We will determined the needed of sewage pump, and all the specification of calculation. Sewageis include in the crews live and their accomodations. The pump specification must be can backup for everyday. Sewage tank need to be fitted a air pipe to the open deck and sewage tankmust install a filling connection, rinsing connection and level alarm.
This document purpose is to determine the technical specification of sanitary discharge system.
