Stopping the leaks (2nd of 2)

Stopping the leaks

The Public Works Department’s engineer-in-chief suggested that the government seek the advice of Swedish engineer P. G. Hornell on fixing the Arapuni dam. Hornell designed a complex, flexible lining of the dam’s headrace (the watercourse leading to the powerhouse). The lining consisted of steel plates, concrete slabs and a lot of bitumen. Hornell’s solution was not effective, and nor were the ongoing attempts to prevent seepage. In 2007 a two-year drilling project intended to stabilise fissures in the rock below the dam was completed.
