$500,000 donation to save gasholder raises hopes but doesn’t guarantee its future John Horangic of Bishop Brady High School joins the Save the Gasholder event on South Main Street on Dec. 29. GEOFF FORESTER / Monitor file Modified: 1/8/2021 4:55:19 PM An anonymous donation of $500,000 has given new hope to the idea of saving Concord’s gasholder, although the fate of the historic building is far from settled. The donation was announced Friday at the final meeting of the ad-hoc Gasholder Committee, which recommended that the city council accept a report outlining a multi-year, multi-million-dollar plan to save the building as a cornerstone of neighborhood development. The committee unanimously said Concord staff should begin discussions with the building’s owner, Liberty Utilities, about how to proceed.
