hujan rencana sebesar 149,70 mm/hari dengan intensitas hujan yang berbeda-beda&#13;
pada setiap catchment area. Periode ulang hujan 5 tahun dan resiko hidrogeologi&#13;
sebesar 67,23%. Lokasi penelitian, Pit Durian PT. JRBM, pada tahun 2017&#13;
memiliki 4 catchment area dengan luasan yang berbeda-beda, debit total sebesar&#13;
12.015,618 m3/jam, terdapat 2 sump yaitu South 1 Sump dan North Sump dengan&#13;
kapasitas maksimal sebesar 12.702 m3 dan 29.596 m3 dan terdapat satu unit pompa&#13;
Volvo KSB LCC-H 200-610 pada setiap sump, terdapat tiga saluran terbuka dan&#13;
satu setling pond utama dengan kapasitas tiap kompartemen yang berbeda-beda.&#13;
Setelah dilakukan evaluasi terhadap sistem penyaliran tambang Pit Durian tahun&#13;
2017, South 1 Sump membutuhkan tambahan 2 unit pompa Volvo KSB LCC-H 200-&#13;
610dan North Sump membutuhkan tambahan pompa sebanyak 1 unit pompa Volvo&#13;
KSB LCC-H 200-610.&#13;
Pada perencanaan sistem penyaliran tambang Pit Durian tahun 2018, Pit&#13;
Durian memiliki 7 catchment area dengan luas yang berbeda-beda dengan debit&#13;
total sebesar 14.393,101 m3/jam, terjadi penambahan sump menjadi 5 sump yaitu&#13;
South 1 Sump, South 2 Sump, South 3 Sump, North 1 Sump dan North 2 Sump&#13;
dengan kapasitas tiap sump direncanakan yaitu sebesar 33.485 m3, 40.745m3,&#13;
35.399 m3, 11.565 m3 dan 20.193 m3 dan membutuhkan 1 unit pompa Volvo KSB&#13;
LCC-H 200-610 pada setiap sump. Sistem penyaliran tambang Pit Durian tahun&#13;
2018 direncanakan memiliki saluran terbuka serta setling pond yang sama dengan&#13;
