The pumping of water is a basic and practical technique, far more practical than scooping it up with one's hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable location. Regardless of the outcome, the energy required to pump water is an extremely demanding component of water consumption. All other processes depend or benefit either from water descending from a higher elevation or some pressurized plumbing system.
The water pump plays an important role in your car's cooling system and continually pumps coolant and water into the engine. Operated by the drive belt, blades on the pump allow coolant to flow into the engine. Although water pumps are built to last, they sometimes break down and require replacement.
