Glenfarg (Scottish Gaelic: Gleann Fairg) is a small village in the Ochil Hills in the county of Perth and Kinross, central Scotland. The village benefited from a station on the Perth to Kinross railway line until 14 June 1964, the line was closed to passengers and freight on 5 January 1970. The North British Railway experienced problems because of the landscape, which required 2 tunnels within 4 miles. The former railway line is now the route of the M90 motorway, which runs along the eastern periphery of the village. At its peak, the village became a popular holiday destination, boasting 4 hotels. Services in the village include a church, small shop, tennis courts, riding school, primary school with nursery, and a hotel, with a second recently having been bought out for housing development.
The 2008 construction work at Glenfarg Water Treatment Works won the accolade of "Most Considerate Site" at the 2009 Considerate Contractors Awards. The award was presented to the Black & Veatch Site Manager George Smart and the Scottish Water Solutions Project manager Steve Mason. This project also won 2 awards at the Scottish Water Awards 2009 "Delivering through Partnership" and "Outperforming the Capital Programme"
