Maintenance and inspection of hydrants and water-based firefighting systems

Hydrants and other extinguishing water systems must be checked regularly by a competent person. The following maintenance intervals apply:

  • Annual maintenance: wall, above-ground and underground hydrants, pressure boosting systems and filling and emptying stations.
  • Maintenance every 2 years: "dry" extinguishing water systems
  • Inspection every 3 - 6 years (depending on the federal state): Additional inspection by an expert in accordance with the inspection regulations of the federal states.

CWS undertakes the maintenance and repair of extinguishing water systems such as hydrants of any design or pressure boosting systems. Contact us for a non-binding offer.

FAQ - Extinguishing water technology

We provide answers to the most frequently asked questions about hydrants and other extinguishing water systems.

Why must drinking water be separated from extinguishing water?

An extinguishing water system is only used in case of fire. Consequently, extinguishing water often remains in the extinguishing water pipes for a long time and leads to the risk of dangerous bacteria forming. Thus, a separation of drinking water and extinguishing water is mandatory and required by standards or the Drinking Water Ordinance in order to avoid a backflow of possibly contaminated water.

Is an extinguishing water transfer point also necessary for existing buildings?

The use of approved extinguishing water transfer points is strongly recommended in order to implement extinguishing water systems in a technically flawless and legally compliant manner. CWS will be happy to support you in this.

Must I retrofit an extinguishing water system in existing buildings with a drinking water separation station?

As long as the system is functioning properly without any defects, the operator of the building is not obliged to do so. However, as soon as the system needs to be repaired, we strongly recommend retrofitting the drinking water separation station. This way, at the latest, the inspection expert would demand it when accepting the system.

How often is the maintenance of hydrants and other facilities in the area of extinguishing water technology required?

Hydrants of any design, pressure boosting systems or extinguishing water tanks as well as filling and emptying stations require annual maintenance by a competent person. In addition, extinguishing water systems must be inspected every three to six years (depending on the federal state) by a testing expert or an authorised expert. Furthermore, a two-year maintenance interval is prescribed for the "dry" extinguishing water system. In addition, there are defined operator obligations as well as special regulations for hydrants and other extinguishing water systems.

What is a hydrant?

A hydrant is used by the fire brigade to draw off extinguishing water in the event of a fire. There are the following types of hydrants:

  • Underground hydrant
  • Above-ground hydrant
  • Wall hydrants

Fire hydrants are found in all towns and communities in Germany so that the fire brigade can quickly draw fire-fighting water from the public drinking water network.
