In relation to the complaint by the Asociación de Naturalistas del Sureste of a discharge of waste water from the sewage system of La Manga del Mar Menor, in the municipality of San Javier, into the Mediterranean Sea, the Councillor for Public Services, María Dolores Ruiz, states the following:
This is an outfall (the only one remaining of the six that San Javier had, corresponding to pumping station no. 6) shared by the municipalities of San Javier and Cartagena, which has been inactive for years as neither municipality has had to use it in recent years. The outfall is a necessary infrastructure that would only be used in emergencies, although thanks to the good functioning of the WWTP it has not been necessary to use it in recent years.
The current situation with part of the outfall pipe on the surface is due to the entry of air due to the looseness of the outlet valve, which will be replaced in the next few days, as due to its age there is no replacement and the part has to be done by hand.
María Dolores Martínez explained that last week the San Javier Town Hall contracted the services of divers to temporarily ballast the pipe to the seabed until the new valve is ready, which will hermetically seal the pipe, preventing it from rising to the surface.
The work of the divers consisted of removing the air so that the pipe could be placed again on the seabed, removing the screws from the upper part and, due to the pressure, expelling any debris that might have adhered to the pipe, but in no case would wastewater be discharged, because the outfall would only be used in emergency situations, which have not occurred in recent years.
The divers will dive again this afternoon to replace the screws with others of a larger calibre and prevent them from jumping out due to the pressure, to ballast the pipe as a provisional solution until the valve is ready and can be replaced in the next few days.
María Dolores Ruiz reminds us that this work is being carried out jointly with the Cartagena Town Council because the valve is in San Javier but is remote-controlled from Cartagena in case it should ever have to be evacuated, although it has not been done for years by either of the two Town Councils.
As for the quality of the water, the Councillor for Beaches recalls that according to the system of sampling and water analysis that has been carried out throughout the summer until the last known result dated 22 August, the quality of the water for bathing is “excellent”. The data from the analyses carried out by the General Directorate of Public Health can be consulted on the Náyade portal, which depends on the Ministry of Health.
