Regional Standard for Water Services

The Regional Standard for Water Services was developed to consolidate the existing codes of practice for water services for Porirua City, Hutt City, Upper Hutt City and Wellington City in order to provide a regionally consistent method of design and implementation of water services across the Wellington region that will meet Wellington Water’s 12 service goals.

The intention is to promote consistency in the local industry for the benefit of developers, designers, suppliers and councils. While the current format still has clauses particular to each city, the intention is that these differences will reduce over time as design philosophies consolidate with more collaboration.

The document is intended to be read in parallel with the Regional Specification for Water Services, and relates only to infrastructure for potable water, wastewater and stormwater networks within the boundaries of the participating cities. It provides overall objectives and performance criteria that proposed infrastructure projects shall comply with, and a set of standard design methods and general network component specifications.

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.
