  2. 2. Background <ul><li>Ocean : 97 % </li></ul><ul><li>Fresh Water : 3 % </li></ul><ul><li>- icecap and glacier : 68.7% </li></ul><ul><li>- groundwater : 30.1 % </li></ul><ul><li>- surface water : 0.3 % </li></ul><ul><li>( lake : 87 %, river 2 % and swamps 11 % ) </li></ul>
  3. 3. Fact Domestic pollution Agricultural pollution Industrial pollution Soil erosion
  4. 4. Fact ( specially in Major City )
  5. 5. Fact
  6. 6. Fact [ wet season ]
  7. 7. Fact [ Dry season ]
  8. 8. Rainfall mapping <ul><li>Indonesian’s rainfall mapping depends on Geographical location. </li></ul><ul><li>West coastal has more rainfall than East coastal </li></ul><ul><li>Rainfall on the West more than East , ie island series from Java, Bali, NTB, & NTT that connected with narrow strait  West Java is the most rainfall </li></ul><ul><li>The heighest Rainfall is on to the land that has 600 - 900 m over sea level. </li></ul>
  9. 9. Rainfall mapping <ul><li>The average of rainfall in Indonesia are 2000 - 3000 mm/year { it always different every year & each places ) </li></ul><ul><li>Average rainfall less than 1000 mm, covered 0,6% from Indonesia, ie. Nusa Tenggara, & 2 district on Sulawesi (lembah Palu & Luwuk). </li></ul><ul><li>Provinces that have average rainfall between1000 - 2000 mm per year are : part of Nusa Tenggara, Merauke, Kepulauan Aru, & Tanibar. </li></ul><ul><li>Provinces that have average rainfall between 2000 - 3000 mm per year are East Sumatera , South & East Borneo, most of West Java, Center of Java & part of Irian Jaya , Maluku Island & Most of Sulawesi </li></ul><ul><li>Provinces that have average rainfall between more than 3000 mm per year are highland in West Sumatera, Center of Borneo, HIghland in Cener of Irian Jaya & some district in Java, Bali, Lombok & Sumba </li></ul><ul><li>The highest rainfall is in Batu Raden – East Java, it almost 7,069 mm per year </li></ul>

  15. 16. What did we do for rainwater harvesting?
  16. 17. Sumatera <ul><li>Reservoir [ Batam , Riau ]  less of clean water </li></ul><ul><li>Conservation Area [ North Sumatera, West Sumatera ] </li></ul><ul><li>Water Storage [ South Sumatera , Aceh ] </li></ul><ul><li>Banyuasin / South Sumatra, they used water storage 10 x 10 x 5 metres for 1 RT ( Rukun Tetangga = neigbours ) </li></ul>
  17. 18. Java <ul><li>Man made Lake [ Jakarta, Center of Java ] </li></ul><ul><li>Water Storage [ Center of Java & West Java] </li></ul>
  18. 19. Nusa Tenggara <ul><li>Special in ALor supporting by UNICEF </li></ul><ul><li>http://video.aol.com/video-detail/unicef-unicef-supports-rainwater-harvesting-in-indonesia/28930493 </li></ul><ul><li>They made a big tank & collecting with plastic bottle </li></ul>

  20. 21. Water storage that have been used in Indonesian village <ul><li>Large earthenware bowl for water (made from clay ) </li></ul><ul><li>Water storage ( made from bamboo & concrete ) </li></ul><ul><li>Bamboo Pipe installation </li></ul><ul><li>Storage from spring water </li></ul><ul><li>Geomembrane liners ( man made lake )  major City </li></ul><ul><li>Absorbing well in housing </li></ul><ul><li>Aqueduct for resorption </li></ul><ul><li>Using Conblock than concrete for parking area </li></ul><ul><li>Levelling for agricultural land </li></ul><ul><li>Water Conservation area </li></ul><ul><li>Revitalization for Lake, River </li></ul><ul><li>Forest conservation </li></ul><ul><li>Water tank/storage from rainwater on home & building </li></ul>
