Sources said even though there are only puddles of water in the basements of towers 1 to 9, two basements that lie under the towers 10 to 34 are still waterlogged.
‘‘We keep pumping out water, but it oozes out through the soil over the basements. Till this soil, put up for plantation, does not dry up, the basements will continue to face problems of water stagnation. Since the basements are at a lower level than the Yamuna, water had entered during the flooding,’’ said an official.
MCD officials claim they are spraying antilarvae chemicals in the basements but it may not be much help. Said an official: ‘‘We keep spraying anti-larvicide in the basement but with water being pumped out continuously, the entire purpose is defeated.’’
Added Dr V K Monga, chairman of MCD public health committee, ‘‘We are taking all precautionary measures to prevent breeding. Fogging is being carried daily and our staff is working to drain out water from the basements.’’
Experts said that damp basements pose a health risk. Said Dr Bir Singh, head of community medicine at AIIMS, ‘‘The subsoil water collected in the basement can be an ideal space for mosquito breeding. It can cause vector-borne diseases like dengue and malaria.’’ He added mosquito breeding is common on the Yamuna riverbed.
Sources said the state government has now approached Delhi Metro Rail Corporation (DMRC) for assistance in draining out the water. ‘‘We have received a request. Water is seeping into the lifts. We have already worked out a plan for it,’’ confirmed a DMRC spokesperson.
