All extensions to Watercare’s water and wastewater networks must be designed and constructed in accordance with Watercare’s engineering standards.
The Water and Wastewater Code of Practice for Land Development and Subdivision applies region-wide. It is based on Standards New Zealand’s NZS 4404: 2010 and initially covers chapters five (wastewater) and six (water) of NZS 4404: 2010. In time, Watercare’s code of practice will be complemented by other chapters developed by the Auckland Council and Auckland Transport to cover their activities, in particular, stormwater and roads.
