Heavy rainfall and snow melt caused an estimated 858,000 gallons of partially treated sewage to discharge into Skaneateles Creek Sunday night over an 11-hour period, according to the NY-Alert system.
Discharging the sewer overflow took place around 9 p.m. Sunday night. Sewer overflow includes discharge from sewer systems bringing stormwater runoff, domestic sewage and industrial wastewater into the treatment facility, according to the state Department of Environmental Conservation.
The rain and snow melt caused excessive wet weather flows in the collection system, which exceeded the capacity of the sewer system. Excess water was discharged into the Skaneateles Creek.
The discharge location was 3831 Fennell Street, the village of Skaneateles' Wastewater Treatment Plant, and the discharge was partially treated with disinfection. To contain the discharge, the village has investigations scheduled for the spring and sewer televising and slip lining to reduce inflow.
In accordance with a 2013 state law, all publicly-owned treatment works and sewer systems must report combined sewer overflows to the DEC within two hours of discovery and to the public and adjoining municipalities within four hours.
Public notification is provided through the NY-Alert system, which can send messages direct through phone, email or text. Visit nyalert.gov online for instructions on how to sign up to receive alerts.
According to the DEC, sewer overflows can cause human and animal health hazards, water quality impacts, beach closures, algae growth, reduced oxygen levels in water and more.
