We have now gained the consents for the project and engaged Pipeline and Civil Limited to undertake the construction of the pump station. They are aiming to begin mid-2021. We will provide project updates to the community once a contractor is appointed and we have more details on the design and construction activities.
Why is it needed?
Sidmouth Street Pump Station receives wastewater from properties between Long Bay and Castor Bay and pumps it over East Coast Road to the Rosedale Wastewater Treatment Plant for treatment.
Due to an increase in population and wastewater, the current wastewater pump station is struggling to cope, particularly during heavy rainfall when diluted wastewater can overflow up to 10 times per year, approximately 70 metres out to sea at engineered points on either end of Mairangi Bay.
In 2014, we began a project to look at the best option for a replacement pump station and to work with Auckland Council to integrate planning with the reserve management plan at Mairangi Bay. In 2015, we presented a concept to the public for a replacement pump station. Since then, we have been looking at the best way to integrate the pump station design with the reserve surroundings while minimising environmental impact.
What are the benefits?
The new pump station will include larger pumps and technology to cope with wet weather flows, virtually eliminating overflows. The benefits include:
- Reduced wastewater overflows and improved beach water quality
- Cater for population growth in the area
- Improved open space and integration with the reserve
- New building architecturally designed to improve the visual appearance of the reserve
- New technology to manage and treat odour helping to reduce the total site footprint
