Which factor can lead to increased water loss in distribution lines?

The factor that significantly contributes to increased water loss in distribution lines is the use of poor pipe materials. When distribution pipes are made from materials that are not suitable for transporting water, several issues may arise. Poor quality materials can lead to leaks and breaks, which directly cause water loss. For example, if the pipes are prone to corrosion or degradation over time, the structural integrity of the pipes may be compromised, resulting in a higher likelihood of leaks.

In contrast, regular maintenance, properly designed infrastructure, and frequent testing of water quality are practices aimed at minimizing water loss and ensuring efficient operation of the water distribution system. Regular maintenance checks help identify and repair leaks before they lead to significant water loss. Properly designed infrastructure ensures that the system can handle the water pressure and flow without excessive wear and tear. Frequent testing of water quality ensures that the water remains safe for consumption and identifies potential issues that could arise from the infrastructure, further supporting the integrity of the distribution lines. Therefore, the use of substandard materials is the key factor that exacerbates water loss in distribution systems.
