Sewage Treatment Plants

At Saron Marine, we specialize in onboard environmental compliance services, offering precise and reliable Sewage Treatment Plant (STP) Testing for vessels operating under IMO regulations and national standards. With increasing scrutiny on wastewater discharge and MARPOL Annex IV enforcement, our services ensure your ship’s sewage treatment systems are performing efficiently and remain fully compliant.

Why Sewage Treatment Testing Matters

Sewage discharge from ships can have significant environmental impacts if not properly treated. Regulations require that sewage treatment plants onboard must meet strict effluent standards for:

• Biochemical Oxygen Demand (BOD)
• Chemical Oxygen Demand (COD)
• Total Suspended Solids (TSS)
• Faecal Coliform Bacteria
• pH and Residual Chlorine levels

Failing to comply with these standards can lead to heavy penalties, port delays, or environmental violations. Despite periodical STP effluent testing is not mandated it is a very useful tool for operators to verify the condition of the plants. Saron Marine helps you stay ahead of compliance requirements with thorough testing and reporting.

Our Testing Services Include:

• Sampling onboard in accordance with IMO Resolutions
• Onshore laboratory analysis using ISO and EPA-accredited methods
• Detailed compliance reporting for port state inspections and company records
