WaterAid, together with the Rural Water Supply Network (RWSN), UNICEF and Resource Centre and Consultancies for Development (SKAT) are behind a movement to promote higher standards of water supply implementation. Recently we launched two videos setting out critical steps by which to ensure boreholes have the best chance of success. Groundwater is a valuable source for water supply programmes because it tends to be available year round when other sources dry up. It can be developed at low cost close to homes and generally does not require expensive treatment. Groundwater represents a third of global water withdrawals. Good practice must be followed if groundwater development programmes are to reach their full potential. If certain steps are not taken, there is a high chance that boreholes will fail, investment will be wasted and people will remain un-served. Good quantities of groundwater cannot be found everywhere. This video highlights the importance of good borehole siting: Drilling contractors cannot be left to construct boreholes without full-time qualified supervision; spot-checking is not enough to ensure a good job will be done. This video highlights the importance of enlisting qualified drilling supervision: Look out for more videos in this series coming later this year.
