A water budget has been described as what?

• A. A record of water usage from meters
• B. A plan for rainfall harvesting
• C. A schedule of irrigation times
• D. Volumetric allotment of water for customers.

Answer: (D)

A water budget is the volumetric allocation of water for customers within a system. It defines how much water can be used over a set period, balancing available supply, system losses, and environmental needs. This makes it a planning and allocation tool rather than simply recording usage, planning for rainfall harvesting, or scheduling irrigation times. For example, a utility might set a per-person daily allotment and use that budget to guide conservation efforts, pricing, and drought responses. The budget represents the expected or allowed volume of water, not the actual measurements from meters or the timing of irrigation.
