'''Volume of reservoir''': From a few cubic metres to many thousands. <br>
'''Uses''': De-silting and storing raw water.
==Resilience to changes in the environment==
====Drought====
'''Effects of drought''': Badly made concrete and cracked linings (e.g. in tanks, dams, waterways, wells, and other structures). <br>
'''Underlying causes of effects''': Less water used for curing; Impure water used for mixing. <br>
'''To increase resiliency of WASH system''': Ensure adequate mixing, ratios, purity of ingredients; Minimize water content in mixture; Ensure adequate curing.
