By prefectural order of 30 October 2020, the Community of Greater South Caribbean agglomeration (CAGSC) was given notice to stop the discharges of wastewater into the natural environment and remove the too full to the Cicero ravine which has been disrupting the city center of Basse Terre for several months. By letter of 20 December 2020, the CHBT informed the CAGSC that it had filed a handrail against the CAGSC for pollution at the CHBT. The Gaston Feuillard Avenue network is intended to transfer wastewater originating mainly from the village of Saint-Claude, as well as wastewater collected in the concentrated area of dwellings from Monts Caraïbes to Circonvallation and discharged by a post located on the Avenue. This discharge station, which lacks a hydrogen sulphide removal device, is at the origin of two subsidences in 2012 on the road to Bologna, at the crossroads of Rue Chevalier de Saint Georges and in 2017 near the crossroads of the Bologna road and Gaston Feuillard Avenue. It is almost certain that this infestation is at the origin of this malfunction which can only be corrected by a total diversion of the networks in question. A rehabilitation project had been initiated by the CAGSC and was taken over by SMGEAG.
