Welcome to finding information, examples and practical tips for water protection!

Tools for water protection is a web-based toolbox providing support for implementing water protection actions at local level. It is designed for professionals and experts who do concrete work, strategic planning or make decisions on water protection in cities, municipalities, companies, NGOs or other organisations. The Toolbox provides information and tools that assist with water protection. In addition to practical tips, tools and background information, in the Bank of Actions you can browse actions that local organisations have already implemented for the protection of local waters and the Baltic Sea – and you can also share your organisation’s own actions! This site was established in 2015 by the EU Life+ funded project CITYWATER, in collaboration with the Baltic Sea Challenge. The first tools are based on the results of the CITYWATER project. The site is now managed and updated by the Baltic Sea Challenge. More tools and actions are needed – please contact us and tell us about your ideas! Read more on page About us!

New environmentally friendly cruiser

Actor: IHA-Lines Ltd   ●   Year: 2011   ●   Address: Meritullintori 6, Helsinki, Finland

© Iha-Lines OyIHA Lines Oy Helsinki Cruises built a new environmentally friendly cruiser for the archipelago cruise traffic in Helsinki region.


The new m/s Doris II cruiser was built in Finland during the years 2009-2011. In the environmentally friendly cruiser the future’s tightening environmental norms and regulations are taken into account. The cruiser uses a low emission diesel technique and engines that consume less fuel. A system which enables collecting of the greywater was added as a voluntary investment. The greywater consists of waste water of cooking and washing. Because of the new system, no waters are released into the Baltic Sea. Black and grey waters are treated on shore by city’s sewage treatment system.


© Iha-Lines OyThe new cruiser’s waste waters, which cause eutrophication in the Baltic Sea, are not released to the sea. Environmentally friendly cruiser offers the citizens and the companies organising the cruises a more environmentally friendly option. The City of Helsinki awarded the company with the Helsinki’s environment award of 2010 competition as a trendsetter. The positive publicity also promotes the development of the company.

Background information

Modern technology reducing the environmental impact was invested in the cruiser. According to the law it is permitted to release greywater straight into the sea. However, the system enabling the collection of greywaters in the new cruiser enables holding on to also these waters until connected to the city’s sewer system.

The cruiser is the first one in its class in Finland to meet the tightened EU requirements. It means investments to the structure and equipment that improve the maritime safety.
