Why the Connetquot River Sewer Project Is Important

Suffolk County Water Quality Initiatives

Suffolk County completed a Comprehensive Water Resources Management Plan in 2015. The plan clearly determined that nitrogen – which primarily comes from residential cesspools/septic systems and fertilizer – is the primary cause of harmful algal blooms, hypoxia, reduction in shellfisheries and the loss of wetlands and sea grass beds. The loss of wetlands and seagrass beds opens our coastal areas up to greater flooding because the presence of this native vegetation serves as a buffer and sponge to deter storm surge.

The County’s Comprehensive Water Resources Management Plan recommended four sewer projects along Long Island’s south shore rivers to help ameliorate the harmful environmental effects of nitrogen load along the:

  • Carlls River
  • Connetquot River
  • Forge River
  • Patchogue River
