Application and main tasks
SUWO water meter wells are used when, for various reasons, a water meter cannot be installed inside a building. Wells are be located on the premises, outside building structures at a distance of more than 1 m – application area “U”. The default location for them is the lawn in close proximity to the plot boundary – usually no more than 2.0 m. A properly installed SUWO water meter well is a maintenance-free device, requiring minimal and occasional maintenance. Depending on the type chosen, it can ensure complete tightness.
The primary task of the SUWO water meter well is to protect the water meter installed in it from freezing. A properly installed well protects the water meter and fittings when the ambient temperature at ground level is no lower than -30°C. The various well models use different physical phenomena to counteract the freezing of water in the water meter area:
Depending on the geographical location and thus the local weather conditions, the ground has a certain maximum frost depth. In the vast majority of Poland, the ground freezes to a depth of 0.8-1.0 m. Only in the mountain areas and in the north-eastern part, the freezing reaches 1.2-1.4 m.
