|text1='''Effects of drought''': Tend to dry up quickly, especially if unlined; Conflict over water for animals. <br>'''Underlying causes of effects''': Lack of rainfall; High evaporation rates; High seepage rates through base of pond and through dam; Storage not sufficient for demand – silting up of ponds due to high silt load, high level of work in constructing ponds. <br> '''To increase resiliency of WASH system''': Reduce evaporation & seepage; Follow proper construction methods; Reduce siltation so there can be more volume capacity; Promote private ownership of ponds, so that de-silting process more likely; Improve access to low-cost loans with long-time repayment conditions so that farmers can replicate technology; Phased construction until capacity is sufficient for water demand.

* Base of the pond should be impermeable, e.g. unfissured rock or clay, to save costs and prevent having to find a form of lining.
