  • LifeStraw®

    According to the World Health Organization, 3.575 million people die each year from water-related disease, and 84% of water-related deaths are in children ages 0 – 14.

  • 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…
