And in severe cases, sanitary sewer overflows result in regulatory fines.
There are various treatment processes that are used to remove iron and manganese from ground water for potable water supplies. While there are various less common treatment methods used (such as ion exchange and ultra-filtration), most treatment systems for iron oxidize the ferrous state of iron to a ferric state so the solid particles can then be filtered out.

One afternoon at a waste water treatment facility, an alarm goes off when the water pressure gets too high in one of the tanks. The alarm is set at priority level 4, which means “critical,” but it doesn’t stand out because almost every other alarm at the facility is set at that level. Besides, the operator can’t acknowledge it right away because he’s dealing with several other alarms that went off a few minutes earlier – which he doesn’t yet realize are just “nuisance alarms.”
When it comes time to update, it's a prime opportunity to consider switching over to new software that offers improved functionality instead of dumping more money into just keeping your existing software up-to-date.
