well, water is a resource, it cannot be produced though. There is approx. the same amount of water on earth today as there was when the dinosaurs were roaming it. Renewable resources are those that can be produced and reproduced when they are needed.
Trees are a renewable resource because we can plant them and they grow, so if we keep planting them we will still have trees. But if, somehow, all the water dissappeared off the face of the planet we would not be able to make any more because we don't have the means of producing water from its two elements: hydrogen and oxygen.
So no, water is not a renewable resource, it IS, however, a Recyclable resource.

Yes, because of rain.
When water rains down or comes down as sleet or snow it eventually makes it way to the ocean. Along the way it travels through fresh water streams, lakes and rivers to the sea. At that point it has picked up a lot of dirt, soil and waste products which makes the sea salty. The salt stays suspended in the water while other stuff falls to the ocean floor or decays away. The salt is a whole range of mineral combinations not just NaCl Sodium Chloride = table salt.
When wind passes over warm water it picks up moisture and this moisture is salt free. So it rains down as fresh water. This allows it to refill lakes, rivers, and streams and to restock the underground water supply.
The earth's ecology is a closed system. What makes water a renewable resource is that it stays in the cycle and it goes from cloud to land to fresh water to sea to cloud again.
The problem is that their is more salt water than fresh water and we are ‘mining’ a lot of the water from underground supplies. We are pumping it out faster than the rain can replace it. With the increasing world population and the increasing need of food to feed them our supply of fresh water is becoming strained. With global warming the climate is changing and rain patterns change. This has caused huge droughts world wide; it is very bad in Australia.

Not so much renewable as recycleable. The amount of water on the planet is pretty constant if you consider the polar ice caps as water.

certainly
It rains......
and collects water into puddles, which evaporate to form clouds and then.....
it rains
