==Costs==

* High cost of construction – in Sudan, a hafir 80m x 60m x 3m deep (14,400m3) for 400 beneficiaries cost US$8,000. The hafir was completed in 3 months with 190 diggers, did not use food for work but spent the money on tools and installation of inlet/outlet. * * '''Range of scale - Kenya:''' a range from 20 Ksh per m3 (USD 0.27), for a reservoir volume of 5000 m3 (a valley dam constructed by oxen), to 100 Ksh per m3 (1.37 USD), for a reservoir storage volume of 100 m3
