The Proposal

The Te Aranga Alliance, on behalf of Council, is leading the upgrade of the trunk sewer that runs through Bothamley Park. This project is deemed critical in improving our infrastructure to support planned growth in Porirua. It will also deliver significant environmental benefits through reducing the amount of untreated sewage overflow into the Kenepuru Stream that flows through Bothamley Park to Te Awarua-o-Porirua (Porirua Harbour). The upgrade will enhance the amenity of our open space network by locating more of the pipeline underground.

The project involves construction of approximately 3.5 kilometres of new trunk sewer, and retention of approximately 1.5 kilometres of the existing trunk sewer, as well as retention of several more kilometres of smaller-diameter branch sewers in the eastern parts of the park. Approximately 5 kilometers of existing pipeline will become redundant and will be either left in-situ or removed as part of the project. The focus here will be on minimising the impact to the environment and minimising any future risks.

The proposed upgrade will require closure of sections of Bothamley Park and Cannons Creek Park to protect the public and prevent access during the enabling works and construction phases. The areas affected by the proposed closures are used by the public for walking, dog walking, cycling and running.

The proposed construction approach is to stage the works to minimise disruption, with proposed rolling closures running from November 2022 till June 2025. Careful consideration has been given to the length of each section and the provision of alternative pedestrian routes for the duration of the closure for each section.

The indicative start date for works impacting on reserve land is November 2022 with a completion date of June 2025. These dates may change subject to consenting and/or unexpected delays. All efforts will be taken to minimise the length of time the reserves will need to be closed for this project.

The following measures are proposed to limit the impacts of the proposed closure on public access:

  • In some sections access paths will be closed for part of the work only,
  • Access to the blackberry harvest area will be opened during the blackberry harvest festival,
  • Diversion routes have been identified to provide an alternative route around closed portions of the parks, thereby connecting sections of path that remain open,
  • Park closures will be notified through a variety of channels well in advance, and diversions will be well signposted, and
  • The existing track on the north side of Kenepuru Stream will be upgraded to provide a 2.5-metre-wide gravel track for walkers and a possible alternative park run route.

If approved, a health and safety plan will be required to be approved by Council prior to works commencing for each section.
