Under the guidance of ARM, volunteers from Heathrow Airport, BAA Water Services, some apprentice engineers, and volunteers from Green Corridor turned up to help weed 2.1ha of reedbeds at the water treatment works at Mayfield Farm.

After the initial shock of discovering there are no goats or chickens at Mayfield 'Farm', the volunteers got stuck in weeding and planting at Heathrows wastewater Treatment works.
