Southern Pipeline

The Southern Pipeline is a large wastewater pipeline that is needed to future-proof our city and protect our environment. It will give the city’s wastewater network some much-needed capacity which will reduce the risk of sewer overflows into the harbour.

The steady growth of our city is putting increasing pressure on the wastewater treatment plant at Chapel Street. This is a risk for both our city and environment, as it increases the potential for sewer overflows into the harbour. The Southern Pipeline will redirect some of the city’s wastewater to the treatment plant at Te Maunga, which has extra capacity. The new pipeline will relieve the enormous burden that is on the Chapel Street treatment plant, allowing the plant to improve its performance.

Construction began in 2009 and the pipeline is already operational from Maleme Street to Memorial Park. The section between Matapihi and Te Maunga is nearly finished, and the pipeline will be fully operational by end of 2018.

The projected final cost for the entire project sits at around $99 million.
