Project Summary

Blackstone Environmental assisted a local Municipal Solid Waste (MSW) landfill in overseeing the expansion of their landfill gas (LFG) collection system. Blackstone completed the design of the LFG system expansion and completed construction quality assurance (CQA) oversight and testing during construction. The expansion included the addition of vertical extraction wells, collection piping, and condensate collection sumps and was completed on a portion of the site which was relatively new waste. The LFG collection system produces methane for an on-site landfill gas-to-energy plant which produces pipeline quality natural gas.

Services Provided

Blackstone designed the LFG collection system expansion, which included new vertical extraction well design, re-drill of existing vertical extraction wells, header and lateral collection piping, condensate sumps, control valves, line maintenance valves and cleanouts, and wellhead flow control devices. Blackstone also conducted CQA services, which included inspection and observation of vertical well drilling, collection piping placement and pressure testing, and certification reporting.


The LFG collection system expansion project was completed in 2019 and was immediately turned on-line to help increase total LFG flow to the LFG-to-energy plant. The expansion area has improved LFG collection abilities across the site and has positioned the landfill to continue LFG collection services into the future.
