Doing business with Unitywater

Unitywater chooses to work with suppliers who are economically, environmentally and socially responsible to support the long-term wellbeing of our community.

Our policies and procedures ensure procurement of any good, service or construction activity is performed in an honest, competitive, fair and transparent manner.  We believe this delivers the best value-for-money outcome for our customers.

Supplier opportunities

We publish tendering opportunities through the Queensland Government’s QTenders website.

We don’t keep a register of interested or potential suppliers so if you’re interested in providing goods or services to us, please register your company details with QTenders. Once registered you will receive notifications of open invitations to offer that match your profile and provide you with access to tender opportunities.  We respectfully ask you do not cold call or email us.
