Regional Specification for Water Services

The Regional Specification for Water Services  has been developed to consolidate the existing technical specifications for water services for Porirua, Lower Hutt, Upper Hutt and Wellington cities in order to provide a consistent method of design and construction of water services across the Wellington region.

The intention is to promote consistency in the local industry for the benefit of developers, designers, suppliers and councils.

The document is intended to be read in parallel with the Regional Standard for Water Services and the councils’ codes of practice for development, but relates only to infrastructure for stormwater, wastewater and water supply networks within the boundaries of the participating cities. It provides technical guidance for materials, construction and design.

It is intended that the provisions within this document shall be applied to the design and construction of proposed infrastructure in new subdivisions, and to the maintenance, renewal and upgrades of existing council infrastructure.

This specification may undergo occasional amendment as policy and technology evolves. The reader should ensure they are referring to the most recent version of the specifications.
