City Alliance ’People. Sanitation. Cities’

is an interest group and a community of practitioners of cities and associates that are implementing integrated sanitation approach (ISA) for the management of urban waters.


is to promote-essential public services according to Sustainable Development Goals and the New Urban Agenda.


is to strengthen capacities of cities in order to support them to implement sustainable system solutions for the management of urban waters with particular polycentric urban planning focuses on the policy framework of sanitation planning for the whole city area. There, the cities are supported in finding approaches and concepts to combine different topics (wastewater, drinking water, waste, stormwater, sludge) into their planning as well as to find ways of communication between different departments and with different stakeholders (civil society, private sector, etc.)


  • Form an internationally linked community of practice of cities and associates on integrated sanitation.
  • Communicate and bring forward the interests and needs of cities towards national decision makers and regional stakeholders related to the application of system solutions.
  • Promote system solutions as a contribution to the Sustainable Development Goals and the New Urban Agenda towards local, national, regional and international stakeholders and;
  • Establish a regional knowledge platform and exchange network



Integrated Sanitation Approach (ISA)

It provides tailor-made system solutions for specific parts or districts of a city regarding the management of urban waters. Thus, considering the particularities of local conditions and their individual sanitation needs and demands, specific instruments, methods and modules are selected and applied as system solutions
