Maintaining public health and safety and having clean waterways is essential to the city’s environmental wellbeing.
Sewage collection and disposal is essential for public health and safety, and a core component of the city’s services. Without this service, Wellington could not operate as a modern, environmentally friendly city.
The city’s wastewater infrastructure is in good condition, and overflows of untreated wastewater into the environment are rare. However, our current resource consent for this activity (secured for the continuous operation of our wastewater treatment plants over the next 20-25 years) requires that we further reduce the amount and frequency of untreated wastewater overflows. We are progressing with a pilot programme to investigate and evaluate how private drains contribute to these overflows, construct a hydraulic model to more accurately identify sources of excess flows, repair private drains that contribute to the problem (until a policy is developed), and complete the development of overflow containment standards.
Our targets for 2013/14 are:
|2.4 Wastewater||Operating expenditure 2013–14||Capital expenditure |
|2.4.1 - Sewage collection and disposal network||(571)||18,167||17,596||7,411|
|2.4.2 - Sewage treatment||(639)||22,309||21,670||-|
|2013/14 2.4 Total||(1,210)||40,476||39,266||7,411|
|2012/13 2.4 Total||(1,252)||38,720||37,468||7,930|
