Water Loss refers to the difference between the amount of water put into a water distribution system and the amount of water that reaches paying customers. This is a crucial area in water utilities where professionals work to find, measure, and fix problems that cause water to be lost through leaks, meter inaccuracies, or unauthorized use. Think of it like checking a leaky bucket - these specialists help water companies save money and conserve resources by finding where the water is escaping. Related terms include "Non-Revenue Water" or "Water Loss Control," which all describe efforts to make water systems more efficient and sustainable.
