Water Distribution Efficiency

Water distribution efficiency involves using innovative methods to achieve the same goals with less water consumption. This technology encompasses strategies like drought-resistant plants, xeriscaping, rainwater harvesting, greywater recycling, and low-flow plumbing fixtures. Such approaches curtail the reliance on municipal water sources, subsequently reducing energy demands for pumping and treatment, thus contributing to climate change mitigation.

The smart park irrigation system calculates the amount of water each area needs depending on the state of the soil, weather forecast, and irrigation calendar.
