- Cost is potentially high – in Kenya a 56 m3 dam cost $4,000 including labour (= $71 per m3 of storage) <br>

- Vectors can breed in open water<br>

- Microbiological and chemical water quality is likely to not be acceptable for direct consumption (see [[Natural ground catchment <br>- Tanks and Open masonry dams provide domestic water reservoir]]), but are not capable of supplying water for livestock or irrigation due to their high demands.
