Smart Reservoir · Animated concept

Same tanks. Three storm pulses.

120 mm over three days. When the sewer is stressed, tanks hold. When capacity returns, smart release makes space again.

The forecast arrives before the first storm pulse.

Green: controlled release permitted while sewer capacity is available. Red: hold water; even with no deliberate release, other runoff may raise sewer levels. The two tanks represent distributed storage, not measured installations.

Example only: 45 + 25 + 50 = 120 mm of rain over three days. Signal, tank and sewer levels are illustrative—not real Wien Kanal telemetry, authorization, or a calibrated hydraulic simulation.
