MORE WATER FOR POWER
AUCKLAND, Oet. 28. After many difficulties and several years' work, tlie tunnel fxom .tlie Kaitawa kydro-electrie power station to Lake Waikaremoana kas reacKed the intake. strueture at the lake. This means that the full length of the tunnel has been driven, but other work on it is expected to take until the end of January to coniplete. The Kaitawa station is expected to be generating power by the spring of 1947. From portal to -intake strueture the tunnel is 1600 feet long, and it ineludes three curves in the last 700 feet, but there was less than a quarter of an inch error in the position of the tunnel where it emergjed. A channel has still to be dredged with a two-cubie-yard dragline exeavator from the intake strueture to the lake. Designed to provide a direet outflow from Waikaremoana to feed the hydroeleetric stations whieh are now dependent on water seeping from the lake through eraeks in the strata, the tunnel has been a troublesome undertaking.. Work was done on the scheme over ten years ago, but it was stopped in 1936 by the Minister of Works (Mr. Semple), who regarded it as unsafe. It was reeommenced after investigations, however, conerete being pumped into the rock ahead of the tunnellers to seal the fissures and eounter the dangers of flooding.
