Point 8 – Sewage

Sewage input to the Jones Road treatment station should be limited to that from the Whangateau Catchment only.

An upgraded wastewater system is being installed in Matakana which pipes it all into the Whangateau Harbour catchment - Ian Macdonald


Reasons: The Whangateau Harbour environment is of uniquely high quality in the Auckland Region. Although the Jones Road treatment station operates to a very high standard, it is inevitable that nutrient loadings into the upper harbour will increase over the long term as a direct result of release, albeit indirect, of treated effluent into the water table, on to the golf course, and hence into the harbour, with long term enrichment results on the harbour. When the legitimate sources of sewage for the plant are all connected (existing Omaha, plus Point Wells, and possibly Whangateau) that will be sufficient in the long term for the Whangateau to cope with. There is little environmental justification to import sewage from another catchment (e.g. Matakana) just because in the short term it may seem convenient to do so.
