Completed in June 2025, the Waingawa Process Water Project delivers a cost-effective, untreated water supply directly to businesses in the Waingawa Industrial Area.

The $2.77 million initiative repurposed a century-old water race, a 2500m³ storage tank, and a newly constructed pump station to draw water from the Waingawa River for industrial use.
Supported by $1.75 million in funding through Kānoa – Regional Economic Development & Investment Unit, and an additional $128,000 from the Wairarapa Economic Development Strategy (WEDS), the project delivers vital infrastructure to support local industry. It enables businesses to access process water for a range of non-potable applications, including manufacturing, steam generation, and equipment cleaning.

A key success for Council was the ability to use resources already in place to assist in project delivery. This avoided the need to drill a new borehole, instead repurposing the existing water race to fill the plant tank, with targeted infrastructure upgrades ensuring reliable delivery of water to end users. This approach maximised the use of existing assets while minimising environmental impact.

By leveraging existing resources and streamlining delivery systems, the project has potential to significantly reduce operational costs for participating businesses.

The Waingawa Process Water Plant is a practical example of how strategic investment and smart planning can deliver long-term economic and environmental benefits.

Connecting to the non-potable water supply is a cost-effective alternative to potable water supply for eligible businesses. The cost for this new supply is $1.25 per cubic metre, significantly lower than the potable water rates, which range from $2.78 to $3.22 per cubic metre depending on usage volume.

To apply for a connection, there is a one-off application fee of $242. Installation costs vary depending on your business site. Our Council team can provide guidance on what may be involved for your property.

Network infrastructure has been laid as far as budget allowed for during initial development. While not all businesses can connect immediately, we will work to expand the network in response to demonstrated demand. Feel free to contact our team at any time to discuss this initial stage, these conversations will help influence the next stage of development.

The non-potable water is provided at Pressure 6 Bar – Max Flow Rate 35 l/s
Non-potable water may still be restricted during droughts to prioritise essential services. Council will issue guidance during such events.

Usage will be metered in the same way as potable water supply. The same goes for billing.
