Thanks 'Old Man' and 'Administrator' for your knowledge.
Anything to do with rocks and rock formations, minerals, river systems, reservoirs, surface topgraphy and subsurface features/structures are very interesting to me personally. I think most of the water in Vientiane comes from several of the smaller reservoirs north of Vientiane or in combinations of underground reservoirs and may not much so from the Mekong River because of the seasonal fluctuations. I agree with you water is water no matter it comes from.

Okay, thanks for clearing that up. I've never been interested in where my tap water comes from, as long as I have tap water.
The Mekong river must be the main water supply, and underground for homes with wells. Yes, we are still living in the prehistoric age in Vientiane folks.
