SOLUTION / PUBLIC SOURCE RECORD
Aiwell Water increases drainage capacity to prevent urban flooding
- Published 2 December 2022 and updated 21 September 2026. Aiwell Water’s mechanical siphonic drain system switches from gravity drainage to airless siphonic flow when pipes approach overflow. It can retrofit existing drainage networks without power or street excavation. The page claims at least 40% more flow on flat terrain and up to 200% or more as slope increases; in a Norwegian pilot, stormwater capacity doubled and costs were 65% lower than excavation and replacement.
- The solution addresses heavier rainfall and urban runoff that can exceed drainage capacity. It can be used in existing systems or designed into new streets, which may serve as emergency floodways. The company says siphonic flow also self-cleans pipes. It envisions wastewater/surface-water separation as another use.
- The page cites European flood costs rising from about USD 5.6 billion to USD 29 billion by 2050 and describes the product as relevant to flood-prone cities. Aiwell Water says its technology is patented in the US and EU and seeks customers, engineers, investors or partners for further development and international expansion. The listing marks availability as “Soon available.” Links to UN goals 6, 11 and 15.
