SDG 6 Clean Water and Sanitation

Water usage in 2019 (our baseline year) was 185,591 cubic metres. Usage in 2024 was 18% below that baseline.

We are committed to protecting the environment and the health and safety of our communities. We adhere to the discharge requirements outlined in Section 15 of the Resource Management Act, the National Policy Statement for Freshwater Management 2020 (Amended January 2024), as well as regional water standard regulations and applicable resource and trade waste consents.

To prevent contamination, backflow prevention (inspected annually) is implemented across our Hamilton campus. Wastewater from our Science labs is monitored and audited by Hamilton City Council.

Our process for treating our wastewater is to make use of the local wastewater and stormwater network operated by Hamilton City Council, which follows sustainable policies that govern both the amount of water drawn from the Waikato River, Hamilton’s drinking water source, and the treatment of water discharged back into the river.

We have a Property Services Standard Brief that contains building standards for us to minimise water use in all new construction and to make sure the best energy, environmental and sustainable practices are adopted for campus design and construction. The Design Team is continually seeking new sustainable opportunities.

Digital M-Bus meters are required to be installed wherever appropriate on all major services. This means the water supplied is metered and communicated back to the Building Management System (BMS) by way of BACnet technology. Special attention is paid to fitting selection when considering general water installation, and water is to be re-used wherever possible. To minimise water use at all points appropriate, restricted volume taps and low-flow or dual-flush toilets are also employed.

Our Campus Masterplan (page 12) identified several opportunities to enhance the existing catchment, waterways, and lakes, and increase native planting. Principles outlined in the plan identify work towards the ecological enhancement of waterways, lakes and wetlands and prioritise ecological stormwater catchment systems, including reducing the amount of hard-paved areas. In our recent major building projects, the Tauranga CBD campus and our new landmark building on the Hamilton campus, The Pā, rainwater is collected off the roofs for greywater use.

Our two marine field stations (the Coastal Marine Field Station and Raukōkore Marine Research Centre), as well as conducting research, are also used for educating our communities. We regularly arrange visits and field trips for school and community group and host delegations from government ministries and regional agencies and associations. 

We actively promote conscious water use off-campus in the community through the Science Learning Hub with a range of 'Smart Water' initiatives to educate school children on water management, and Hamilton City Council to teach children the importance of valuing water.
