Colorado water providers facing a shortfall of 163 billion gallons are turning to a long-ignored resource: wastewater.
They’re calculating that, if even the worst sewage could be cleaned to the point it is safe to drink — filtered through super-fine membranes or constructed wetlands, treated with chemicals, zapped with ultraviolet rays — then the state’s dwindling aquifers and rivers could be saved.
Colorado officials at work on the first statewide water plan to sustain population and industrial growth recognize reuse as an option.
