Commercial bottling can dominate the same aquifer that supplies local taps. At Vittel, Nestle Waters accounts for roughly 80% of the deficit of an overdrawn aquifer, and illegal boreholes and treatments led to a 2 million euro settlement in 2024.

Turn flood-control drainage into water supply with spreading grounds, injection wells and green infrastructure that recharge aquifers, financed by a hypothecated parcel tax on impermeable area so revenue scales with the pavement causing the runoff.

Pump shallow groundwater in winter into lined open reservoirs so farms substitute stored water for summer abstraction, tied by protocol to agroecological commitments. Contested: supporters cite modelling and court validation; opponents cite evaporation, resource capture, and mala

User-run bodies (irrigator communities, water tribunals, village assemblies) allocate scarce water and resolve conflicts cheaply, quickly, and by peers. Commons survive when boundary rules are clear and enforcement costs stay near zero — institutional design, not technology.

Villages build and own earthen johads, contour trenches, sand dams, infiltration canals and ponds with NGO facilitation. Cheap per structure and compounding at catchment scale, but success hinges on hydrogeological siting, maintenance institutions and demand rules.

Measure W, the Safe Clean Water Program, passed in November 2018 with ~69% voter support, creating a ~$280M/yr parcel tax on impermeable area, hypothecated to stormwater capture and quality projects. By 2024 more than $…

The Deux-Sevres program comprises 16 winter-filled substitution reservoirs built by the Coop de l'eau 79, with approximately 70 percent public funding (total program cost figures around 76 million EUR circulate but are…

The Tribunal de las Aguas de la Vega de Valencia has operated continuously for over 1,000 years since al-Andalus. Every Thursday at the door of Valencia cathedral, eight farmer-judges elected by peers from nine canal co…

Kitui County hosts over 1,000 sand dams built since the 1990s across seasonal riverbeds — the world's densest concentration — making it the best-documented test case for sand dam performance at scale. Independent survey…

Amunas are pre-Inca infiltration canals in the Peruvian highlands that divert wet-season streamflow onto permeable slopes, where water infiltrates and resurfaces downslope months later, extending dry-season availability…

From 2016 to 2019 the Paani Foundation ran the Satyamev Jayate Water Cup: 45-day competitions in which villages raced to build watershed structures (contour trenches, bunds, ponds) through shramdaan (voluntary labor). P…

Since 1985, Tarun Bharat Sangh facilitated village-built earthen recharge ponds (johads) across Alwar district, Rajasthan. The model requires 25–33% village labor/cash contribution per structure to anchor ownership. Typ…
