As many as 20 personnel of West Jakarta Water Resources Sub-agency are deployed to install three septic tanks on Jalan Sekretaris, RT 15/07, Tanjung Duren Utara, Grogol Petamburan.

Its installation has been carried out since Wednesday in three locations of the citizen's homes.

"Our target this year is to install 21 septic tanks," expressed West Jakarta Water Resources Sub-agency Head, Purwanti S, Thursday (10/10).

Her party previously wanted to use septic tank belongs to PD PAL Jaya. But it was cancelled because of size too big.

"So we had to replace it with small ones and we target it to be finished in two weeks," she stated.

Before it is used, the septic tank would be given with waste decomposing bacteria thus it is not full quickly.

"The septic tank cover uses steel so it is easy to do maintenance and suctioning," she said.
