Our relationship with the Waikato River
Since 2002, the Waikato River has been part of Auckland’s water supply network. At present (February 2021), we have a treatment capacity of 175 million litres of water a day. Construction of a new water treatment plant neighbouring the existing plant in Tuakau will be done in stages to ensure we are able to cater for growth.
The images below show how our resource consents have progressed since 2002, and detail who draws water from the Waikato River and why.
Our current Waikato River resource consents
The resource consents that we currently hold are as follows:
- Resource consent number 960089.01.04 allows us to take up to 150 million litres of water a day at any time of the year
- Resource consent number 141825.01.01 (referred to as the seasonal water take consent) allows for us to take up to 100 million litres a day during the period 1 May to 30 September (inclusive); and 100 million litres a day during the period 1 October to 30 April (inclusive) when the 7-day rolling average flow of the Waikato River at Rangiriri exceeds 330.03 m3/second
- Resource consent number 142090.01.01 (referred to as the Hamilton City Council Water Allocation consent) allows for us to take up to 25 million litres a day (or such lesser volume as determined by Hamilton City Council as being available for any given day) during the period 1 October to 30 April (inclusive). This is a short-term consent until 1 May 2023.
If our resource consent application for 150 million litres of water is granted, we propose that our 'seasonal water take' and 'Hamilton City Council water allocation' consents be surrendered. That would mean our year-round take from the river would not exceed 300 million litres a day.
The information below details our application to draw additional water from the Waikato River. The application is currently open for submissions.
