Waste and exemption and other "savings" won't make up that kind of shortfall. I've heard that call many times. Like "line by line audit," it rarely if ever reveals anything useful. One never sees the wisdom behind spending money. Just how it got spent. If I recall correctly it's the sewage costs that are the major part of the budget. If you believe charges matching expense, that's where charges need to go. Now wait for the uproar when that happens. The UNDP guys in Vietnam i met back in the day could probably help out our 3rd world system on humanitarian grounds.
