Ålönlahti pilot 2
In the Ålönlahti Pilot 2 project, the water protection and environmental conservation work successfully initiated in the Ålönlahti bay area and its catchment area will be continued. The follow-up project will put into practice the action plan developed during the Ålönlahti Pilot project to improve the water quality and ecological values of Ålönlahti bay.
Water protection measures will be implemented in the area, and local farmers will be encouraged to take part in water conservation efforts. In addition, the project will pilot the use of an aeration device in Ålönlahti bay.


Ålönlahti pilot
In Ålönlahti Pilot project the action plan for Ålönlahti bay and its catchment area is developed to promote the better status of water and natural values both in the bay and its catchment area. The goal is to create a pilot area of water protection at Ålönlahti that will encourage other actors to take water protection actions at the Archipelago Sea and its catchment area. The project supports the aims of the Archipelago Sea program in removing the Archipelago from the list of HELCOM Hot Spots.
The project includes mapping of the possible water protection measures in the catchment area and the bay. The water protection measures are prioritized and cost estimates are calculated. As a practical measure the multifunctional wetland is planned and constructed within the catchment area and sediment analysis are executed from the sediment deposit of the bay. During the project, the old aeration systems are examined, if possible fixed and then tested to survey the effectiveness of the aeration.
In the project the detailed action plan for Ålönlahti is created where the proposals for water protection actions at the bay and the catchment area are prioritized and budgeted. Based on the action plan City of Parainen and Ålönlahti foundation can apply funding for water protection measures. The Multifunctional wetland that is planned and constructed in the project will be one of the examples of water protection measures in Ålönlahti pilot area.

Press Release

A wetland in Parainen improves the area’s natural values and water quality
A new water protection reservoir designed by Turku University of Applied Sciences has been completed at Sydänperti in Parainen. The wetland is designed to improve the water quality of the Gulf of Ålön and the habitat of many plant and animal species. The site of the wetland was chosen on the shore of Sydänperälahti on the island of Ålo, on an old set-aside field owned by the city of Pargas, which has been fallow for many years.
