terugstroomstelsel

A terugstroomstelsel, also known as a backflow prevention system, is a device or set of devices designed to prevent the undesired reverse flow of water or other fluids within a piping system. This type of system is essential in safeguarding potable water supplies from contamination due to backflow, which can occur when there is a pressure difference causing water to flow backward into the clean water network.

The main function of a terugstroomstelsel is to maintain a one-way flow, ensuring that potentially polluted water from industrial, agricultural, or domestic sources does not infiltrate drinking water systems. It is typically installed at points where water is drawn from susceptible sources, such as fire hydrants, irrigation systems, or industrial processes. The system generally comprises check valves, which allow fluid to flow in only one direction, and additional safety features such as relief valves or air gaps to enhance protection.

Backflow prevention systems are regulated by national and local water safety standards, which specify the types of devices suitable for different risk levels. For example, high-risk environments require more stringent devices, such as double check valves or reduced pressure zone (RPZ) assemblies.

Implementing a terugstroomstelsel is a critical component of public health and environmental safety. Proper installation, maintenance, and inspection are vital to ensure their effectiveness over time. Failure of backflow prevention devices can lead to serious health hazards, including infections from contaminated water.

Overall, a terugstroomstelsel plays a key role in protecting water systems and maintaining safe water quality for both consumers and ecosystems.
