Water demand

Explanation of the problem

During periods of heat, water supply companies often experience an increase in water demand from agriculture, livestock farming, households, swimming pools, industry, and electricity companies. Because periods of heat frequently coincides with drought, the water demand is further intensified. There are also more peaks in water consumption because, for example, people often irrigate their gardens. For water supply companies, the higher peak demand is not only a problem due to capacity issues, but also because it changes the pressure in the pipelines. Drinking water pipelines are designed for a specific peak. An increased peak demand can lead to lower water pressure and more complaints about brown water.

Note: During hot periods, the demand for groundwater and surface water may also increase. Surface water levels (clearance height and depth) must be maintained for navigation and water quality. As this is more of a drought problem that can occur outside the city, this topic is not further highlighted in the mind map and factsheets.
