Concrete and fast results

Géraldine Bougeard
Director of Vichy aquatic stadium

Since March 2012, we have been recovering calories from gray water to preheat the water that supplies the pools and store the cooled water to wash the filters. Now in terms of water consumption, we are at 50 liters/swimmer against 100 to 150 liters previously.

Olivier Dutrieux
Director of Aqualib' at la Côte Saint André

Very good general opinion, the calorie gain is 230 MWh in 1 year. Very good thermal stability of the pools. In summer we are able to heat to temperature, just by exchanging with Degrés Bleus! And above all technical comfort with less useless presence of technicians in the evening. Possibility to wash more frequently and on demand depending on the filters' needs.

Philippe Martin
Technical Manager of the Nautical Space of Grand Chalon

We are currently at 220 MWh of energy savings and should approach 500 MWh over the year. We have also managed to control our water consumption: From about 55 liters/swimmer to 40 liters per swimmer and per pool.

We are very satisfied.
