When you flush the toilet in Allegheny County, chances are that the waste ends up at a facility just up the Ohio River from the McKees Rocks Bridge.

To track the waste's path from one's toilet to the Allegheny County Sanitary Authority, people can use Flush.It.  This interactive map directs users to type in an address that’s within the ALCOSAN service area. After several seconds, a bright turquoise line appears, tracing a flush's route.

It’s back-to-school time in the region, and the Allegheny County Sanitary Authority, better known as ALCOSAN, is highlighting its role in the classroom.

The sewage and water treatment facility isn’t something automatically linked with schools, but for more than a decade, the authority has done educational outreach.

One-tenth of an inch of rain over an hour is all it takes for the region’s sewers to overflow.

That’s according to the Allegheny County Sanitary Authority (ALCOSAN), which has already issued two Combined Sewer Overflow (CSO) alerts this season.  The Authority is hoping that as the river recreation season takes hold more recreational users will take note.

State environmental officials have granted a request to give the city of Pittsburgh and Allegheny County more time to include more "green" solutions to the region's sewer system problems.

The antiquated sewers overflow during heavy rains because storm drains are tied to sewers in a way no longer permitted under environmental laws.

The department said Monday that it will provide an 18-month extension to a March 30 deadline for a plan to fix the problem.

Allegheny County Controller Chelsa Wagner Wednesday threatened to take four county agencies to court for refusing to comply with her requests and delaying audits launched by her office.
