 Although Croppers did not use the water from the reservoir, they decided to carry out repairs, which consisted of grouting of the foundations and crest of the dam; insertion of a liner into the scour pipe and a CCTV survey to prove its effectiveness; building a wall along the crest of the dam to prevent wave action damaging the downstream slope; removing silt from the tunnel through the downstream embankment; and grouting the spillway.A contract worth £100,125 was awarded to Askan Construction of Lancaster, with work commencing in August 1996.The liner consisted of a diameter HDPE pipe manufactured by Stewarts and Lloyds Plastic, and butt welded on site.
