Legionella Prevention – Drinking Water System Check

Housing companies, landlords and administrators are obliged to provide access to unobjectionable drinking water. This is prescribed by the Drinking Water Ordinance. You can test the water quality by making use of our comprehensive "drinking water system check".

Drinking water should not contain any legionella, i.e. bacteria. This must be checked on a regular basis by lessors of apartment buildings. In December 2012, the Drinking Water Ordinance made new provisions for protecting against legionella.

As an owner or operator you are obliged to have your drinking water installation* screened for legionella: 

  • if you operate a large-scale installation for heating up drinking water and distributing the water to other users in the course of a commercial or public activity, for example to nursery schools or rental housing;
  •  If there are showers, air conditioning systems or other facilities in the apartments or houses you are letting as landlord, where the water is sprayed very finely and could be inhaled.

* Facilities without aerosol-forming facilities are not subject to the general inspection obligation... This includes commercial properties in which only toilets and washrooms are available.
