Water Absorption-1 : BIOPORES

( for Indonesian version go to : )

Recently the floods disaster happens quite often. It is the time now for people contributing in managing the rain water to be reserved in the ground. That’s the ideal principal in home design for giving contribution to their city, like Jakarta that has problem with floods disaster which is getting more often. The quantity and quality of ground water also have tendency for degradation. This is caused by the unbalances between exploitation of ground water reserve (especially in cities area) with the rain water volume absorbed into the ground.

The recommendation to solve the floods problem and also to return quantity and quality of ground water reserve is: absorbing the rain water into the ground as much as possible. One of the appropriate technologies and environmentally good to absorb rain water into the ground is Biopore Absorption Holes (BAH).

Biopore Absorption Holes (BAH) is a cylindrical hole, made vertically into the ground, with diameter 10-30 cm and about 100 cm depth (if the ground water surface in the BAH location is lower, so the depth is not over the water surface level). The hole is filled by organic garbage to stimulate BIOPORE development. BIOPORE is pores in the shape of holes (small tunnel) made by the activities of ground living things or vegetation root.

Biopore Absorption Holes (BAH) can be done in the following location :

- in the bottom of ditch that used for rain water drainage previously, or

- in the bottom of path that is made surroundings the tree, or

- in the border of garden

There are 3 advantages of Biopore Absorption Holes (BAH) :

1) to improve water absorption

2) to transform organic garbage to be compost and to reduce gas emission of green-house effects (CO2 and methane)

3) to utilize the activities of ground living things and vegetation root, and to solve the problem effected by water flooded like dengue fever and malaria.
