LTA seals drains on bus stops ahead of mosquitoes' peak breeding periodBus stops will no longer be built with drains on their roofs.
This, after it was found that the drains can be breeding grounds for mosquitoes.
The Land Transport Authority will also be sealing the drains on all 623 bus stops by next month ahead of the Aedes mosquitoes' peak breeding period.
By installing plastic covers before waterproofing them, it is hoping to prevent the 10-centimetre deep drains from getting clogged by fallen leaves and gathering water.
It costs about $400 to seal a drain, compared to $10,000 to have it removed.
Even after the drains are sealed, it said it will continue to check the bus stops once a week for mosquitoes.
The LTA was fined by the National Environment Agency (NEA) last year after two bus stops were found to be breeding sites for mosquitoes.
Since the beginning of the year, NEA found Aedes mosquitoes at six bus stops.
More mosquitoes breed between June and August when the weather gets warmer, and over the last three years, this has caused the incidence of dengue fever to increase by 35 percent. - CNA
