Septic System Failures

When a septic system fails, pollutants such as nitrogen, phosphorus, disease-causing bacteria and viruses can end up on the ground surface or in our streams and water bodies. The EPA Homeowners Guide to Septic Systems provides information on properly maintaining your septic system and avoiding costly repairs or replacement. If your septic system is not functioning properly, RCDOH can provide guidance; please call 845-364-3173. Note: RCDOH approval is required for all repairs.

Sewage Overflows

Overflowing manholes are often caused by blockages from wipes, grease or debris that do not belong in the public sewer system. Overflows usually result in untreated sewage entering our streams and waterways. Do not flush wipes (even if labeled as flushable), diapers, rags, etc. down the toilet or pour grease down the sink.

If you see an overflowing manhole, call the local Town or Village since most sewer systems are maintained by the municipality. After hours, contact the local police department.

To report any type of spill, call the New York State Dept. of Environmental Conservation Spill Hotline at 1-800-457-7362.

To report a sewage concern use our confidential complaint form or call 845-364-3173.

Sewage Treatment Plant Inspections

There are 6 major Sewage Treatment Plants in Rockland County. These plants are regulated under a State Pollutant Discharge Elimination System (SPDES) permit issued by the New York State Dept. of Environmental Conservation (NYSDEC) and inspected by the RCDOH to ensure compliance with their SPDES permit.

Realty Subdivisions

Realty subdivision review and approval is required for subdivisions of 3 or more lots.
