Co-composting unit of the sludge at the Orcières sewage treatment plant
Composting directly on the SITE of the STEP of SMTB Champsaur proved to be the most suitable solution following the prospective and financial study. The recovery of the sludge will be carried out, in particular for the re-vegetation of the ski slopes. this facility is particularly suitable for situations where the temperature difference between winter and summer may be extreme.
This station treats nearly 1,750 tons of sludge per year. It will retreat the effluents of the Step of the communes of Laye, Saint-Bonnet, Orcières and Chabottes.
