Figure 3. Energy use over time with and without optimisation and new approaches in the urban water
cycle; 2008 as reference point (100%)
Regarding the time scale, a differentiation can made between the low-hanging fruit (< 2010),
optimisations/technological innovations (< 2015-2020) and a paradigm shift/new concepts (<
2030).
In a optimal timeframe, the supporting activities by the GWRC members of step 1 (picking low
hanging fruit) with the project Energy Efficiency in the Water Industry: A Compendium of
Tools, Best Practices and Case Studies) and the development of the Toolbox of integrated
Performance Evaluation would start directly.
As next action, the discussion on and the development of supporting projects and activities for
step 2 and 3 should be initiated to detail and start the projects needed. The project Revamp
Wastewater Treatment Operations with 20% energy reduction could be considered to coordinate
and complement the present research activities by individual GWRC members and other related
research initiatives (i.e. EU projects NEPTUNE and INNOWATECH). The year 2030 is nearby.
A brief document Water and Energy: a roadmap to the future! that describes the overall goals
and objectives and benefits, the drivers and background of the foreseen projects would be of help
to communicate these activities by the water and wastewater sector as well support the
discussions with possible co-funders of the projects at a national/international levels.
