Instead of the ugly water towers for large cities, made of
concrete, why not have the water towers made of glass (at
least on the side not exposed to the sun) and have fish living
in it, wth a bio-filter system that keeps the water clean and
Same goes for the large water reservoirs.
They could be
replaced with large ponds sustaining life, and biologically
checking the health of the water. (There are types of snails
and fish that can live only in very clean and unpolluted water.)

||In michigan a lot of the reservoirs are large ponds that ducks love to swaddle about in, and some are "nature preserve" types that have walking paths and the likes. Not sure about the aquarium though, the water would have to be heavily treated upon leaving the aquarium for it to be used as drinking water. I thought the whole point of a reseviour was a large supply of ready-to drink water and to buffer the original source like a lake or whatnot.
||If you have a lake then you most likely don't need a
reservoir. We have the "Sea" of Galillee from which
the whole country drinks (and grows agriculture and
uses for industry). That was so until they discovered
the fossil water in the Hatzeba desert. Except places
like Jerusalem which has a reservoir for water
pumped up from the hills below. Of course the
Kinerret (Sea of Gallilee) has fish and ducks and other
animals in it. And of course the water is filtered and
tested before being sent to the rest of the country.
||[+] for moving me one step closer to having a pet coelacanth.
||But coelas are deep sea saltwater...
||I liked the wikip entry: This discovery 65 million years after they
were believed to have gone extinct...
||There were believers 65m years ago!
