the 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
They do this anyway...what do u think a water tower is???
Water towers are designed to provide steady pressure through demand spikes. That's completely different from transporting the water.
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????
cool, definitely not a typical network
Sounds like this could be feasible for coastal places that are water-thirsty then? (I mean if, for example, L.A. was self-sufficient (or close to it) on water, that would mean quite a lot for its upstream/uphill neighbors). Today L.A. draws from local groundwater, canals from inland, and the Colorado River Aqueduct- and everyone that also depends on those has to make allowances for LA.
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
Ground water rarely doesn't require pumping.
