Good Practice Guide for Addressing Wet Weather Wastewater Network Overflow Performance

Water New Zealand have commissioned GHD to develop a Good Practice Guide (Guide) for the management of wastewater overflows in New Zealand. 

The primary purpose of this Guide is to provide a common framework for wastewater network service providers to implement, enabling a consistent approach to addressing wet weather wastewater overflows. This framework is centred around the incorporation of Te Mana o te Wai.
