One Hole Much Profit (Biopore hole absorption)

People living in urban areas - such as Jakarta - of course already understand that one of the biggest issues of their lives associated with the problem of water. In the dry season ground water supplies running low, it is difficult to get clean water. But in the rainy season, comes the threat of flooding. Awkward.

If we want to actively manage the problem, why not participate by making a hole absorption biopori (HAB) in our neighborhood? Although simple, homemade water absorption hole is no small contribution to the environment.

In the past, making absorption well constrained in this house many technical problems. Well, LRB overcome it because it is made without taking up land, but the ability of water absorption is so great. In the ideal size, ie the hole diameter of 10 cm depth of 100 cm, its maximum absorption capacity can reach 25 liters per m2.

Some of the conditions necessary for effective HAB. Especially about the placement of holes that must take into account watershed. Can the sewers, around the tree trunk, contour changes in the garden or in the park boundaries. Placement distance is very dependent on soil conditions and rainfall intensity, but ideally between holes is 50 - 100 cm.

The hole can be filled absorption of organic waste, either the kitchen or garden waste, which will become food for soil organisms such as earthworms, termites, ants, fungi, and bacteria. Decomposition in the soil shrinkage is marked with its garbage. At that time formed biopori holes, ie, small holes into the entrance of ground water recharge into the body.

Biopori hole will absorb rain water, which means it will prevent flooding and increase soil water reserves. Soil organisms also will improve the ecosystem of the soil so the plants on it participated benefited. Biodegradable organic waste can also be harvested as compost and beneficial to the surrounding gardens. Let us try!

Preparation Steps:

  • Plan the placement of holes in the area around the house. The hole can be placed at a certain distance (50-100 cm) in the area of ​​the yard, around trees, watersheds, or at the bottom of waterways.
  • Create a hole in the ground diameter of 10 cm, depth about 1 m above the surface or ground water. In order to facilitate the making of the hole, has created a special drill. To facilitate drilling, friable soil with water. Each time the drill filled with soil or every 10 cm soil depth, pull the drill and clean.
  • Strengthen the mouth hole with a cementing width 2-3 cm and 2 cm thick. LRB cover can be hollow if it is feared may harm people or pets.

Waste and Fertilizer:

  • Enter your organic waste from the kitchen or the leaves and dry twigs from the garden. Always be compact enough to use cane trash. If the hole is full, move to the next hole, kept in sequence.
  • In a few weeks of garbage will shrink. That's when biopori hole began to form in the soil and increase water absorption. Remove soil that may accumulate on the ground that blocks the entrance of water.
  • Trash the experience of weathering will be in the form of compost fertilizer. Characteristics trash turned into a blackish brown, crumbly and smells like soil. Harvesting can be done with the same drill to make holes.
