Orange County Sewer District Number 1

Harriman Waste Water Treatment Plant, located at 72 River Road, is CLOSED TO THE PUBLIC until further notice


Whether you have a private sewage disposal system (septic tank) or you are connected to Orange County Municipal Sewer System, each has the same thing in common: they are designed to treat domestic waste only, human waste, and toilet paper.

This means NO paper towels, disposable wipes, antiseptic wipes, feminine products, petroleum products, paints, paint thinners, industrial cleaners, grease, pesticides, etc. are to be flushed down the toilet.

During the Covid19 State of emergency, as declared by the NY Governor and Orange County Executive, there is a high demand for toilet paper and if not available, paper towels, cleaning wipes, etc.

Despite this crisis it does NOT change the plumbing’s ability to handle non-conforming wastes.  If you are using additional amounts of paper towels and disposable wipes that’s a very good thing to stop the spread.  However, it is equally important to dispose of them properly, in the garbage.

On top of this crisis no one needs the additional headaches of a backed-up plumbing system.
