The City Corporation on Friday submitted before the Kerala High Court that there was not even a single instance of death due to dengue fever in the city. It also said chances of mosquito menace this time in the city is low, as all drains under the corporation have been cleaned. In an affidavit, Kochi Corporation Secretary P M Francis submitted that there were hardly 75 suspected cases reported in the city. However, the diagnosed cases are quite few. The Corporation submitted that it was concentrating on the destruction of mosquitoes at larvae stage at the breeding place itself by spraying larvicide. The breeding places of mosquitoes are usually drains and other waterlogged areas. So, in order to eradicate mosquito, each division of the Corporation has been divided into six day blocks and insecticide is sprayed in each block regularly. 275 persons have been employed by the Corporation for anti-mosquito drive. It also submitted that for eradicating adult mosquitoes, fogging was also done periodically. As fogging is likely to invite health hazard problems, it is usually undertaken only during high breeding season. Other cleaning works like removal of waste, drain cleaning, salt water flushing in drains, removal of vegetation, providing nets to vent pipes of septic tanks and sealing of septic tanks etc are also undertaken by Corporation staff in systematic manner. It pointed out that the construction work of drainage for eradicating water-logging problem had to be abandoned by the Corporation halfway due to opposition by certain persons. However, almost all drains in the corporation limits have been cleaned and waste removed from the drains. Hence, the chances of mosquito breeding in the city is very low. The Corporation is collecting around 180 tonnes of solid waste from its limits everyday and it was being processed at Brahmapuram plant, the affidavit pointed out. The affidavit said the government had granted permission for setting up a sewage effluent treatment plant at Mundanveli. However, objection had been raised against the plant. Besides, the High Court had already passed an interim order. As a result, the Corporation could not proceed with the construction of the plant. The cleanliness of the city could be maintained only with the cooperation of the public. The Corporation has been arranging awareness programmes and classes for the public about cleanliness.
