'''Dew collection''' can bring substantial amount of water when the other resources (groundwater, rain, fog) are lacking. Rainwater harvesting structures can also be used to collect dew at night, which condenses on a surface from where water droplets drip into a gutter that goes to a reservoir. Quantity from dew varies according to location but at times has been shown to constitute a significant proportion of normal rainfall. Dew collection is a possible supplementary source of water in arid and semi- arid areas, but has so far not been widely applied and is an area of further research.

===Suitable conditions===

- Variability in water collection, which also varies according to the season. Need to supplement water from other sources. <br>
