Steve Hiltner: Where Princeton’s Wastewater Goes
When Hurricane Sandy hit, Princeton’s wastewater treatment plant lost power like everyone else. That’s a big deal, because sewage doesn’t miraculously stop flowing, and a powerless treatment plant means 13 million gallons of raw sewage a day pouring straight into the Millstone River.
Fortunately, the Stony Brook Regional Sewerage Authority, as it’s properly called, was able to get 9000 gallons of fuel oil per day trucked in to run backup generators–not easy when trees were blocking roads and fuel oil was scarce. Also fortuitous, the hurricane brought the Princeton area relatively little rainfall with the high winds. Heavy rains would have seeped via groundwater into aging sewers, adding substantially to the quantities of wastewater the plant had to process while it was running on backup power.
