Water interdependence stress-tests and domino effects stop-loss

Water Risks

In a world that can no longer take ample, secured and not contaminated supplies of water for granted, we need to take into account:

  • Water volume: flood occurrence, water scarcity, upstream storage, etc.
  • Water quality: temperature, contamination, etc.
  • Water infrastructures: finance, management, safety, etc.
  • Water//Security nexus
  • Water//Energy nexus
  • Water// Food Security nexus
  • Water//Finance nexus
  • Domino effects of interdependencies and externalities

Prana Sustainable Water Diagnose services

  • Benchmarking wastewater value according to context, place, difficulty to treat and related by-products in order to facilitate sales of wastewater resources,
  • Assessing and advising to minimize carbon and water footprints,
  • Water rights acquisitions feasibility.

We help our members to manage their water risks and related domino effects to reduce proactively their costs and exposures. This Strategic Water Interdependence Intelligence service also suggests reuse wastewater opportunities.




Example :

Water energy nexus
Water use for fracking shale gas reduces availabilities for cotton cultivation.

Water health nexus
This situation can put more pressure on other cotton and textile producers leading to health problems and ecosystems contamination with chemical polluters.

Water food security nexus
Water pollution does not recognize any border. In consequence, sea fishing possibilities are reduced. This means that fish e.g. in Africa are becoming more expensive reducing access to source of protein.

Negative domino effects can be cut thanks to Prana Sustainable Water’s stop loss solutions.

Decentralized treatments of sludge can generate renewable energy. Treated wastewater buffer stocks can also be used as energy storage and/or for insurance purposes (e.g. fires). Investors, such as pension funds can manage water interdependence risks by investing in solvent wastewater treatments. Those infrastructures can also be financed by commodities whole-sellers looking for more reliable sourcing thanks to prepaid treated wastewater footprints.

A cotton T-shirt has an average water footprint of 2’700 liters (www.waterfootprint.org). A water management company using clean technologies generating sludge energy can get a solvent water market thanks to the trader’s purchase commitment for treated effluents footprint. At a global level if only 10% of the cotton water footprint for the yearly cotton production of 25 million tons come from treated wastewater, improved access to sanitation and dignity for about 3’424’657people (generating 20l wastewater/capita/day) can be provided.

Water Footprint

Measures the consumption and contamination of freshwater resources (United Nations World Water Assessment Programme).

Water Impact Index

Water footprint indicator that aggregates all aspects of water cycle including water quality and availability in the local environment (Veolia Water white paper).
