WASTE WATER City officials in Portland, Ore., said last week they will drain 38 million gallons of treated water into its sewage system after a teen was caught urinating in the reservoir. Officials said the water was ready to be distributed into the city's drinking water system when the incident happened. While acknowledging that the urine poses no real health threat, Portland Water Bureau administrator David Shaff said customers expect clean water and that's exactly what the city intends to deliver. The 38 million gallons of water will be drained into the sewage system instead, and replaced with new treated water. Shaff said the city has plenty of water, and replacing the 38 million gallons will be easy. It's the second time in recent years that the city has done it. In 2011, the city drained 7.5 million gallons after a similar incident. It's a tremendous waste of a precious natural resource, even though replacing the water won't be difficult in Oregon. It's too bad the city couldn't have found some productive use for the water, perhaps for crop irrigation or something similar, rather than simply draining it into the sewage system.
