Water NZ Pressure Sewer Good Practice Guidelines

Annual Conference

In the past 10 years, a significant number of Pressure Sewer Systems have been implemented across New Zealand (NZ). To provide technical consistency, share learnings and promote good engineering practice Water New Zealand and the Water Services Managers Group have embarked on a project to develop National Good Practice Guidelines for Pressure Sewer Systems.

This paper will introduce the Good Practice Guidelines, including giving an overview of the scope and contents of the Guidelines. The Guidelines consist of four main components:

  • A Decision Tree Guide – to assist in the selection between Vacuum, Pressure or Gravity Sewer reticulation options;
  • Ownership Models & Policies – discussion of common ownership policies including aspects of right of access to properties, easements and service agreements. A generic policy document will be available;
  • Technical Issues – technical specifications & design approaches including reference material, technical specifications and design standards relevant to pressure sewer systems. The typical hydraulic design approaches and their limitations will be discussed.
  • Operation & Maintenance – this section collates and summarises operation & maintenance issues and benefits of pressure sewer systems. Mitigation measures and methodologies to address or manage known issues will be discussed.
  • The Good Practice Guidelines (and this paper) will be of interest to a wide range of NZ Water Industry practitioners, including Local Authority Wastewater Planners, Policy & Strategy Officers, Equipment Suppliers, Designers, Specifiers, Consultants and Land Developers.
