Mission Statement

The IWA / IAHR Joint Committee on Urban Drainage (designated hereafter as JCUD) and its activities are described in three other companion documents :

  • The 'JCUD statutes',
  • The 'JCUD collaborations' and
  • The 'JCUD account rules'.


Since its creation in 1981, the IWA / IAHR Joint Committee on Urban Drainage (JCUD) has been operated jointly by the International Water Association (IWA), as the Specialist Group on Urban Drainage (SGUD), and the International Association on Hydraulic Engineering and Research (IAHR), as the Technical Section on Urban Drainage within the Technical Division II “Applied Hydraulics”. This joint oversight has been established to emphasize and promote effective interactions between experts on hydraulic aspects (main focus of IAHR) and on water quality aspects (main focus of IWA); such aspects are intrinsically inter-related in the field of urban drainage.
