About this calculator

The non-potable water demand calculator helps estimate the amount of water required for irrigation and toilet flushing. This demand is a significant part of a building's water consumption, as it does not require potable water. The calculator uses a simple formula that adds the demand for irrigation and toilets.

The formula used is based on the sum of two parts: Irrig (irrigation demand) and vaso (toilet demand). This allows users to obtain a realistic estimate of non-potable demand in their project. It's essential to consider these values to optimize water use and reduce waste.

Non-potable demand is particularly relevant in construction projects that aim for water efficiency. Using non-potable water for irrigation and toilet flushing can significantly contribute to reducing treated water consumption. Additionally, this practice helps alleviate pressure on water treatment systems.

When using this calculator, it's crucial to pay attention to units and input values. The accuracy of the results directly depends on the precision of the input data. Furthermore, it's recommended to consult hydraulic and sanitation experts to validate results and obtain personalized guidance for each case.
