May 2019: The LFG System will be fully balanced by the end of May. Other than administrative close out procedures, the LFG construction project is complete.

April 2019: The Contractor has small site restoration and final project close out activities to complete. This system is fully operationsal and all indications are that capture, collection and combustion of LFG gases are in line with or exceeding expectations. Final performance and system balancing will be completed within the next 30-60 days.

March 2019: The Contractor has completed installation of the entire Landfill Gas Collection system. The system continues to combust LFG gas with methane concentrations that exceed 40% at a flow rate of over 500 square cubic feet per minute (scfm). The contractor has completed abandonment and removal of the old LFG system wells. Construction completion activities are finished; site restoration and final project close out activities will occur in March and we expect the project to be administratively completed by April of 2019.

February 2019: The Contractor has completed installation of the entire Landfill Gas Collection system.  All new wells are now active. The system is gathering and combusting LFG gas with methane concentrations that exceed 40% at a flow rate of over 500 square cubic feet per minute (scfm). The old system was collecting LFG gas that had a methane concentration in the high 20% range and at a flow rate of ~ 300 scfm. The contractor will spend February performing site restoration activities and abandonment and removal of the old LFG system wells. Substantial construction completion will be achieved this month, and the entire project and all work tasks should be finished by early March.

January 2019: The Contractor has completed installation of the main header and lateral gas piping on the entire southern half of the Landfill.  25 of the new wells are active and drawing gas, and the remaining 17 wells should be activated in February of 2019. Anticipated completion of all wells is February of 2019.

December 2018: The Contractor has completed installation of the main header and lateral gas piping on the entire northern half of the Landfill.  23 wells are now active, which about half of the 45 total LFG wells being connected to create the new system. Installation of the southern header piping began in November and will continue in December, along with installation of lateral collection piping. The goal is to activate another 5 new LFG wells by December 31, 2018. A construction oversight company has become involved to monitor the Contractors remaining progress due to how far behind they have fallen on the project. Anticipated completion at this point is February of 2019, weather dependent.

November 2018: The Contractor continues to install the main header and lateral gas piping on the northern half of the Landfill.  The contractor activated an additional 10 wells, which represents ~ half of the 42 new LFG wells being installed, with another 3 remaining and incorporated from the old system.

October 2018: 10 landfill gas wells have been connected for activation.  9 of the 10 new wells are currently active.  Laterals continue to be installed to connect another 10-13 new wells.

September 2018: The Contractor continues to install lateral gas piping in the northern half of the Landfill.  The main header piping has been installed on about 1/2 of the northern half of the landfill. The expectation is that the northern half of the new LFG system will be online and collecting gas by the end of October.

August 2018: Upgrades to the Landfill Flare and related components were completed by Perennial Energy of Missouri. These included a secondary blower system, related controls and chart recorder. Piping Installation continued.

July 2018: Main Header Piping and Laterial installation continued on the northern portion of the Landfill. Pressure testing of completed sections was conducted.

June 2018: The Main Piping Header and Lateral installation continued. Heavy Rains required additional excavation and remediation work on trenches.

May 2018: The LFG header on the northern half of the Landfill began to be installed. A tie in connection to the existing system was also completed.

April 2018: LFG well drilling activities were completed and the header and laterial installation began.

March 2018: Landfill Gas Well and Piping locations to be surveyed and marked out. Erosion control measures were installed. LFG Drilling started at the end of the month.  

February 2018: A notice to proceed with construction has been issued to the contractor, and the drilling rig and piping supplies have arrived.  Construction is expected to commence in March.

The Town of Manchester Landfill will begin a significant construction project in February of 2018. The project includes installing 42 brand new Landfill Gas Collection System (LFGCS) wells, constructing and installing a brand new header piping system, and making significant investments in the LFGCS Flare infrastructure.  The LFGCS is designed to capture nuisance odors through a vacuum mechanism before the gas reaches the atmosphere, and convey the gas to the Flare where is combusted at an average temperature of 1,400 to 1,500 degrees Fahrenheit to destroy odor causing chemical compounds.

The project is expected to take approximately 90 working days.  This webpage will serve to update the public on the progress of the construction and installation of the new LFGCS system.  Also, when there is active drilling and/or digging as part of the project, we will notify the public here as there is likely to be a noticeable increase in nuisance odors while digging and/or drilling is taking place.  The Town has an approved Landfill disruption permit from the Connecticut Department of Energy and Environmental Protection.

Upon completion of the project, it is estimated that 90-95% of the Landfill Gas that is currently being emitted by the Landfill mass/form will be captured and destroyed. For questions or concerns regarding the project, please contact Brooks W. Parker, Environmental Services Manager for the Manchester Landfill by email or by phone at 860-647-5279.
