  • The Rising Cost of Water

    There's a common economic paradox about the price tag on drinking water and value. Our current economic climate places prices on things predicated on scarcity and value. Water pricing is now more widespread, with the dual goal of expanding supply and encouraging more responsible use. So long as water remained abundant, the cheapness of drinking water is not likely to change. However, the price of ...
