Engineering Design Standards

Help shape Selwyn Water's new Engineering Design Standards

Selwyn Water is developing new Engineering Design Standards to update the current drinking water and wastewater infrastructure sections of the Selwyn District Council Engineering Code of Practice (ECOP).

As part of this process, we're seeking feedback from those who regularly use the current ECOP, including developers, consultants, engineers, contractors and surveyors.

Your feedback will help us:

  • Understand what's working well
  • Identify areas for improvement
  • Address common challenges and pain points
  • Develop new Selwyn Water Engineering Design Standards that are clear, practical and fit for purpose
  • Prepare for future alignment with the National Engineering Design Standards (NEDS)

Share your feedback

We invite you to review the water supply, wastewater reticulation, and general requirements sections of the current Engineering Code of Practice and share your feedback through a survey using the button below.

The survey is open until 5pm, Friday 21 August 2026.
