Answer 1

Well, first of all, your question is too vague.  Do you mean storm water or do you mean sanitary water?  Storm water is from surface flow of storms and includes water runoff from lawn watering, car washes (if not installed correctly), and other non-point discharges.  Sanitary includes our kitchen sinks, our toilets and our bathtubs and laundry, for example.

In urban environments, storm water is treated in either detention or retention basins.  The water is filtered through a series of means before filtering through the soil.  There may be mechanisms used to clean out oils, etc by swirling the water  (aqua swirls) or some other means (gravitational or colloidal separation) before it goes into a sediment forebay and then into the basin.  

Sanitary water is cleaned in treatment plants via a series of filtration, separation and chemicals, usually.

In less "developed" areas, septic systems may be used to handle sanitary water/debris.  This involves a septic tank and a septic field and can only be used where the soils are conducive to allowing water to filter through the soils.  Clay soils are not good for septic systems.

As far as the word "basin" ... a basin is  like a bowl.  Your kitchen sink can be thought of as a basin.  It is simply a "bowl" or depression in the soil/land/topography.

Prarie S seems to know their stuff and is in the water or wastewater field I would suspect.

One detail I might add is that both urban and rural have one thing in common. They both rely on microorganisms to feed upon and breakdown organic wastes. Give these "bugs" food(organic waste) and oxygen, they do a very good job of decomposing waste and rendering it safe.

Urban treatment goes a step futher and treats the final product with disinfectant(chlorine).
