Here's a simple water jug I modeled based off an image I saw on Google.

It was more of a practice to get the right material. I used Cycles to render it.

The rough part of the plastic is all procedural texture, so it's a very low-poly model.

I used an HDRI for the lighting, which is packed in the .blend. But if that doesn't work, it's also in the actual folder.

More about it, including the node setup can be found [on my website here.](http://davidzerba.wordpress.com/2013/11/30/resource-water-jug/)
