Description:

Both groundwater protection and sanitation infrastructure serve the same overall goals of safeguarding human health and preserving important ecosystems. However, in both segments the implementation of improvements is traditionally carried out by different professional and institutional sectors, which often results in a lack of mutual cost-benefit analysis. For example, sewer systems constructed within the catchment of groundwater resources (e.g. springs) provide the added benefit of conserving the spring water as drinking water. But, as a reality and
often due to economic constraints, sewer systems are progressively leaking with age and even more, many villages in areas with steep topography or poor economical situation are not connected to sewer systems and still rely on cesspits. In this situation it is necessary to set priorities regarding groundwater deterioration and the financial investment into the sanitation system. The paper demonstrates how groundwater protection measures pay off in the course of 20 years at the example of a medium sized spring in Jordan. Further on, the use of vulnerability maps to set priorities of sewer and cesspit rehabilitation is shown.
