Work Package: Drinking Water Consumption Management


The daily overall water consumption of citizens supplied by the Isfahan Water and Wastewater Co. is around 250 litres per person on average (including commerce and industry as well as losses caused by leakages). In order to design adequate measures for reducing household water use, the customers’ consumption patterns need to be identified. The definition of countermeasures requires information on the exact time water is used, the amount and for what purpose.

Project Activities

Within this work package the consumption patterns of selected households are tentatively measured and water saving potential is identified. Using the DEMAPLAN software, gathered data are analysed and strategies for adequate consumption management are designed. DEMAPLAN prognosis models also allow for deriving starting points for a demand-orientated drink water supply.

Initial measurements were successfully taken in more than 50 households in Kashan, and analysed. The activities are now extended to further towns in the catchment which differ considerably with regards to their climatic conditions and therefore presumably also their water consumption patterns.

The work package involves the development of a training module for water consumption management.

Expected Outcomes

After dependencies and water consumption patterns are understood, locally adjusted water consumption strategies are developed using prioritized measures. The training module is offered by the German-Iranian Competence Center for Water and Wastewater Management (GICC).
