Septic tanks for all boaters in Helsinki 

Anyone sailing in Helsinki can empty the boat’s septic tank in several different marinas safely and with respect for nature. Septic tank emptying sites managed by the city can be found on the map and listed by region. The septic tanks marked with the white-based Helsinki logo on the map are in operation. Septic tanks marked in red are not in working order.
