What is defined as the removal of wastewater and stormwater from structures through a series of pipes?

The process described involves the systematic removal of wastewater and stormwater away from buildings and structures, which is known as drainage. This method employs a network of pipes designed to transport these unwanted water and sewage to sewers or treatment facilities, preventing water accumulation and potential damage to structures. Effective drainage systems are crucial for maintaining hygiene and safety in residential and commercial settings by ensuring that excess water and waste do not pose health risks or undermine the integrity of the property.

Water supply, while also an essential system, pertains to the provision and distribution of clean water to homes and businesses, rather than the removal of wastewater. Ventilation involves the circulation of air, ensuring fresh air enters spaces, and is more related to air quality rather than water management. Filtration refers to the purification process of removing impurities from liquids or gases, which does not specifically address the removal of wastewater and stormwater from structures.
