Sewage and Grey Water Disposal
With growing regulatory demands and environmental concerns, proper waste water management is more critical than ever. Our dedicated marine waste disposal service ensures that all grey water and black water is handled, transported, and treated in full compliance with MARPOL Annex IV and local port authority regulations.
Understanding Vessel Wastewater: Sewage and Grey Water
Marine vessels operating in port generate two primary categories of wastewater:
Sewage (Black Water)
-
Originates from toilets, urinals, and medical facilities.
-
Contains pathogens, organic waste, and pollutants.
-
Strictly regulated due to its potential environmental and health impact.
Grey Water
-
Derived from sinks, showers, laundries, and galley operations.
-
Contains soap residues, detergents, fats, and cleaning chemicals.
-
Though less toxic than sewage, improper disposal can still damage marine ecosystems.
In Singapore, wastewater management is governed by both international maritime law and national environmental regulations:
IMO MARPOL Convention – Annex IV
-
Regulates sewage discharge from ships.
-
Requires proper onboard treatment or secure storage for shore-based disposal.
Singapore’s Maritime and Port Authority (MPA) Guidelines
Prohibit the discharge of untreated or treated wastewater in Singapore port waters.
-
Mandate use of approved marine service providers for collection and disposal.
-
National Environment Agency (NEA) Standards
-
All marine waste must be transported to NEA-licensed waste disposal facilities.
-
Ensures wastewater is treated safely and in an environmentally responsible manner.
