Indonesia-small islandsTropical Rainfall:

- Enough intensity- Variety duration

- Many problem: flood-drought-food security

No infiltration of rainfall – run-off flow directly to the

S EVERAL STEPS HAVE TO BE DONE FOR DESIGNING RAINWATER MANAGEMENT MODEL :

First step for surveying to the location, it must beobserve how the runoff flowing, so that can be decidedthe location of the wells-trap-rainwater tank.

Second step for analysing the water availability, it mustbe determined the catchment area of rainwater for eachwells-trap-rainwater tank, so it can be known thevolume of rainwater which can be captured and storedin the well-tanks.

The next step is to be determined the dimensions of thecatchment wells-trap-rainwater tank in accordance withthe potential of rainwater that can be captured.The final step is designing drawings of the catchmentwells-trap-rainwater tank.
