Whanganui District Council disposes of wastewater to minimise the impact of urban activity on the environment.
The service is provided through a network of wastewater pipes – generally within the road reserve – which are connected to properties at the boundary. Wastewater is collected from these points, treated and then discharged to sea through the ocean outfall approximately 1.7 kilometres off South Beach.
Industrial premises are serviced through a controlled discharge regime under trade waste regulations.
Separate rural wastewater schemes are operated at Marybank and Mowhanau.
The following services are provided:
- Wastewater connections are provided at property boundaries.
- The service is available to all connected properties 99% of the time.
- Residential properties (except for those in restricted services zones) can discharge an unlimited volume of wastewater, 24 hours per day, seven days per week.
- Industrial wastewater is collected in accordance with individual industry agreements, and the Trade Wastes Bylaw 2018(PDF, 324KB).
- Information to assist with service locations are available on request through the automated BeforeUDig service. On-site assistance can also be requested through Customer Services at (06) 349 0001.
- Complaints/enquiries about service breakdown are responded to within four hours.
- Maintenance and operation of the network and facilities ensures functionality and availability of service.
We have a new wastewater treatment plant off Airport Road. The Council decided in 2016 that a new wastewater treatment plant was needed to replace an earlier failed plant.
