source water for all their needs?

Rainwater flows into rivers and dams, after which it is treated in water filtration plants.
Groundwater is the found underground. It is stored in and moves slowly through geologic formations of soil, sand and rocks. Left alone it would eventually flow into rivers, lakes or the ocean.
A desalination plant uses reverse osmosis membranes to extract freshwater from saltwater, e.g. from the ocean. These membranes are a physical barrier that block dissolved solids like salt, so only freshwater can pass through.
Wastewater undergoes various treatment processes (depending on the region) to ensure it is safe for the environment, with many places discharging their treated wastewater into catchment rivers that supply them. Water from the catchment can then be purified to a standard that makes it safe for drinking.

SCORE
CLUE: Namibia is the driest country in southern Africa. Namibia experiences low average rainfall that is less than Australia’s driest year on record.
CLUE: Perth’s annual rainfall has been declining by about 3mm per year on average. Inflows into Perth dams have fallen from 300 billion litres a year to less than 50 billion.
CLUE: The Antarctic ice sheet contains about 90% of the fresh water on Earth, but it is frozen. There is a small salt water lake near Davis Station.
CLUE: In California, two-thirds of the population lives in an area which received less than one-third of the State’s rainfall. If they relied only on rainfall and ground water they would not be able to supply enough water to meet the city’s needs.
CLUE: Rotterdam in the Netherlands frequently receives very high average rainfall. One of the solutions for storing rainwater within the city is “water parks”. These are public squares designed to catch and store rain water.
CLUE: Israel is a semi-arid region, with limited water resources and worsening droughts. There is groundwater available however with growing water consumption there is significant pressure on these water supplies so additional options are used.
CLUE: On average, London receives about half as much rain as Sydney. They must make the best use of the water resources available to them. The River Thames is part of the longest river in England. Once treated, river water is clean enough to sustain the city.
