Draft revision of the Regional Standard for Water Services and the Regional Specification for Water Services

Updated 26 May 2021

The Regional Standard for Water Services (RSWS) incorporates the Regional Specification for Water Services (R.Spec). Together, these two documents describe the minimum standards and specifications for the design and construction of stormwater, wastewater and water supply systems that will be vested in councils in the Wellington Region. The documents also include provisions for new connections to the networks as well as for maintenance, upgrade, renewal, and decommissioning of existing council infrastructure.

The standards and specifications provide a consistent method of design and construction for water services so that publicly owned assets are of good quality and fit for purpose. The RSWS and the R.Spec act as the “instructions” for how three waters networks are designed, constructed, operated and maintained.

Copies of the draft Standard and Specification, a Summary of Information Table and the Feedback Form are available below:

Why are we proposing this revision?

The Regional Standard for Water Services and Regional Specification for Water Services are revised on a regular basis to respond to changes in policy, best practice, technology, referenced standards and legislation.

This is the first major revision since the RSWS and R.Spec were compiled originally at the formation of Wellington Water. The revision in May 2019 was a minor revision.

This draft revision of the Regional Standard for Water Services and Regional Specification for Water Services also encompassed reformatting of the report-like documents to a format using numbered and multi-level paragraphs.

What’s changed?

All changes are described in a Summary of Information Table that is available here. In addition, all revisions to the requirements in the draft RSWS and R.Spec are shown in track/underline form.

The most significant revisions focus on the following matters:

  • Reformatting the documents to use numbered and multi-level paragraphs
  • Requirements for seismic resilience that address all three waters
  • Standards and specifications for building over or near public pipelines
  • The appropriate method for assessing hydrology
  • Consistency between stormwater level of service and mitigation requirements
  • Clearer provisions for pumping stations
  • Requirements for manhole safety grilles
  • Revisions to stormwater intake structures
  • Drawings are all now included in the R.Spec, including new drawings for backflow prevention and water supply assets.

In addition, revisions include:

  • Changes to reflect current accepted methods and policies
  • Reconciliation of overlaps between the Regional Standard and the Regional Specification
  • Removal of contradictions between the Regional Standard and the Regional Specification
  • Relocating information between the Regional Standard and the Regional Specification to ensure it is included in the correct document.

Are you also accepting feedback on the As-built Specification and Draughting Manual documents?

Yes. The As-built Specification and Draughting Manual are being released for alongside the Regional Standard and Specification. These documents are available to review above.

Why does this revision not address all previous requests?

The steering group for the Wellington Water Standards Team prioritises each request for resolution. Previous requests for revisions that are not addressed in this revision will be addressed in subsequent revisions.

What is the justification for each proposed change?

The Summary of Information Table here provides a description of each proposed change and the reason for the proposed change.

When do submission close?

Feedback and comments must be received by 5pm on Monday 28 June 2021.

What’s the best way to provide feedback?

What will happen to my feedback?

Feedback will be collated by the Wellington Water Standards Team and assessed by the steering group. Changes made as a result of the feedback will be added to the track/underline versions of the documents and feedback and decisions recorded in the Summary of Information Table. The final version (version 3.0) without track/underlining will then be adopted by Wellington Water and published online.

Please note that some requests for revisions may require more than the time and resources available for this revision and will be addressed in a subsequent revision.

When will Wellington Water finalise these revisions?

Following assessment of feedback on the draft documents, the final version 3.0 of the RSWS and R.Spec will be adopted prior to the end of 2021.

Is there an opportunity to appeal the final revision?

Although the final revision is not subject to appeal, the standards and specifications need to be continually updated to reflect changing policy, technology and best practice. Therefore, requests for revisions can be submitted at any time.
