First-of-it's-kind low carbon pipes installed at Auckland sinkhole

A new low-carbon stormwater pipe being installed today at the site of a sinkhole in central Auckland will be the first of its kind in New Zealand. In July, a 2.5 metre wide sinkhole appeared on College Hill after a stormwater pipe burst beneath the busy thoroughfare. It's just one of a string of recent issues with Auckland's ageing water network. It's hoped the new pipes will help to reduce the city's carbon footprint while also preventing future problems.
