Exemption from connecting to the water and sewer networks

A building in the operational area of the water management plant (HSY) must usually be connected to the plant's water and sewer networks.

This connection obligation does not apply to unbuilt real estate. More information about connecting to the water and sewer networks can be requested from HSY.

Exemption from connecting to the water and sewer networks can be applied for through the City of Helsinki Environment services. This exemption can be granted if all the exemption criteria listed in the Water Services Act are met.
