Entry of monthly domestic demands

Domestic demands form the largest portion of municipal demands. They are based on assumed population numbers.

In case there is a strong seasonal variation and you are knowing its pattern you have the possibility to enter monthly data.

Attention: If you entered yearly data first, the same figure will be entered for all months. This facilitates data entry. However, if you enter yearly data after the monthly data, all monthly data will be overwritten!

Same as for yearly data, the following data area available for monthly data entry:

Demand (l/capita/day) Domestic water consumption per capita and day for the reference year. The billed monthly amounts of water for that year are shown, but can be edited individually.
Sudden increase/decrease
Change of absolute number , e.g due to network rehabilitation (change from tanker supply to network supply)
Yearly increase/decrease (%) E.g. due to raising standards of living

For entry of Yearly increase/decrease ,the button   Keep for Following   is greatly facilitating data entry. The same value will be written to all following years. However, editing of the later years is always possible.

Use the top bar to navigate between the individual time steps.
