Challenges and objectives

The urban water cycle is partially closed and challenged intensively by competing uses and pressures such as:
  • drinking water production
  • discharges of stormwater and treated wastewater
  • combined sewer overflow (CSO)
  • recreational purposes
The objectives for Berlin are to:
  • improve the performance of the sewer and drinking water infrastructure
  • foster public involvement in urban water management
Therefore, several innovations will reduce the environmental impacts of the sewer network. The work will focus on illicit connections, combined sewer overflows and optimizing the maintenance and planning of water wells.

Activities is developing in Berlin the following digital solutions:
  1. an innovative application to support data collection, sharing and visualisation of the operation of drinking water wells
  2. digital solution to track hotspots of illicit connections
  3. new generation of sensors for real-time in-situ bacterial measurements in the river and for Combined Sewer Overflow (CSO) monitoring in the sewer system
  4. an augmented Reality (AR) technology to prove the excellent drinking water quality, encourage tap water consumption over bottled water and raise acceptance of citizens for the necessary investments to tackle infrastructure challenges


The activities in Berlin are in line with Berlin’s new political agenda on digitisation and are actively supported by the following associated partners:
  • Berlin Senate Department for Economics, Energy and Public Enterprises (SENEEP)
  • Senate Department for the Environment, Transport and Climate Protection (SENETC)
