BIOPORES: Solutions for Overcoming Floods

Updated: Feb 7

Increases in population are usually accompanied by the expansion of residential areas, business areas such as shops, offices, roads, and other supporting infrastructure. However, due to limited land in city centres, the development of cities has expanded towards the outskirts so that the built-up areas increase, resulting in a reduction in water catchment areas and resulting in greater water run-off.


Biopore is a method used to process organic waste into fertilizer and absorb rainwater. The function of the biopore itself is to increase the absorption capacity of the soil, improve the quality of ground water, convert organic waste into compost so that it can fertilize the plants around the biopore.


Often times, floods occur because the drainage system is not good, especially in densely populated areas, water absorption capacity is reduced because the undeveloped land area gets smaller and more land is covered with concrete.

Therefore, a solution is needed to minimize the occurrence of flooding due to high rainfall. One of them is through making Biopore Holes.

Here are four reasons why Biopore absorption holes can be an alternative solution for dealing with flooding.

1.  Accelerates Rain Water Absorption.


Biopore absorption holes can help water to immediately enter the soil. Apart from that, the organic waste in the hole is food for earthworms. Worms that enter the hole will make small tunnels in the soil as they lead to the hole containing organic waste. This will certainly make the water seep into the ground more quickly.


2.  Increase the Capacity of Soil to Hold Water.


Small tunnels made by earthworms will increase the surface area of ​​the soil. This will certainly increase the soil's capacity to hold water. In fact, this biopore absorption hole is able to increase the area of the absorption area up to 40 times.


3.  Biopores can be Made on Limited Land.


Biopore holes can be made in various types of land as long as the land is in an open area that is exposed to rainwater, such as in the yard, around trees, parking lots and other open places.


Imagine if every house, office, or every building made biopore absorption holes, then the amount of rainwater that would immediately enter the ground would be large, thereby preventing flooding.


4. Balancing Water Content in Soil


Biopore helps balance water levels in the soil with the help of soil creatures, such as worms. Worms that live in biopore holes eat organic waste and make small tunnels in the soil. This allows the soil to absorb more water and increases its water absorption capacity by up to 40 times. Thus, biopores help maintain water balance in the soil, which is useful in avoiding drought or excessive waterlogging.


With the presence of biopores, rainwater can seep into the soil more efficiently. The holes in the biopores allow water to seep vertically, thereby reducing flooding in urban areas. Apart from that, biopore is a technology that can prevent stagnant water which can become a breeding ground for mosquitoes and the transmission of diseases such as dengue fever.


In the long term, biopores also have a positive impact on the environment, because they can maintain soil stability and water quality.



 Best Locations for Making Biopore at Home


Biopores are an effective method for improving groundwater quality at home. Biopore infiltration holes made at home can help absorb rainwater into the ground efficiently, thereby reducing the risk of flooding and maintaining the sustainability of groundwater sources.


However, when you want to make a biopore at home, it is important to choose the best location so that the absorption hole functions optimally. There are several factors to consider when determining the location of the biopore at home.


  • Choose an area that has soil that is soft enough and easily penetrated by water. Hard or dense soil can prevent water from seeping into the soil properly, making biopores ineffective. If the soil in your yard is too hard, the soil needs to be loosened first.


  • Also pay attention to the presence of trees or plants around the biopore location. Avoid making biopores near large tree roots, because these roots can hinder the water absorption process. It is better to choose an area that is free from large roots or plants with strong roots.


  • Also make sure the location of the biopore is in an area that is not exposed to puddles of water or water channels that form when it rains. If the biopore is flooded or is located in an area that frequently floods, the water absorption process will not be effective. Choose an area that is high enough and safe from puddles of water.


  • Also consider the accessibility and safety of the biopore location. If you want to carry out routine maintenance or clean the biopore, make sure the location is easy to reach and safe for carrying out these activities.


Ingredients for Biopore:


  • Drill the soil

  • PVC pipe and cover that has holes in the sides

  • Organic waste

  • Water




1. Determine the location of the absorption hole.

2. Water the desired location with water so that the soil becomes loose and soft.

3. Punch a hole in the ground with a diameter of 10-15 cm using a biopore drill or using a crowbar.

4. Dig a hole 100-200 cm deep.

5. Insert PVC with holes if the soil structure has collapsed easily.


Biopore Care:


  • Fill the biopore absorption well with organic waste

  • Leave the biopore absorption well for three months

  • Take compost from biopore absorption wells
