Discharge of grey and black water by ships in the polar regions

The Development and Assessment Institute in Wastewater Technology at RWTH Aachen University (PIA e.V.) is conducting the project “The discharge of grey and black water by ships in the polar regions – extent, impact and regulatory options” on behalf of the German Environment Agency (UBA). 

The aim of the project is to collect data and information on the occurrence of black and grey water on board ships travelling the polar regions in order to better assess the impacts on the marine environment associated with discharges of black and grey water along the Arctic and Antarctic Shipping routes.

To do this, the results of published studies on wastewater discharges and their effects on the marine environment in polar regions will first be compiled in a review format. In addition to the compilation and evaluation of existing data, a survey of operators/shipowners of cruise and research ships as well as yachts will provide further insights into the practice of wastewater treatment and discharge on board ships in polar regions. 

The results of the project will be introduced into the work of the International Maritime Organization (IMO) and the Antarctic Treaty Consultative Meeting (ATCM). Proposals for the further development of the applicable international regulations will be discussed. 

Operators of vessels sailing in polar waters are invited to participate in a survey regarding wastewater generation and treatment on board. We would be pleased if you would take part in the survey conducted by PIA e.V. In doing so, you will be making an important contribution to the success of the project.

Sustainable Protection of Water Resources in Southeast Asia

Despite rapid economic growth and development in Asian developing countries, the population lives under poor condition and is not connected to central public supply related to sanitation such as clean water supply, waste management, wastewater management, and safe faecal sludge management. Mostly population discharge untreated wastewater and faecal sludge to the environment. Besides, the government often faces inefficiency such as the operation of inadequate centralized wastewater treatment plants. Those issues create negative externalities as pollution of surface and groundwater, and affect the quality of life unavoidably.

As a result, Decentralized Wastewater Treatment (DEWAT), which can maintain lower-cost technology in terms of operation and maintenance than the centralized wastewater treatment, has been widely encouraged in the development of innovative technology, and in increasing the quantity of production. DEWAT should be preferably installed at single households or small communities.

Presently in Thailand, septic tanks are designed according to owners theory and hypothesis, and there may be technical staff for maintenance in certain periods. It is a fact that there are too few testing institutions and standards for material test and treatment performance of prefabricated septic tank in the completely ASIAN region. By now manufacturers can only get the results in durability and organic matter reduction of septic tanks.

Also, septic tanks are not covered in the scope in terms of production quality and application in many countries. Hence, it is necessary to verify treatment performance that both users and manufacturers can benefit according to quality production and an increasing level of quality and performance. Therefore developing and improving standards in future is fundamental.
