Improving the availability of water over space is one of the technical measures to increase the [[Resilient WASH systems in drought-prone areas|resilience of WASH systems]], as more points of water in an area means better access for people and livestock. Different options are:

* Methods to improve the siting and construction of physical structures in order to make them less prone to failure and more efficiently used. Such techniques may also apply in general (e.g. key methods to prevent sub-surface tanks from leaking will also apply in areas not prone to drought) – however, they Different options are included insofar that they help to improve reliability of water availability.:

* Suitable Local recharge, retention/storage methods that take into account and re-use of water, which are increasingly being seen as the high rain intensity that falls most important adaptations for short time periods ensuring water availability and food security to rural and urban populations, especially in developing countries in many areas – such storage needs the face of climate change. * Various methods for gaining more water from rainwater and groundwater sources, some of which are innovative and need further research. * Methods on how to limit impact on existing saline groundwater and how to be able recharge/dilute it. * Methods to not only store enough volume of increase available water to last communities through many months treatment of dry season and/or drought, but also needs non-potable saline water. * Ways to be able to conserve evaporation given the high PET rates improve handpump sustainability since this affects water availability in many areas.
