Singapore in need of bird bath, please

It's a hot season in Singapore and the demand for water will increase. There isn't any problem for the people, but it creates a big problem for other cohabitants. In any modernized and big cities, water source is never sufficient for the wild (e.g. Birds, squirrel, insects) and semi-wild (e.g. strays) cohabitants because of inaccessibility to (or danger of) the drainage system for water, particularly birds.

In other countries, bird baths are made available for birds (who are most affected by heat as they are most exposed to direct sunlight). The accessibility to water source is crucial for their survival, especially in hot weather.

In Singapore, bird bath is close to nil. The reason being, stagnant water breeds mosquitoes and among them are pathogen carriers, e.g. dengue or malaria. To instal water source, an innovative means of filtering and killing off mosquitoes larvae will be needed, but lacking. That is why, sadly, there isn't any available water source for birds, squirrels, butterflies, bees, strays etc. over here.

Surely it isn't difficult to design a way to provide water to the wild or semi-wild without the mozzies.
I wonder when will the day come when we can see birds, butterflies, dragonflies, bees, squirrel, perching onto baths for water, surrounded by gardens? It would be beautiful.
