Napier City Council provides and maintains a safe, effective and efficient domestic wastewater collection, treatment and disposal system to help maintain community health. A separate industrial wastewater collection and disposal system is provided to selected trade waste customers.
Wastewater from Napier is collected and treated at the Wastewater Treatment Plant at Awatoto. It is pumped 1,500m offshore. The current concrete pipe, installed during the 1970s, has had issues since construction. Major leaks have been repaired in 1984, 2012 and 2020. With the pipe now considered end-of-life, the project to replace it is underway and expected to be completed in four years.
*Project costs are estimates.
To meet the conditions of Council’s wastewater discharge consent, we are undertaking a comprehensive review of our treatment processes with a focus on:
The review will consider the above with a lens on the new National Wastewater Environmental Performance Standards, and what additional treatment options will be to meet those standards. The standards are currently out for review and are intended to be published in August 2025.Â
Subsequent to the treatment review, Council will undertake a Wastewater Treatment Plant Master Plan review to refine treatment options, prioritise implementation, and provide budget forecasting to inform the 2026 Long Term Plan.
