Ruelisheim Wastewater Treatment Plant

Inaugurated in 1997, this wastewater treatment plant operates using a biological process.

It is designed to treat sewage from a population equivalent to 48,000 inhabitants, with a maximum urban flow of 25,000 cubic meters per day.

During rainy periods, a storm basin can absorb an additional flow of 820 cubic meters per hour.

The sludge resulting from the treatment is then dewatered using a filter press before being composted.
