Isitulo sangaseseeyiyeyesixhobo sococeko kwintsimi yokwakha unikezelo lwamanzi kunye nezixhobo zokuhambisa amanzi. Eyona nkalo yobugcisa yeisihlalo sangaseseimodeli yoncedo kukuba ibholithi yokucoca ifakwe kwindawo ephezulu yokuvula umgibe owenziwe ngu-S wendlu yangasese ekhoyo, efana nokufaka i-port yokuhlola okanye i-port yokucoca kumbhobho wokucoca ukucoca i-silt. Emva kokuba isihlalo sendlu yangasese sivaliwe, umsebenzisi unokusebenzisa i-bolt yokucoca ukususa i-silt ngokufanelekileyo, ngokukhawuleza kunye nempilo, enoqoqosho kwaye iyasebenza.

Uphawu lobugcisa lweisihlalo sangasesekukuba i-bolt yokucoca ifakwe kwindawo ephezulu yokuvula i-S-shaped water trap yendlu yangasese ekhoyo. Ibholithi yokucoca iqulunqwe ikakhulu kwizibuko lokuhlola kunye nompu wokucoca. Izibuko lokuhlola lizinziswe kwizibuko eligciniweyo kwindawo ephezulu yomgibe wamanzi obunjwe ngu-S. Umpu wokucoca sisixhobo sokususa intlenga.

Isihlalo sendlu yangaseseebonakaliswa luhlobo oluhleliyo lomzimba womntu xa lusetyenziswa, lwahlulahlulwe lube ludidi oluthe ngqo lokugungxulwa kunye nohlobo lwe-siphon ngokwendlela yokugungxulwa (uhlobo lwe-siphon lukwahlulwe ngohlobo lwe-jet siphon kunye nohlobo lwe-vortex siphon).
