Water rates

Water rates enable the supply of high-quality drinking water to the more than one million residents of the Helsinki metropolitan area, and the efficient treatment of wastewater to protect the Baltic Sea. On this page, you can learn about the different rates and their determination criteria.

Water rates consist of basic rates, metered charges as well as connection fees and fees for connection work for new customers. Current prices are available in the water services price list and service charge price list. 
We cover all maintenance and production costs of HSY’s water and sewer network with the rates charged for water and connection to the network. No tax money is used towards the maintenance and production costs.
Maintenance and production costs include
  • water supply;
  • treatment and transport of clean water and wastewater; and
  • construction and maintenance of water utilities and the network.
