Le 7ème Forum du // 7th Forum of the Rural Water Supply Network : Abidjan, Côte d’Ivoire (29.11.2016 – 02.12.2016)
Conclusions & recommendations
• Sand dams are appropriate for areas with:
o seasonal rivers
o low groundwater potential
• Significant buy-in is important from:
o politicians, professionals and community
• Sites for sand dams should consider both technical & social
aspects
• Sand dams require intensive supervision
• It is important to take into account the impact of sand
deposition onto the flood plain as this reduces its water
holding capacity.
