Why has such a successful City, not had the 'backup proceedure'.. . 'desalination plant' that covers the City and outskirts in place. It beggars belief.
Our family uses over 500 liters of water every single day. Piped straight to the house with constant supply, it costs around 15 USD a month. Gotta love Japan.
Easy, there's 7 of us in our house. We do laundry and take baths every day. Our area actually has some of the cheapest water in all of Japan because of the location. We're right next to Mt Fuji, and in the spring and summer a lot of the accumulated snow cover melts off and gets collected before reaching the ocean.
Reverse osmosis the idiot's expensive way to purify water Cold Steam the efficient way to use the sun geothermal composting rocket stoves any heat source to produce electricity and or distilled water explained from basic concept to employment. Water boils in a vacuum at 75 F or 24 C Two open containers one full of water the other empty connect them at the bottom and water will reach an equilibrium 50 50. If one is sealed except for the connection the other will remain empty because of the vacuum created in the sealed container. Gravity will overcome this vacuum if the containers are taller than 34 feet. If the tanks are 40 feet tall the tanks will reach an equilibrium of water levels at 34 feet leaving six feet of hard vacuum in the sealed tank. This makes a vacuum pump set we need two of them if we were going to distill water as the cold side open tank is used to collect the distilled water from it as the continuous input of water needs to go somewhere. Each sealed tank has four valves three at the top two of those on opposite sides (B&C) one at the very top (D) one at the bottom on the side (A), water-based vacuum pump operations are, Close bottom tank valve A and top tank valve C. Open top tank valve D. Fill sealed tank through top side valve B. Close valve B and D when full. Open bottom valve A. This primes the system to let the warm water in that will vaporize and run through the system when you partially reopen valve B (to control flow rate) and open valve C to its fullest. For only power generation need one pump set and one vacuum tank so we can have a Hot side and a Cold side one to boil the water and one to have the low pressure/vacuum to draw the steam in through the turbine then the cooling coils then to the tank. At the bottom of the cold side, tank is a return pipe with the one way valve to the heat source the one-way valve prevents expansion back to the cold side and as the hot side vacuum chamber is the only outlet for the expanding water and it is drawn by the vacuum the cycle proceeds. You can combine the two and get power generation and distilled water keeping the return line from the power generation system will let you switch if you don't need distilled water on a continuous basis in large quantities. I am going to make one feel free to make one as well it is open source.
I don't know how arrid Cape Town is but in the South Eastern United States it's very humid. My central air conditioner's sump pump pumps about a liter of water every 30 minutes to an hour outside onto the ground for every hour the AC runs. Just an estimate. Depends on the humidity and how hot it is. That would be a good source of water. I wouldn't drink it though unless it was purified or bleach was added to it. Would be good for flushing toilets.
All buildings should be collecting rainwater just like the old cisterns in America. Here in America they try to make it illegal to collect rain water in some states. That's why I dont like most government because they over reach. For the water company I pay you money to supply water to my household its your problem not mine when the water runs low. Maybe you should've used some of that money to figure out ways to get more water.
of course... 10 liters for a toilet.... there is no problem to use only 6 liters... no wonder they have a crisis if use is like that, if this is saving mode
technically speaking we are controlling it by unbalancing the gas ratios of the atmosphere with additional greenhouse gases like CO2 or methane, which in a chain of events change the climate towards a more unstable and extreme weather
