- Experience shows that sub-surface tanks often cannot hold enough water for whole dry season. Making bigger berkeds is possible but more difficult and cost is high (unaffordable tank is not replicable on larger scale).<br>- Flotation of the tank may occur in areas with a high groundwater table.<br>- Heavy vehicles driving near to tank can cause damage.<br>- Leaks in sub-surface tanks are hard to detect.<br>- Artificial catchments take up potentially valuable land surface and are difficult to keep clean. Concrete catchments tend to crack.<br>- When built in a remote area, construction is difficult due to lack of water and large distances to transport materials.<br>- Water quality is likely to be unacceptable for direct consumption, treatment recommended.
