Urban Reservoir Conservation Simulator

Every water utility plans around the same equation: what flows into a reservoir minus what leaves it, both to customers and to leaks. This simulator models a city's supply reservoir as a live mass balance, in the 3D scene a tank fills and drains while particle streams carry water out to the city and a fraction of it sprays away as non-revenue water at a leaking main. Adjust the population served, how widely low-flow fixtures have been adopted, and how much has been invested in leak repair, and watch the reservoir level, daily demand, daily leakage and net trend respond in real time — the same conservation levers (demand-side efficiency vs. distribution-side loss reduction) that real utilities weigh against each other when planning for drought resilience.
