Stormwater what you can do

A summary of our various stormwater projects.

New pump station in Bay View

We’re providing additional pumping capacity for Bay View during large rain events. This project depends on the stormwater modelling and master planning work to determine the details of the catchment layout and infrastructure needs.

Planned Start Date: Dec 2019
Construction Date: Dec 2020
Project Budget: $3.5M


CBD stormwater upgrade

We will complete the works required to upgrade capacity of the central business district stormwater pipes during larger rain events. This project depends on the Stormwater modelling and master planning work to determine the details of the catchment layout and infrastructure needs.

Planned Start Date: Dec 2019
Construction Date: Mar 2020
Project Budget: $1M


Ahuriri Estuary and Coastal Edge Masterplan

  1. Stormwater study: we’re undertaking a comprehensive stormwater study before researching or implementing other stormwater-related projects. This will help us to determine the feasibility of projects to better manage stormwater in the city.
  2. Pandora Catchment: together with at-source stormwater quality improvements carried out by individual businesses throughout the Pandora catchment, we are evaluating options for the preferred stormwater quality improvement works to the Thames and Tyne drains. We will look to add value through including education and recreation benefits.
  3. Direct outfalls: addressing stormwater quality at individual outfalls that flow directly into the estuary or coastal environment. Measures may include treatment devices, wetlands/swales, bio-retention systems, or screens. 
  4. Upper Catchment: improvements to stormwater quality entering the estuary from the upper catchment, including Bay View, Lagoon Farm, and the airport, as well as run off from rural residential areas of the western hills.

An initial sampling programme is being peer reviewed before work commences. The sample programme is looking at 21 sites across the catchment to enable better decision making in terms of education and treatment options. 

Planned Start Date: Already underway
Construction Date: Jan 2020
Project Budget: $6.2M
