Every Drop Counts. Every Drop Matters.
Assess, improve and optimize rainwater harvesting for smarter and more sustainable urban water management.
200 m² roof · 700 mm rain
≈112,000 L/yr potential
Up to 70%+
of dense urban land can be impervious, generating runoff

1 mm × 1 m²
of rain on a roof = up to 1 litre of potential water

Less
dependency on groundwater extraction
Smarter
and more sustainable stormwater management
Why Urban Areas Need Rainwater Harvesting
Water Scarcity
Increasing urban demand puts pressure on available water resources.
Groundwater Depletion
Excessive extraction can steadily reduce groundwater levels.
Urban Flooding
Impervious surfaces increase stormwater runoff and waterlogging.
Rainwater Wastage
Large quantities of rainfall flow directly into drains, unused.
