Desalination © ClimateTechWiki and respective owners

Over 97% of the water on earth is unsuitable for human consumption due to its salinity. The vast majority (about 99%) of this is seawater, with most of the remainder consisting of saline...

Domestic water supply during drought © ClimateTechWiki and respective owners

Increasing access to groundwater is a key strategy for household water supply (both potable and nonpotable) during drought. Therefore, drought relief programs in rural areas typically incorporate...

Flood hazard mapping © ClimateTechWiki and respective owners

Flood hazard mapping is an exercise to define those coastal areas which are at risk of flooding under extreme conditions.  As such, its primary objective is to reduce the impact of coastal...

Flood resilience for protected wells © ClimateTechWiki and respective owners

Protected wells can potentially provide a water supply that is highly resilient to flooding. However, improper design and construction can make them vulnerable during flooding. The key...

Flood warnings © ClimateTechWiki and respective owners

A flood warning system is a way of detecting threatening events in advance.  This enables the public to be warned en masse so that actions can be taken to reduce the adverse effects of the...

Flood-proofing © ClimateTechWiki and respective owners

The primary objective of flood-proofing is to reduce or avoid the impacts of coastal flooding upon structures.  This may include elevating structures above the floodplain, employing designs...

Household water treatment and safe storage © ClimateTechWiki and respective owners

Household or point of use drinking water treatment and safe storage (HWTS) provides a means to improve the quality of their water by treating it in the home. These technologies have been shown to...

Leakage management in piped systems © ClimateTechWiki and respective owners

Management, detection and repair of small leaks in a distribution system are critical functions of system operation and maintenance, yet they are often neglected. Large water main breaks can cause...

Post-construction support for water supplies © ClimateTechWiki and respective owners

There is a large and growing body of evidence demonstrating that post-construction support (PCS) increases the success and sustainability of community-managed water systems. This is even true for...

Rainwater harvesting © ClimateTechWiki and respective owners

Rainfall can provide some of the cleanest naturally occurring water that is available. There is considerable scope for the collection of rainwater when it falls, before huge losses occur due to...
