Improving the availability of water over time is one of the technical measures to increase the [[Resilient WASH systems in drought-prone areas|resilience of WASH systems]], as more water is available to span increasing length of dry seasons, or, relevant to agriculture, short dry spells. 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.

* Suitable storage methods that take into account the high rain intensity that falls for short time periods in many areas – such storage needs to be able to not only store enough volume of water to last through many months of dry season and/or drought, but also needs to be able to limit evaporation.

* Suitable management of a variety of water sources, where for example open water sources are used first so that most is used rather than evaporated, leaving other stored water for later.
