Ground water rarely doesn’t require pumping.
Comment on Desalination system could produce freshwater that is cheaper than tap water
jcit878@lemmy.world 1 year agothe issue with water networks is they work great when you have the source (usually dams) upstream, water essentially is gravity fed throughout the network with only some localised pumping for certain elevated locations. wastewater again gravity fed towards treatment plants at the lowest point (usually the ocean), so usually, its fairly efficient, despite still requiring enormous amounts of energy.
this doesnt solve that. it has the source where the end point is. the desalinated water needs to be pumped up, to then be gravity fed through the network. In some places, it is worth the cost and energy due to water scarcity, and im not knocking the technology. but claiming its cheaper than tap water is patently false because the distribution cost is far higher

if its a relatively flat coastal location, its possible. FWIW I work for a water utility in a coastal city and we have a desal plant. Ive seen the figures. the cost of desalinated water compared to the catchment water is an order of magnitude difference. Sounds like LA it would be ideal for the environmental reasons alone though

They do this anyway…what do u think a water tower is???
raptir@lemdro.id 1 year ago
Water towers are designed to provide steady pressure through demand spikes. That’s completely different from transporting the water.
jcit878@lemmy.world 1 year ago
you are completely missing the point mate.
desalinated water STARTS at the lowest possible point in the catchment. Rain water does not.

Bruh where I’m at the water starts underground what are u talking about???
jcit878@lemmy.world 1 year ago
cool, definitely not a typical network
