Drinking water quality is at risk due to heating of water in pipelines

Municipality is heatproof if

• There are no drinking water routes in heatsensitive places in (the bottom of) the public space.

Measures

• Provide cool routes in public spaces, with plenty of shade and good insulation compared to heating networks in the ground.
• Make agreements with drinking water companies about:
  • The depth of drinking water pipes in the ground.
  • The location of water pipes in buildings relative to the sunny side (south facade).
  • Alternative drinking water supply for extreme situations.

Tips

• Get in touch with the drinking water company and the manager of heating networks in the municipality.
• Make agreements about:
  • The depth of the drinking water pipes in the subsurface.
  • The placement of these pipes in cool routes.
  • Its location in buildings.
  • The implementation of the above agreements and all necessary relocations of drinking water pipes where they heat up too much.
• Draw up an emergency plan for hot periods and the supply of alternative drinking water supplies.
• Work is currently underway to save drinking water through the National Drinking Water Saving Action Plan. The ambitions for drinking water savings are part of the letter to parliament guiding Water and Soil. Also read the research into a possible obligation to use rainwater and greywater in the building. Heat risks are (still) included to a very limited extent.
