It Smells!

Aiyoo, it smells! I won't be complaining if the smell is nice, but this pong is terrible. Almost at all the eating places in town, the drain beside is dirty and smelly. Near Hawker Centres (e.g.Jalan Tun Razak, the Stadium) , roadside stalls(everywhere), even near 'clean' restaurants (e.g.KFC Jalan Putra). Just go to any corner where there's an eating place and always the smell will hit you first as you get out of the car. It is easy to see why it like that. Dirt and washings from the kitchen sink goes straight to the drain. They are supposed to be channeled to the sewerage system right? I supposed they are not, hence the foodstuffs etc from the kitchen sink get trapped in the drain and that results in the smell. Surely people concerned know if this problem - the authorities, the eatery operators, the public - but so far nobody is doing anything about it. The solution is quite obvious but nobody cares.
