Rockland County Sewer District No. 1 - Protecting the Environment

sewer_backhoe.jpgThe District primarily services the Towns of Ramapo and Clarkstown and several parcels in the Town of Orangetown. The District operates and maintains the major interceptors and pumping stations in the system and all sewers within the Villages of Spring Valley, New Square, Hillburn, and Sloatsburg.  The Towns of Ramapo and Clarkstown maintain most of the 8" diameter sewers. The District's wastewater treatment facilities are located in Orangeburg and Hillburn, New York.

Rockland County Sewer District No.1 (RCSD#1) was formed in 1963. The RCSD#1 primarily services the Towns of Ramapo and Clarkstown, and RCSD#1 currently operates and maintains the major interceptors and pumping stations in the system. The wastewater treatment plant was originally constructed to treat 10 MGD. Development in Rockland County resulted in the expansion of the treatment facility to 28.9 MGD in the mid 1980's.

In 2000, the District's Board of Commissioners and the Rockland County Legislature extended the Rockland County Sewer District boundaries to provide sewer services to the Villages of Sloatsburg and Hillburn and a portion of the Town of Ramapo at the request of such municipalities. The provision of sewer services to these municipalities required the construction of a 1.5 million gallons per day advanced wastewater treatment plant (AWTP), sewer lines, four pump stations, and force mains. At this time, the AWTP and the pump stations are operational, sewer construction is complete in the Village of Hillburn and a portion of the Village of Sloatsburg, and homes are connecting. 

Statement Regarding Odor

January 24, 2023

Good Afternoon,

You are receiving this email since you have reached out to the Sewer District with regards to odors. By this email and future emails, we are attempting to keep you informed of what is occurring at the wastewater treatment plant that could potentially cause odors. I will be sending these emails out weekly until the primary digester is fully back online and acclimated and then bi-monthly thereafter.

As an update, over the past few weeks, the Sewer District has had no issues that would cause odors to the neighborhood from our wastewater treatment plant in Orangeburg. Additionally, our odor control construction project is proceeding. As we proceed, the Sewer District will operate the facility in a manner that minimizes odors to our surrounding community. Temporary odor control units will be put in place for critical areas during construction. Construction is expected to be completed in Spring 2024.

By this email, I would also like to request that if you wish to file odor complaints, please contact us directly. The best way for us to mitigate odors in real time is if we know about them in real time. Of course, you also are free to contact the Department of Environmental Conservation. The DEC forwards complaints to the Sewer District and they cannot respond to odor matters right away. You may email us at This email is monitored during our normal business hours Monday to Friday 8 AM to 5 PM excluding holidays. You may also call us at 845-365-6111. This phone number is monitored 24 hours per day 7 days a week. Please leave a message if no one picks up. We will also be placing these email updates on our website at

If you do not wish to receive these emails, please reply to that effect and you will be unsubscribed.
