The City of Vaasa has developed stormwater management through several projects. Key completed projects include VEMA and KUHA, which have focused particularly on stormwater modelling, load management and baseline data for planning.
This page brings together the main materials and reports from the projects.
The projects have:
- developed stormwater modelling in the urban area
- identified significant load sources
- improved the knowledge base for planning and decision-making
- produced information to support the development of the stormwater system
- supported adaptation to climate change
KUHA (Taking the load under control – Urban water management plan for the City Centre of Vaasa)
The KUHA project was implemented in cooperation between the City of Vaasa and Vaasa Water in 2024–2025. A comprehensive urban water management plan was prepared for Vaasa city centre to reduce the environmental and watercourse load caused by sewer overflows from stormwater and heavy rain events.

VEMA (Network models as a tool in the management of Vaasa’s urban waters)
The VEMA project was implemented in 2022–2024 in cooperation between the City of Vaasa’s Public Utility Services, City Planning and Vaasa Water.
The project developed collaboration and operating methods and piloted the use of network models to support planning and decision-making. The aim of the project was to enable comprehensive management of Vaasa’s urban waters and, in the longer term, to improve the condition of nearby water bodies.
