Water services may be compromised, for example, due to drought or floods. To ensure the functioning of water services in all conditions we need regional cooperation and partnerships, combined networks and emergency water supplies.
Supply networks of water plants cover about 92% and sewage networks about 85% of Finnish households. Water services to other households are managed by means of their own systems, which may be common to several buildings. The municipalities and water supply plants are responsible for water services as required by the Act on Water Services. In other respects the real estate owners are responsible for organising the water services.
