The city of Jakarta with an area of 661.5 km2 has a population of 10,679,951 people in 2023 (Badan Pusat Statistik DKI Jakarta, 2023) producing quite a bit of waste every day. The resulting waste will be transported to the Bantargebang Landfill. Waste that transported and landfilled at the Bantargebang landfill is producing leachate. Leachate is produced by organic waste or falling rain that falls on waste dump sites. Bantargebang Landfill has 3 Insitu LTP (Leachate Treatment Plants) to handle the leachate produced, but currently only LTP 3 is functioning and is still less than optimal. Apart from that, there is also 1 Exsitu LTP (Leachate Treatment Plant) Bersama Sumur Batu which is under the auspices of the Bekasi City DLH, but is intended to process leachate from the Bantargebang Landfill and Sumur Batu Landfill. Currently, the leachate produced by the Bantargebang landfill does not have an adequate leachate distribution route and it falls directly into the available water bodies. The receipt of leachate water at the LTP Bersama Sumur Batu is also through water bodies. Therefore, plans are being made for the distribution of leachate for the active waste zone to LTP 3 and LTP Bersama Sumur Batu so that the leachate produced can be processed optimally before it enters the water body. The alternative route chosen for channeling leachate will be flow by gravity using HDPE pipes. To distribute drainage water, it will go directly into the water body. With a total flow of leachate produced to LTP 3 of 0,3685 m3/second and to LTP Bersama Sumur Batu of 1,0793 m3/second. So the planned leachate distribution diameter on route I3 (towards LTP 3) the largest is 0.433 meters and on route IB (towards LTP Bersama ) the largest is 0.746 meters.
