Tunstall Reservoir
Facts and practical information
Tunstall Reservoir was a water supply storage reservoir completed in 1879, and now used solely to maintain minimum regulatory flows on the River Wear in northeast England. It is situated in the north Pennines of the United Kingdom, and lies 3.5 km north of the village of Wolsingham, in Weardale, County Durham. The earthen embankment dam, which impounds the reservoir, is recognized as the location where pressure grouting with cement grout was first utilized in 1876 by engineer Thomas Hawksley, to reduce leakage within the rock foundation under an earth dam. Pressure grouting has since become normal practice for construction and remediation at dams and related water resource projects. ()
