There is an undeniable nexus among water, energy, and greenhouse gas (GHG) emissions, or carbon. A substantial amount of energy is used to divert, convey, treat, deliver, and dispose of water in California. The water sector uses 19% of California’s electricity and 32% of its natural gas. Recent concerns about such emissions and their contribution to climate change have created new opportunities to promote water recycling as a means to conserve energy.
The Tools and the Talent
Soaring prices have prompted many wastewater treatment plants to reduce dewatering polymer use. There are many ways to do this. Some options, such as installing newer equipment, are capital-intensive. Others, such as putting operators in charge of dewatering performance, cost very little but provide excellent results.
A Hole New Problem
Aug. 13 and 14 are days that will live in infamy in Cleveland — or at least for the city’s Water Pollution Control department. During that single 2-day period, thieves stole an astonishing 106 catch-basin covers — that’s 5.4 Mg (6 ton) of cast iron — from the city’s streets, according to Tom Marsales, the department’s deputy commissioner.
Cleveland isn’t the only U.S. city rocked by this latest form of crime spree. Utilities in cities nationwide are reporting a rise in theft. Manhole covers, sewer grates, water meters — anything made of metal that’s not nailed down — are now a target. Philadelphia has lost about 2000 inlet covers so far this year. More than 80 sewer lids and eight fire hydrants went missing in Long Beach, Calif., in 2008; none was stolen the year before. Flint, Mich., has had to replace 400 manhole covers and grates this year.
