Fixing A Source Of Sewer Corrosion
Today’s underground sewer infrastructure is the result of more than 100 years of investment. In the U.S., for example, the sewer system is now valued at an estimated $1 trillion. But that investment is under a chemical threat from sulfide-induced concrete corrosion, according to a research report. The problem is largely preventable by eliminating sulfate—the source of the sulfide—from water-treatment operations, the study’s authors say.
The sewer sulfide problem has been around since sewers were . . .
