Rainwater harvesting and use

Faced with ever-dwindling water resources, using rainwater represents a responsible choice. Rainwater is a sustainable resource that can be harnessed in many ways to reduce drinking water consumption and save money.

Implementing a rainwater harvesting system helps achieve environmental goals. This measure aims to introduce an ecological and responsible alternative to water use.

Questions to ask yourself before starting your project

  • What is the current drinking water consumption in your company?
  • Is there potential for using rainwater (e.g. toilets, irrigation, cooling etc.)?
  • Are there enough water catchment areas, such as roofs?
  • Do you know the nature of roofing materials, as well as the condition of gutters and downpipes in the catchment areas?
  • Are there spaces to accommodate the water storage facilities?
