WASHINGTON — Sewage from the Piscataway Wastewater Treatment Plant that had been spewing into a creek, then a retention basin, is now being piped into a treatment plant, marking a major milestone in repair efforts.
However, a full repair is still at least a week away.Â
A 52-year-old cast iron pressurized sewer main at the plant, in Accokeek, , causing about 3.35 million gallons of untreated wastewater to overflow into the Piscataway Creek, the Washington Suburban Sanitary Commission said.
Crews were able finish a second set of temporary piping and pumps early Wednesday, allowing the sewage to bypass the break and be pumped right into the treatment plant. A third set of temporary pipes are being installed as well.
It took some time to get to the break; it was under a concrete-encased structure that also had high-voltage lines. Those lines had to be de-energized and moved.
The replacement pipe is expected to arrive Friday and will take at least a week to install.
The pipe break had no effect on drinking water, the WSSC said; the water and wastewater systems are separate.
