Treat wastewater. Protect oceans. Stay compliant.
Every vessel generates wastewater from toilets, sinks, showers, and galleys. Without proper treatment, this sewage can harm marine life and lead to serious compliance issues. A Marine Sewage Treatment Plant (STP) Systems treats wastewater onboard before discharge, ensuring safe operations and environmental responsibility.
Why Your Vessel Needs an STP
Untreated sewage discharge can lead to:
- Marine pollution
- Heavy regulatory penalties
- Port State Control detentions
- Hygiene risks for crew
Marine STP systems help vessels meet environmental standards under MARPOL Annex IV, regulated by the International Maritime Organization.
How a Marine STP Works
Think of it as a mini wastewater treatment plant onboard your ship.
- Collection – Wastewater is gathered from all sanitary sources.
- Biological Treatment – Bacteria break down organic matter.
- Aeration – Oxygen supports the treatment process.
- Separation – Solids settle and sludge is removed.
- Disinfection – Pathogens are neutralized using UV or chemical treatment.
- Safe Discharge – Treated water meets required discharge limits.
Our Marine STP Services
We provide complete system support throughout the vessel lifecycle, including both mechanical and automation control systems:
- STP installation and commissioning

Why Regular Maintenance Matters
A poorly maintained STP can cause:
- Odor problems
- System malfunction
- Non-compliance during inspections
- Environmental violations
Routine servicing ensures consistent treatment performance and longer system life.
Environmental Responsibility at Sea
A properly operating Marine STP:
- Protects marine ecosystems
- Reduces pollution
- Supports sustainable maritime operations
