I have lived in Oakland Township since 1994. The sump pump in my basement receives water collected through the drain tile around the perimeter of my foundation. I am now on my third sump pump. The previous two stopped working, I assume after burning out from being overloaded with iron feeding algae growth. I have heard it referred to as Microbial Iron. I am attaching two photos. One shows my sump pump last July after I noticed it wasn't working. I pulled it, and cleaned it with a hose spray nozzle. It worked for a while, but failed again in April and could not be restored to operating condition even after extensive cleaning. The motor would hum, but it wouldn't spin. At that point I felt I had no option but to buy a new sump pump. The other picture is of the back flow check that I removed and cleaned at the same time last summer. My question: Is there some product, herbicide, etc., that I can acquire and use that would prevent the algae from growing. I considered, but ruled out, adding a small amount of chlorine bleach every week or so. My sump pump discharges to the subdivision's stormwater system which then flows to the detention pond in the middle of the subdivision. The pond is a neighborhood amenity with fish, turtles, frogs, etc. Any help you may be able to provide would be greatly appreciated. Thank you. Michael Tyler
