Welcome to find support for water protection!

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!

Improving streamflow in a strait

The Water Protection Association of Haavainen has implemented dredging in the strait of Haavainen to improve the streamflow. Haavainen is located in Lokalahti, south of the City of Uusikaupunki, Finland.

In the project, the strait was dredged in the length of altogether 250 metres to reduce the silt in the bottom and to decrease the amount of vegetation in the shallow strait. As a result the streamflow has now increased also during low water. After dredging, the channel was marked to serve boaters in the area.


The challenge in the strait of Haavainen is the old bridge and the built embankment around it, which decrease the streamflow and thus have a negative environmental impact in the area. The dredging helped to open the strait, and the streamflow between Haavainen and Tuppiluoto (neighbouring water area) improved. The action stops the strait from slowly becoming blocked through shallowing and vegetation.

Background information

The action is continuation to the Association's earlier project, funded by the European Regional Development Fund (ERDF) and implemented in cooperation with the regional Centre for Economic Development, Transport and the Environment. The project was also funded by the City of Uusikaupunki. The Association's long term objective is to get the bridge and the embankment around it renewed, and thus improve the streamflow even more. Planning has begun with funding from Leader programme.
