Pombi yesimbi isina musono inogadzirwa isina weld nenzira dzinopisa dzakadai sekutenderedza kupisa kwakaboorwa. Kana zvichidikanwa, pombi inoshandiswa inopisa inogona kushandiswa zvakare kutonhora kusvika pachimiro, saizi uye mashandiro anodiwa. Parizvino, pombi yesimbi isina musono ndiyo inonyanya kushandiswa mukugadzira petrochemical units.
