Vendor quote
The Wastewater Facility has many flame arrestors built into the Anaerobic Digester
Complex. The purpose of these flame arrestors are to ensure if there is ever a failure in
the methane storage, use, or containment areas, flame does not get back to the biogas
distribution line, causing ignition.
The Wastewater department reached out to multiple companies, including Varec, Oceco,
Methuen Construction, and NEESCo for repair services. Each company offered either
replacement in kind parts, or repair services, only NEESCo offered repair services with
replacement in kind parts, making them the only company that can perform the services
as required.
NEESCo has already performed an emergency repair of the flame arrestor on the digester
complex waste gas flare this year.
