The publications in this series cover a wide range of subjects-from computer modeling to experience with water user associations-and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to improve the management of land and water resources for food, livelihoods and the environment. In serving this mission, IWMI concentrates on the integration of policies, technologies and management systems to achieve irrigation and water and land resources.

“…The typical heights of these dams ranged from 1 to 4 meters above the surface 3,19 . There were two types of construction: one using a wall facing filled with bricks or stones, and the other a timber framework filled with stones and mortar, but when stones were not available, other materials (e.g., plastic foil, galvanized iron, or clay lugs) were used.…”

A subsurface dam is a facility that stores groundwater in the pores of strata and uses groundwater in a sustainable way. These dams have many merits that surface dams do not, e.g., land is not submerged to store water and there is no danger of breaching due to natural or manmade disasters. In addition, the surface area can be used in the same way before and after construction of the subsurface dam. Because of these merits, there are many underground dams in the world. This paper reviews the basics about underground dams, the construction of underground dams around the world, and the problems involved in the sustainable use of groundwater. According to a recent review of the construction of underground dams, the scale of underground dam projects has grown. Some problems with underground dams reported in the past, i.e., sedimentation, flooding, collapse, and salination, occurred because of human error, as well as the immaturity and complexity of geological features. In terms of water quality, long-term monitoring was carried out after construction of underground dams on Miyako Island, Japan. To deal with any problems, countries must exchange information gathered from their experiences in constructing underground dams.

Sand-storage dams have proven to be a successful water harvesting method and potential solution to water and food security issues in semi-arid regions such as south east Kenya. This paper examines the microbiological quality of water both contained in the sand dam via test holes and abstracted from it through covered wells and scoop holes. In total, the values of thermotolerant coliform (TTC) concentration, turbidity, and pH are presented for 47 covered wells, 36 scoop holes, and 29 test holes, as well as the conductivity values in conductivity in 39 covered wells and 11 scoop holes. The water from test holes and covered wells was microbiologically of better quality than the scoop holes with median TTC levels of 0/100 mL and 159/100 mL respectively. However, the median values of turbidity for both scoop holes (20-30 NTU) and covered wells (5-10 NTU) exceed the World Health Organisation (WHO) guideline values. In addition the conductivity of water from 23% of scoop holes and 26% of covered wells is above the recommended WHO limit. This study also found that sanitary surveys are not a useful indicator of water quality in sand dams; however, they can identify areas in which sanitation and improvement of water sources are needed.
