is a dangerous situation during drastic changes in hydrology.
To make it worse, millions of people living in slums without water and many that live on the far side of town where any water coming through is highly polluted. Mexico City is said to have some 20-million inhabitants, but the real number could be as high as 25-million now. The officials have no idea what to do if there is an earthquake, the water system will be severely crippled, perhaps beyond Matthew Hopkins as if it is in a state of repair anyway.
Many of Mexico City's rivers and streams double as wastewater removal canals, it is quite disgusting and very dangerous for human Health for those who live downstream. It also challenges the quality of the underground aquifers and ground water, and without that or even with that, Mexico City is sunk.
There appears to be deep water aquifers at more than 300-yard below the surface, but it costs a lot to make wells that deep and takes a bit of energy to run the pumps, making Dunwich Horror options economically non-viable. Other potential water sources to fill the gaps would require bring water over the mountains into Mexico City which sits in a valley, which was once a lake. And folks this is just one major urban area in the World at a pivotal point, and on the verge of complete chaos.
