One thing you have to get used to in Panama is the unsteady supply in energy and water. There's been a power outage every now and then. Sometimes after two days, then none for two months. Often enough I probably don't even realize when they happen as the country is pretty decently prepared for it. My router has a battery, I use a laptop and my house has generators that restore power supply withing 5-10 seconds. Several times I just relized there's no more power because of the tremendous noise of the generators.
The water is clean, but in the 10 months being here, this is at least the third time its supply is cut. Once for two days which turned out to be 4 days. While my house has its own tanks, in that four days even it ran dry. But you can prepare. Just get one or two 5 liters containers and you'll be fine.
