  • Practical technical solutions for

dealing with sewage in ports and effective waste water management

  • Exchange of information on

quantities and qualities of wastewater, as well as capacities

  • Received from:

– BPO – Port of Tallinn – Sweden

  • See revised document:

– Technical Guidance not meant to stipulate any mandatory solutions for ports, but to present technical options for specific technical challenges – Focus on ports, however, cruise ships‘ responsibilities addressed (e.g. timely notification/ exchange of information/ sufficient pumping capacity) – Policy issues (e.g. fee systems) not included

Updated questionnaire

  • Received from Port of Gdynia

– New data to be included

Example Capacity Issue: Insufficient Capacity

Improvement of discharge capacity

  • Installation of fixed PRF
  • Installation of storage tank
  • Different types increase flexibility

Provision of additional pump station

  • Pump connection on both sides

(ship and port) Tank trucks mainly as “Plan B” options or for special waste streams (sludge or food waste)

  • Discharge rate depends on PRF (e.g. 150 m³)
  • Discharge to MWTP starts when cruise ship

discharges to PRF

  • No positive effects
  • Discharge rate depends on storage capacity
  • Discharge to MWTP starts when needed
  • Positive effects:

✓ Balancing of diurnal pattern ✓ Discharge on demand of the MWTP
