For normal operation, the water main must be located in the soil below the freezing point. Therefore, laying a water pipeline in the ground will require the construction of a trench. And for this, it is best to prepare a project.
The technical documentation should reflect the following issues:
- Soil structure. That is, its looseness or rockiness.
- Freezing depth in a given region.
- Groundwater accounting and the amount of annual precipitation.
- Temperature of the internal environment in the pipeline.
A trench is dug from the water source (well) to the house to a depth exceeding the freezing point of the soil by 30 cm. To install a water supply on a 20 cm thick bed of sand and gravel. And for ease of work, the width of the ditch according to building codes should be from 50 to 70 cm.
