On 1/22/2016, City staff installed a sump pump in the upstream manhole to minimize the amount of sewage flowing into the 16 inch diameter brick sewer. In addition the manhole was cleaned by a vacuum truck each morning. The City retained the Hartigan Co. who were on-site early on 1/25/2016 to inspect and clear the brick sewer. Early in the afternoon the blockage was found and removed. The City will slipline the brick sewer asap.

Description Of Incident:
|
On 1/21/2016, City staff became aware of sewage-like odors in the area of City Hall and West Canal Street. On 1/22/2016, the source of the odors was narrowed down to catch basins and where a stormwater systems discharges to the Winooski River downstream of the canoe access located near the CCRPC offices.
The source of the sewage was determined to be a 16 inch diameter brick sewer where a blockage caused by a combination of debris and grease caused ponded sewage (due to the blockage) to leak into the foundation drain of an adjacent apartment building. The foundation drain is connected to the stormwater collection system that discharges to the Winoosk River.
The start date is based on the date odors were first noticed. The end date is based on when the blockage was removed. The estimated volume is based on the possible number of connections to the sewer and the flow observed during the incident.
