INNovative Energy Recovery Strategies in the urban water cycle-INNERS Drs. Katrien Bijl Project manager Water Board Groot Salland Zwolle, The Netherlands 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
Upcoming challenges water and energy • EU 2020 regulation • Fossil fuels will become scarce; we need to minimise our energy use and maximise the reuse of energy 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
Energy in the UWC Drinking water supply Wastewater chemical and • transport, treatment, distribution operational energy • collection and treatment • 0.48 kWh/m 3 • 0,16 and 0.9 - 10 kWh/m 3 , resp. Domestic water use • cooking, washing, cleaning • > 50 kWh/m 3 (data by Olsson, 2011) thermal energy 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
The INNERS project • 11 project partners … from 6 countries in NWE • … with one common goal: Creating a more sustainable urban water cycle by collecting, reuse and saving of energy Project duration: April 2011-December 2014 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
INNERS activities • Data collection and modeling studies to understand the working of the urban water cycle in terms of energy. • Demonstration projects thermal energy. • Demonstrations projects operational and chemical energy. • To inspire technical specialists and policy makers. • To identify legal and organizational barriers for implementation. 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels

Thermal energy recovery • Sustainable swimming pool by using heat from waste water • Using heat from sewers for heating households/ public buildings • Implementation and operation of a local heat grid at a WWTP • Heating and cooling of residential properties by using the storm water system 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
Chemical and operational energy • Research on the separate collection of waste water streams; new sanitation concepts • Implementation of a deammonification technology at a WWTP 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
Benchmark study North West Europe • Investigation and evaluation of the energy consumption and production at waste- water treatment plants • Derivation of a European guideline “Energy at WWTP” 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
How to continue? • INNERS is a European approach to improve the energy balance of the urban water cycle. • The demonstration projects are work in progress, first results will be available the end of 2012. 8 th EWA Brussels Conference, 30 October 2012, Representation of the State of Baden-Württemberg Brussels
