Water contamination can occur from various sources such as industrial waste, agricultural runoff, or aging infrastructure. It leads to the presence of harmful substances like lead, bacteria, pesticides, or chemicals in the water.
Water quality can be affected by factors like high mineral content, hardness, or presence of impurities. This can cause unpleasant taste, odor, or discoloration of the water.
In certain areas, there may be inadequate infrastructure or insufficient water sources to meet the demand of households. This can lead to water scarcity, particularly during times of drought or population growth.

Faulty plumbing systems, aging pipes, or poor maintenance can result in water leakage. Not only does this lead to wastage of water, but it can also cause structural damage to buildings.
Low water pressure in homes can be caused by several factors, including clogged pipes, valve problems, or water supply issues. It can lead to difficulties in performing daily activities like showering, washing dishes, or laundering.
In certain regions, water supply can be affected by seasonal changes, such as shortages during dry seasons or excessive water during heavy rains.
