Singapore's Storm Drain and Shelter From Rain

Singapore is a tropical country. It rains in rainy season. It rains every season. We are glad of the rain when it drives away the haze. Rain also waters the unattended aloe vera plant on the balcony.
Water prices are going up. Will this drive up prices of other goods, such as coffee in a cafe?

Problem
How do you avoid or divert unwanted rain in Singapore?
What could go wrong?
1 Swimming: You leave swimming until the afternoon and then it rains.

2 Taxis: You postpone calling a taxi until it rains, then taxis are unobtainable.

3 Rain Through Your Windows. All over your computer screen, laptop, mobile phone, office chair, newspapers, right the way from under the window to the far side of the room!

4 Storms trips the electricity. Food such as fish in the freezer, fresh milk in the fridge ...

5 Wet pavements when walking

Answers
1 Swimming Time
Swim in the morning.

2 Taxi Demand
That should change soon with variable pricing which increases costs when demand is high, so only those prepared to pay more take a taxi.

3 Rain: Leave a notice on the back of the front door: Take umbrella; shut windows.

4 Tell everybody how to turn the circuit breaker back on again.

5 Raffles built the five foot ways along the fronts of shops, covering the pavement (Americans say sidewalk).

Finally, some good news: All over Singapore shelters are built along streets between station.
