Reuse Opportunities
 Reduce Water pollution
 Increased water demand:
population growth and
water for industry
Public Parks
Cooling water for power
plants and oil refineries
 Improving public perception
 Avoids costly import water
 Usually a single source of
supply
Processing water for mills,
plants

 TMLDs / Nutrient load caps
 Provides local, climate-
independent, sustainable supply

Abengoa Synergies on water reuse
Approach
Methodology for
identifying and
quantifying
Economic impact
Goal of matching
the level of
treatment
- GHG emissions reduction
- Environmental cost, non pollutants
discharge
- Aquifer Yield Reductions

Indonesia, China, South Africa; OECD, Organisation for
Economic Co-operation and Development; ROW, rest of

demand and does not consider rainfed agriculture.

Amount of energy required to provide 1 m3
water safe for human consumption from
various water sources
Lake or river: 0.37 kWh/m3
Groundwater: 0.48 kWh/m3
Wastewater treatment: 0.62 – 0.87 kWh/m3
Wastewater reuse: 1.0 -2.5 kWh/m3
Seawater: 2.58 – 8.5 kWh/m3

the distance the water is transported or the level of efficiency,
which vary greatly from to site.

Water reuse contributes to reduce cost:
Water Reuse is not always
a burden, but an economic
opportunity
