Because they add chemicals to kill off all the bacteria and any creatures living in it. But in small enough amounts to be harmless to humans/cats/dogs/whatever else may drink it that's bigger than a spider :)

Collection of rain water through roof catchment rain fall can be collected into a storage tank?
It certainly can; people in Europe have been doing it for centuries. It is usually collected in a large barrel rather than a tank - it's always called a water butt. It is supposed to be used for watering plants during dry spells, but in hard water areas the women have long known that washing your hair in rain-water leaves it softer and shinier than water from the tap. Some people use a downspout diverter to have option of collecting rain water whenever they want to into a container or to run it normally through a downspout drain extension. Another way to collect rain water is by using gutters with rain chains attached instead of normal downspouts. Rain chains work best hung from gutters with a few rain chains positioned evenly along the length of guttering. There are small holes or taps made into the gutter and the rain chain hang from these taps. The rain chain can extend to the ground or empty into a basin to collect rain water. Rain chains add a decorative, visually entertaining and even relaxing touch while functioning to direct rain water into your container. Rain chains are best made of copper and allowed to weather naturally.

What is the process for using animal feces to make fuel?
The process to convert animal waste to gaseous fuel is rather simple. You would compost the feces and collect the fumes released by the process. One way would be to use two barrels. In the first barrel, you compost the feces by keeping it moist and stirring it regularly. You would use the second barrel to collect the vapors released during the composting process.

Can you collect a breyer horse at 18yrs old?
Absolutely! There is no age limit for equine admirers and nothing to be ashamed of. In fact many people, young and older, would rather have a Breyer collection than a live horse that needs food, care and much time. So collect your horses and have fun.
Can you collect gravity?
I am not sure what you mean by collecting gravity. It might be useful to consider an electric field in comparison: You can collect charges, but you cannot collect the field itself. A field will follow the charges around however. In the same way you can collect massive objects (or rather objects with energy), but you cannot collect the gravitational field they 'emit' itself.
