Kirikiriroa Integrated Catchment Management Plan

​What is the Kirikiriroa ICMP?

The Kirikiriroa ICMP will set out how the Council will manage water supply, wastewater services and stormwater within the Kirikiriroa Stream catchment.

Where is the Kirikiriroa Stream catchment?

The Kirikiriroa Stream drains from the east of the city and discharges into the Waikato River upstream of the Wairere Dr bridge.  The catchment spreads from the railway line at Ruakura in the south, to New Borman Rd in Rototuna north.  The western boundary runs through Five Cross Roads, St Paul's Collegiate, and the intersection of River Rd and Wairere Dr.  The eastern boundary generally lies near the Waikato Expressway, but extends east of the Expressway into Waikato District in places.  See the map below.


Why is the Council preparing the ICMP?

The ICMP will aim to manage land use and development, and the three waters (stormwater, water and wastewater) to:

  1. Promote sustainable management of the environment.
  2. Help achieve the Vision and Strategy for the Waikato River.  (See Schedule 2 of the Waikato-Tainui Raupatu Claims (Waikato River) Settlement Act 2010.)
  3. Comply with the Council's Comprehensive Stormwater Discharge Consent.
  4. Help the Council manage its three-waters assets.

What will be in the ICMP?

Once completed, the ICMP will provide guidance for existing and future development in the area and how:

  1. Stormwater runoff within the catchment will be managed to control erosion and flooding risk, and maintain, protect or enhance the Kirikiriroa Stream – including its water and sediment quality, aquatic and terrestrial ecosystems, and indigenous biodiversity. 
  2. The water supply network (pipelines, reservoirs and pumping stations) will be developed to accommodate population growth and ensure the required water volumes and pressure are delivered.
  3. The wastewater network (pipelines, pumping stations and wet-weather storage tanks) will be developed and managed to accommodate growth and ensure protection of public health, the Kirikiriroa Stream, and the Waikato River. 

The ICMP will also give effect to the relationship tangata whenua, as kaitiaki, have with the Stream and Waikato River.

How will the ICMP affect property owners?

The District Plan ( has rules requiring water supply, wastewater and stormwater infrastructure to be designed and constructed in accordance with any relevant ICMP.  New development within the catchment will need to comply with the Plan's rules and the ICMP. 

What could the ICMP require me to do?

The ICMP might require people developing land or building within the catchment to do things such as:

  1. Provide more green space.
  2. Build stormwater treatment devices, for example rain gardens or wetlands which will remove contaminants such as sediment, phosphorus, copper and zinc from stormwater.
  3. Collect rainfall and re-use it, dispose of it to ground soakage, or release it slowly, so streams don't get overwhelmed.
  4. Ensure new buildings are constructed above any predicted flood levels.

What else might be in the ICMP?

The ICMP might identify flooding on existing properties and projects to:

  1. Fix or prevent erosion in the Kirikiriroa Stream.
  2. Enhance habitat by planting trees.
  3. Extend water supply, wastewater and stormwater infrastructure.

How can I find out more about the project?

  1. Check out the project webpage at, which will be updated periodically.   
  2. Email with questions you might have or if you'd like to receive project updates.
  3. Phone the Project Manager, Paul Ryan on 838 6478.
