Infiltration wells are not very suitable in downstream areas, such as DKI Jakarta, where soil absorption capacity is low. The study must be done thoroughly so that infiltration wells do not end up as reservoirs because they fail to reduce inundation and increase groundwater reserves. Berita Terkini
This was conveyed by Muhammad Fakhrudin, Main Expert Researcher at the Limnology Research Center of the National Innovation Research Agency (BRIN).
Fakhrudin said, infiltration wells function to reduce inundation and increase ground water reserves. The condition is that it must be located in an area with highly absorbent soil.
“Jakarta is located downstream, the absorption capacity of the soil is low. The further north, the lower so that it cannot make infiltration wells. Later the infiltration well will only become a holding pond,” he said as reported by Kompas.id, Friday (12/3/2021). Berita politik
Therefore, the recent massive construction of infiltration wells must have a study. It must be ascertained which areas or points have good absorption and location constraints.
Fakhrudin said the principle that the more infiltration wells, the better it would be in vain if building without studying the absorption capacity of the soil and considering field conditions.
Through studies and considerations, the government is able to determine the effectiveness of the infiltration wells rather than the massiveness of the infiltration wells. Berita Hari Ini
“Field conditions, right, are different. Have to make sure it works properly. Also routine maintenance by cleaning garbage, mud, and others,” he said.
Infiltration wells are a mainstay program for DKI Jakarta Governor Anies Baswedan in anticipating floods.
In 2021, the DKI Provincial Government targets to build 25,647 infiltration wells. As of October 27, 2021, the DKI Provincial Government has built 12,482 infiltration wells.
This program was originally to be continued in 2022. The DKI Provincial Government has proposed a budget of Rp. 322 billion to build 26,000 infiltration wells next year.
However, the budget proposal was rejected by the DKI Regional House of Representatives (DPRD).
The faction that refused to consider infiltration wells to be ineffective in dealing with flooding in the capital city. In fact, infiltration wells are said to have damaged the contours of Jakarta’s streets because they were built on the sides of the road without proper execution. Avril Lavigne Fanpage
