What is the definition of lift in the context of water supply?

The definition of lift in the context of water supply specifically refers to the vertical height from the water surface to the discharge point. This means that when a pump draws water from a source, lift represents the distance the water must be raised to reach the destination where it will be used or discharged. This is a critical measurement in understanding the capacity and efficiency of pumping systems.

In practical terms, when designing water supply systems, engineers must account for lift to ensure that pumps can operate effectively. If the lift is too great for the pump's capability, the system may not function properly, leading to inadequate water supply for intended use.

Understanding lift helps in selecting appropriate pumping equipment and designing effective water distribution systems, making it a fundamental concept in water supply management.
