The water is poured (passive). Somebody pours the water (active).
The water is to be poured (passive). Somebody is to pour the water (active).
The first sentence, which is the present simple passive, shows that somebody always, regularly, or as a routine pours the water.
The second sentence is also in the present passive form, but it means that somebody intends or it's necessary for him to pour the water. It's indicative of an action that is going to happen.
