JAKARTA - Secretary of the DKI Jakarta Water Resources Service (SDA), Dudi Gardesi, said that vertical drainage and infiltration wells have different functions.

Dudi explained that the Jakarta flood control program at the SDA Department is generally called vertical drainage. Meanwhile, infiltration wells are one type of vertical drainage.

"I tend not to use the term infiltration well, I prefer vertical drainage. Vertical drainage consists of infiltration wells, detection pools, like a modular circuit, some with deep wells", Dudi said when contacted, Friday, November 12.

Then, what is the difference in function between vertical drainage and infiltration wells?

Dudi explained that the vertical drainage was made to be a temporary inundation parking lot on the road surface and a flood control device. Thus, vertical drainage does not always absorb water into the soil.

"The principle is that it doesn't have to seep into the ground, the principle is to hold water in such a way, the peak we pass is longer, so that our drainage canals can accommodate all (water)", said Dudi.

Meanwhile, infiltration wells are made by digging holes to find the location of sandy soil, so that it will facilitate water on the surface to enter the soil.

"There are infiltration wells that are modular (round pipes), there are medium depth wells of 20 to 60 (centimeters), depending on the layer of sand underneath to lower the water", he said.
