Water interdependency stress-tests




No product nor service exists without water input. In a world that can no longer take ample, secured and unpolluted water supplies for granted, we help our clients to manage their water risks to reduce proactively their costs and exposures and/or not miss any wastewater reuse opportunity. We take into account domino effects of interdependencies and externalities such as:

  • Water volume: flood occurrence, water scarcity, upstream storage, etc.
  • Water quality: temperature, contamination, etc.
  • Water infrastructures: acquisition of water rights, digital monitoring, etc.

Examples :

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

Water health nexus
This situation can put more pressure on water overuse by other cotton growers and/or water and soil pollution by textile producers using chemical products but not guaranteeing related wastewater cleaning.

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 W2AREX® solution bringing benefits and returns for all market participants.

The Water Footprint (see ISO 14046) measures the consumption and contamination of freshwater resources. A cotton T-shirt has an average water footprint of 2’700 liters (www.waterfootprint.org). Clean technologies can be used thanks to the trader’s purchase commitment for treated effluents footprint via its request to deliver treated wastewater for irrigation as per ISO 16075 to his supplier. Positive domino effect of secured sourcing : treated wastewater, improved access to sanitation, dignity and energy provided to the cotton farming area.
In addition to more reliable sourcing, the bio-refineries infrastructures can also be interesting for commodity traders or finance looking for sales via the allocations of the dividends due of wastewater valorization to wastewater suppliers.
More generally, decentralized treatments of sludge can generate renewable energy and fertilizers. Treated wastewater buffer stocks can also be used as energy storage and/or for insurance purposes (e.g. fires, weather/parametric risks). Investors, such as pension funds can manage water interdependence risks by investing in solvent wastewater treatments and get related dividends via our W2AREX platform.

Water Footprint

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

Water Impact Index

Prana treated wastewater is allocated according to the water exploitation index and/or in priority for basic human needs (e.g. 2000 liter /day/capita as minimum water footprint for dignity with 1 liter water for 1 calorie + water footprint for clothes, housing, etc.).
