What is the urban water cycle

The urban water cycle brings water from the environment, cleans it, pipes it into our homes and sends clean water back into the environment through a complex engineering process

The urban water cycle is 'man made' created to provide drinking water to homes and businesses, to remove wastewater and sewage, and redirect stormwater away from homes and businesses and into our waterways.

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
