Next Phase of the Infiltration and Inflow Study of the Farmington Sewer Shed

infiltration and inflow study

Please be advised that the Town has begun the next phase of our Infiltration and Inflow Study of our Farmington Sewer Shed. This phase is called the Sanitary Sewer Evaluation Survey (SSES).

Below are some project highlights:

  1. The project involves select neighborhoods and our main interceptor which conveys the sewer flows to Farmington – these neighborhoods were prioritized via the initial Infiltration & Inflow (I&I) project completed in 2019
  2. We will have letters/door hangers sent out to residents within the specific neighborhoods where we will be working.
  3. The project field work will primarily occur during the spring and early summer when groundwater is highest in both 2023 and 2024 and is somewhat weather dependent.
  4. Field work will include flow testing, manhole inspections, CCTV collection, and limited smoke testing and most of the field work will be performed at nighttime when flows from residences are typically low.
  5. Most of the system inspection lie within roadways, however there are portions of the system that run through private property.  The Town has easements over these areas providing legal access for the work.  Field workers will be respectful of property owners and will attempt to minimize impacts due to noise or other concerns.
  6. With very few exceptions, no field work will require field personnel to enter residences.  Whenever personnel are required to enter homes, residents will be notified in advance by Town of Avon staff so that a mutual meeting time can be established.
  7. All personnel working on the project will have proper identification and credentials.
  8. The area shaded in orange within the map indicates our Farmington sewer shed area.  Sewers and properties located outside of this shaded area are not included within the study.
  9. Questions or concerns may be addressed by either emailing Tim Foster, Avon’s Superintendent of Sanitary Sewers at TFoster@avonct.gov or by calling him at 860-409-4322.
