Attention Notice 108-8 Area: Suffolk County has distributed Access Agreement documents to each homeowner in the 108-8 Area including additional information for signing. Access Agreements must be signed and notarized by the homeowner by May 31st, 2022, before construction may begin.

Mission Statement

The Suffolk County Coastal Resiliency Initiative seeks to mitigate impacts to human life and property, surface waters, and coastal wetlands, associated with onsite wastewater treatment and disposal system failures caused by natural hazards. The Carlls River Watershed Sewage Project will bring together Long Island’s engineering, construction, and consulting professionals to complete this needed coastal resiliency project, post-Superstorm Sandy.



Background

In January 2019, residents voted to approve Resolution No. 905-2018, Adopting Certain Findings and Determinations and Issuing an Order to Extend the Boundaries of the Suffolk County Sewer District No. 3-Southwest to Include a Separate Zone of Assessment and be Known as Zone A-Carlls River. This vote approved the Carlls River Watershed Sewer Project that will sewer areas in the southwestern quadrant of Suffolk County, including portions of Deer Park, North Babylon, West Babylon and Wyandanch.

Suffolk County obtained NYS and federal post-Sandy resiliency funding that was made available through the Governor’s Office of Storm Recovery (GOSR) to sewer communities along certain river corridors in unsewered low-lying areas along Suffolk County’s south shore that had been inundated by Superstorm Sandy. https://dpw.suffolkcountyny.gov/sccri/

The project sites are:

  • Carlls River Watershed in North Babylon, West Babylon, and Wyandanch, Town of Babylon
  • Forge River Watershed in Mastic, Town of Brookhaven

Reasons for Project Area Selection

Suffolk County evaluated priority areas for new sewer systems based on: (i) substandard septic systems and cesspools, (ii) small lots, (iii) dense populations, (iv) a short depth to groundwater, and (v) short travel times for nitrogen-enriched groundwater to enter surface waters. The data recommended locations along the coastline that are severely affected by sea-level rise, especially during hurricanes. The recommended three priority areas for the installation of new sewage collection systems include Mastic (Forge River); North Babylon and West Babylon (Carlls River); and Patchogue (Patchogue River).

CONSTRUCTION PROGRESS UPDATE

110-2 project area (North Babylon):

Work has commenced and consists of the installation of the sewer pipe below the street and service laterals by the construction contractor, Grace Industries. At this time, you should have received a letter from Grace Industries, explaining the work activities that will be completed. Private property work has also begun throughout the 110-2 region (North Babylon) as well by the construction contractor, Pioneer Asphalt and Paving. This work consists of the contractor’s initial preconstruction survey, preconstruction photographs, verification of underground utilities, excavation and installation of grinder pump units (GPU) and sanitary piping as well as the installation of the electrical work by Eldor Contracting.

Homeowner Sewer Connection Sign-Up Sessions were held in March and April 2022.


108-8 project area (West Babylon)

Work on project area 108-8 has commenced and consists of the contractor’s Grace Industries initial preconstruction survey, preconstruction photographs, verification of underground utilities, installation of the sewer pipe below the street and service laterals. At this time, you should have received a letter from Grace Industries, explaining the work activities that will be completed in the street. Once Grace Industries street work is completed, they will commence work in early fall on private properties; work includes site investigations and photographs in the private property followed by excavation and installation of the grinder pump unit (GPU), the new sanitary piping and electrical work.

Homeowner Sewer Connection Sign-Up Sessions were held in May and June.


108-11 Project Area (Wyandanch)

Work on project area 108-11 has commenced and consists of the contractor’s Grace Industries initial preconstruction survey, preconstruction photographs, verification of underground utilities, installation of the sewer pipe below the street and service laterals. At this time, you should have received a letter from Grace Industries, explaining the work activities that will be completed in the street. This work will be followed by the installation of the grinder pump unit (GPU), and the new sanitary piping and electrical work by Pioneer Asphalt and Paving.

Homeowner Sewer Connection Sign-Up Sessions are being held in July and August 2022. Click here for location, dates and times.

Coastal Resiliency

What is coastal resilience?

Providing infrastructure for a community to “bounce back” after hazardous events such as hurricanes, coastal storms, and flooding. Suffolk’s resilience is based on our ability to prevent a short-term hazard event from turning into a long-term community-wide disaster. Our coasts are vulnerable to sea-level rise and heavy storms that can result in flooding.

Post-Sandy coastline damage

In 2012, Hurricane Sandy hit Long Island and over 100,000 homes were deemed severely damaged or destroyed, with another 2,000 deemed uninhabitable. The primary causes of this damage, according to NOAA, were waves and storm surge. Devastation from Superstorm Sandy and the risks posed by climate change and sea-level rise justify bold and continuing actions to dramatically improve coastal resiliency in Suffolk County. Poor water quality, especially from nitrogen pollution, has reached a near-crisis point in many coastal areas of Long Island. Peer-reviewed science has demonstrated a connection between excess nitrogen pollution and the degradation of the coastal marshland complexes that help protect Long Island’s south shore population centers from storm inundation.

How will sewers help?

The most effective solution for nitrogen pollution in high-density communities that have individual disposal systems is the installation of sewage collection and treatment systems. Suffolk County has proposed technically sound, large-scale projects to extend sewers to North Babylon and West Babylon to address nitrogen and pathogen pollution in the Carlls River and Great South Bay. The extension of sewers to this area would be an important first step in a comprehensive effort to reduce nitrogen pollution adversely affecting south shore shellfish beds, seagrass, water quality, and resilient marshes. https://dos.ny.gov/system/files/documents/2020/04/coastal-resiliency-and-water-quality-on-long-island.pdf

Reasons why outdated septic tanks are poorly affecting our environment

Many of the on-site systems in established communities are more than 40 years old, and as systems have aged, failure rates have increased dramatically, especially in the case where high groundwater conditions exist. As a result of the aging infrastructure issues including the decline in quality of drinking water, loss of wetlands, harmful algae blooms, and further impairing water bodies have increased.

Approximately seventy percent of Suffolk County's 1.5 million residents have an on-site sanitary wastewater treatment and disposal system. These systems are comprised of a septic tank or cesspool for solids, connected to leaching pools to allow clarified water to seep into the ground. Many of the on-site systems in established communities are more than 40 years old, and as systems have aged, failure rates have increased dramatically, especially in the case where high groundwater conditions exist. As a result of the aging infrastructure and the effects of Hurricane Sandy, the Suffolk County Comprehensive Water Resources Management plan found the following:

  • Gradual decline in quality of drinking water
  • Negative trends in quality of drinking water
  • Harmful algal blooms and Brown Tides attributed to excessive nutrient loads
  • Loss of wetlands is leading to a depleted coastal resiliency
  • Nitrification, impaired water bodies, impaired rivers, closed beaches, and devastation of the shellfish industry
