There are serious water woes in the Wellington region and a multi-billion dollar price tag to fix them. The region has ageing, leaking pipes, sewage overflows, growing population and demand outstripping supply. The central government intends to establish a new national water regulator to oversee the water network, and reduce the number of authorities providing water. But in the meantime local councils are responsible for managing drinking water, wastewater and stormwater services. Kathryn speaks with Colin Crampton, Chief Executive of Wellington Water, owned by local councils in the region, about the massive challenges, including a network with 46 per cent of pipes described as "fragile".
