Use this tool to find out if your wastewater system needs to be replaced.

From Vestelli you get proven effective wastewater systems. Long-lasting and worry-free Finnish Vestelli treatment solutions are an environmental act.

If the property is located less than 100m from a watercourse or groundwater area, the system must be renewed by law by 31 October 2019. An uncertain property owner can check the location of their plot in relation to the watercourse using the service created by the Ministry of the Environment at www.ymparisto.fi/satametria .

Wastewater legislation in a nutshell – The law’s deadline of October 31, 2019 obliges properties in coastal and groundwater areas, elsewhere only in connection with renovation.

The basic treatment requirement for a wastewater treatment system required by law applies to properties that are located at a maximum distance of 100 meters from a water body or the sea, or are in water supply use or in a suitable groundwater area. The distance from a water body is determined from the shoreline at the mean water level to the wall of the nearest building that generates domestic water.

The wastewater treatment system based on the requirements in force at the time of construction in 2004 and thereafter or the building permit issued at that time meets the basic treatment requirement and does not require changes.

The property owner is always responsible for ensuring an adequate level of treatment of wastewater generated on their property.
