A City Built on Water Is Running Out of It

Mexico City was built on an ancient lake and gets more rain than London, but it's still running out of water. For millions of its poorest residents, getting enough is a daily challenge. To solve this critical problem, Social enterprise project Isla Urbana is capitalizing on the city's abundant rainfall with home-harvesting systems designed to help the most vulnerable.

@@MWENDA-vv5im less effective AND more expensive. It only kills bacteria, it doesn't remove any contaminants. It should be followed by RO to filter out the contaminants to make it potable. Too much chlorine can cause diseases in the worst case and taste bad in the best case and you don't need chlorine for rain water harvesting because there isn't much bacteria in rain water sliding down the roof. We get untreated water from a nearby river(because it is clean enough for most purposes other than drinking) and we use a gravity RO which doesn't even use energy and just clean the filters every month and replace them every two years and they're cheap, 20usd to replace. However you may need to add chlorine if your water comes from a stagnant lake.

Here in the Philippine capital Metro Manila, it is prohibited to have or use groundwater extraction to prevent ground subsidence. Our water supply comes from 2 privately owned Water Treatment Plant Companies that gets their water from different dams. We also buy bottled water if some don't want chlorinated water or just did not trust tap water for drinking. In our 7 person household typically we pay 10-20 USD a month for our water bill. Only time we experience water supply disruption is during drought or a pipe repair.

Yes almost every single mega-city in the world lacks urban planning and faces huge problems like this. New Orleans is sinking too. Much of Florida and the East coast of the U.S. will be under water in 100 years.

Can learn from China how they rejuvenated Beijing and neighbouring provinces by refilling underground water with the Grand Aqueduct project

[@lzh4950]

IIRC mainland China also built canals to divert water away from other parts of the country to Beijing (under the South-North diversion project I think), & people living in those other parts felt it ironic I think that they weren't allowed to touch the water flowing it those built canals

[@louisazraels7072]

usually, where there is water truck business there is some kind of cartel controlling it, it's just a type of commodity that's heavily subjected to this kind of things. I hope this guy wont get intimidated into giving up promoting this awesome system. They said the water truck service is government provided but who knows who the contractors are... That's a lot of business he is compromising, I really hope I'm wrong.

Convert the toilets Change the system, by isolating toilets to be flushed with Salt Water. Which we have plenty of right now. Plastic pipes would have to be used and a separate treatment system. Yes a lot has changed here, but we're all smart people.
