Collection System History
The City of Fairfield’s wastewater is collected by a network of private laterals and main sewers. With the help of 12 lift stations, the system flows by gravity to the Wastewater Treatment Facility. The City’s sewer collection system contains over 4,300 manholes and over 175 miles of sewer pipe in sizes ranging from 8 inches to 42 inches in diameter.
The collection crew completed recording the City’s entire sewer collection system on Video Cassette Recorder tapes. This gave the Wastewater Treatment facility visual access to every sewer line in the City.
Construction was completed on a 25 million gallons per day (MGD) Relief Sewer Pumping Station, 9 overflow structures, 4.6 miles of force main, and a 10 MGD equalization basin. This project was initiated to take the demand from the collection system during high flow events caused by heavy rainfall. The Relief Sewer Project has saved residents of the City hundreds of thousands of dollars in flood damage costs.
All of the Pump Stations’ Communications Systems were upgraded to Mission’s Communications. Mission’s Communications allows the Pump Stations to communicate with the Wastewater Treatment facility and/or the collection crew when the station has a problem. The Geographical Information System (GIS) was completed. GIS is the entire collection system, sewer lines, sewer laterals, lift stations, manholes, etc. mapped out and saved digitally.
The Happy Valley Drive Relief Sewer Project was completed. 3,436 feet of sewer pipe was installed from Happy Valley Court to Rolling Hills Swim Club in diameters ranging from 15 to 18 inches.
On-site generators were installed at Fairfield Village, Seward Road, Lake Manor, and Route 4 Pumping Stations to keep the stations up and running during power outages. Gilmore Road Pumping Station was completely renovated. A new Digital Video Sewer Inspection Television truck was purchased. The collection crew is currently working on digitally recording the entire sewer collection system.
On-site generators were installed at Homeward Way and Sugarland Pumping Stations.
Seward 1 Lift Station was relocated. The Lift Station was reconstructed with more pumping capacity in order to support economic development.
A new low pressure sanitary force main was installed on Gray Road. The force main system provides sanitary service to residents on Gray Road who are experiencing septic tank failures.
A sanitary relief sewer overflow structure and 900 feet of sanitary sewer pipe was installed near Ross Road and Woodridge Boulevard. The new Relief Sewer System added much needed capacity and eliminated the City of Fairfield's last active Sanitary Sewer Overflow (SSO).
Homeward Way Lift Station was reconstructed with more pumping capacity in order to support economic development.
Up To Date
There have been 305 Lining Projects consisting of 73,978 feet of sewer pipe being lined. 1,436 Manhole Rehabilitation Projects have been completed. The Rehabilitation Project and Lining Project prevent storm water from infiltrating the collection system.
The collection crew is hard at work on a number of different projects. The current Sanitary Sewer Cleaning Program has the City divided into 7 areas with the cleaning crew cleaning one area per calendar year. This allows the City’s entire sewer collection system to be cleaned once every 7 years. The video inspection crew is currently digitally recording the entire collection system, completing 70,000 to 90,000 feet of sewer pipe each year, with a goal set to complete by the year 2021. The crew also preforms 200 to 300 Miniature Camera inspections of residential sewer laterals per year. The collection crew is hard working and dedicated to serving the residents of Fairfield with pride.
