Why is it important?

Water is a precious resource. Hamilton draws its municipal water from the Waikato River under a limited consent. To protect water security, Council needs to manage high-volume usage carefully. 

The HWUA helps Council: 

  • Manage water efficiently and sustainably 

  • Safeguard the mauri (life force) of the Waikato River 

  • Comply with resource consents 

  • Ensure reliable service for all residents and businesses 

If you use more than 15m³/day, you’re required under the Three Waters Connections Policy to enter into an agreement. 

Do I need one? 

You need an HWUA if you: 

  • Already use more than 15m³/day and intend to continue 

  • Are planning a new development or expanding operations that will exceed 15m³/day and/or 

  • Are planning to discharge more than 15m³/day wastewater into Council’s network 

If you’re reducing water usage below this threshold, you may not need an agreement — contact our team to discuss. 

How to Apply
