Rain Water Harvesting

Rainwater harvesting brings many benefits by reducing the consumption of drinking water. In addition to significant savings on the water bill, your company actively participates in the preservation of natural resources and the environment .

Informations technologiques

These savings come in particular from the limitation of withdrawals from groundwater, and therefore the expenses necessary for the treatment of drinking water (less energy devoted to pumping, to the drinking water treatment plant and to transporting the water).

A rainwater harvesting facility is a system for collecting and storing rainwater for later use. The implementation of a specific installation, which may vary in its complexity depending on the end use, is necessary to meet this objective. REENIU France offers solutions adapted to your context, aiming to include the recovery of rainwater and its use in a global logic of economy and ecology.

Rainwater harvesting can serve different complementary purposes.

  • Watering the company’s lawns (mainly in summer when water is restricted), washing company car fleets;
  • Supply of a “rain garden” purifying the water before infiltrating it into the water table (possibly at the outlet of an overflow from a recovery tank)
  • Supply of staff toilets (whose gray water could possibly be purified by natural lagooning or filtering marshes;
  • Various cleaning (floors, exterior, etc.).
  • Supply of industrial water circuits, eg machine cooling circuit.

The recovery of rainwater is subject in France to strict legislation which imposes certain characteristics to the system to prevent any health risk.
REENIU France and its partners guarantee you an installation that complies with French regulations, with the issuance of a health and maintenance booklet at the reception of the site, then the realization of an after-sales follow-up.
