Desalination, which produces usable water from saline water, has a higher LCW than processing groundwater or surface water. A 2020 study found that advances in decarbonization would reduce the levelized cost of water produced via desalination from €2.4 per cubic meter in 2015 (US$2.84) to €1.05 per cubic meter in 2050 (US$1.24).

Water tariffs vary widely in their structure and level between countries, cities and sometimes between user categories (residential, commercial, industrial or public buildings). The mechanisms to adjust tariffs also vary widely. Most water utilities in the world are publicly owned, but some are privately owned or managed (see water privatization).

However, the need for extremely pure water for particular industrial uses would still require freshwater imports.
