Sand Filtration

Via ScienceDaily, Dr. James Amburgey, from the University of North Carolina at Charlotte, has developed an inexpensive and low-tech way to treat water using sand. According to Dr. Amburgey, all that is needed to create safe drinking water is PVC pipe, sand and inexpensive treatment chemicals. Previous technologies have used sand filtration, however, this current…

Falling Demand = Rising Prices?

Out west, the economic and real estate downturn have helped alleviate many of the water shortage problems; however, in Detroit the decrease in water demand has had the opposite affect – decreased usage is resulting in revenue shortfalls, making it harder to fund system maintenance – as a result, rate increases are in the works.…
What Do You Pay for Water?

In the US we spend on average $3.75 for every 1,000 gallons. However, averages are misleading – prices range from $1.30 in Phoenix to over $7.70 in Columbus Ohio. This map below shows relative pricing for the 30 largest US municipalities. Take a look at Florida (Miami $1.60) compared to the relatively water rich east…
Water Pyramid

A Dutch company has created the Water Pyramid to help create safe, clean drinking water in tropical and developing countries. While traditional reverse osmosis systems are expensive to build and use a considerable amount of energy, the Water Pyramid uses the sun as its primary energy source and has low operational and maintenance costs. The…
Engineered Osmosis

Researchers at Yale have developed a water purification system that uses one-tenth the electric energy of conventional desalination systems.
