Area of application:
Water suppliers, municipalities, or cities are responsible for ensuring the provision of firefighting and drinking water in the required quantity. The quality and supply security of drinking water play a crucial role in this.
To ensure the quality of drinking water, depending on the supply network configuration, flushing of hydrants plays a significant role in preventing contamination of drinking water.
During the hydrant flushing, the pressure and flow, as well as temperature, turbidity, and total volume can be measured and documented with the mag-flux® HTL, to derive an efficient flushing concept and further measures from the findings.
Drinking Water Ordinance TrinkwV
The Drinking Water Ordinance TrinkwV contains guidelines for the quality of water for human consumption. It describes, among other things, the permissible limits of turbidity and other general indicator parameters.
DIN14462:2023-07 deals with the planning, maintenance, and upkeep of hydrants and firefighting water systems. It requires the annual determination of water flow, flowing and static pressure, and the documentation of the determined performance values.
DVGW Worksheet W 405
The DVGW Worksheet W 405 deals with the provision of firefighting water through the public drinking water supply. This technical standard describes the guidelines for firefighting water needs, taking into account the building use and the risk of fire spread.
