The Huntlee community is part of a recognised sustainable water network. As a result, homesites do not need rainwater tanks to meet BASIX requirements and are eligible for the highest water ratings. Find out more below.

No rainwater tank needed

Because this Hunter Valley community is part of the Huntlee sustainable water network, your new home is recognised for BASIX certification.

That means you do not need a rainwater tank to achieve BASIX, which will save you money.


The Building Sustainability Index, BASIX, is a web planning tool measuring the performance of new homes against water, energy and thermal benchmarks. It is administered by the Department of Planning and Environment.

Development Applications for residential dwellings, either a single dwelling or a multiunit, must be submitted with a BASIX Certificate. BASIX applies to new homes and home renovations of $50,000 or more.

BASIX requires all new homes in NSW to:

  • Use up to 40% less potable water
  • Produce up to 40% fewer greenhouse gas emissions than the average home.

The BASIX Water target incorporates regional variations such as soil type, climate, rainfall and evaporation rates.

The BASIX Energy target varies according to building type and location.

Each Development Application for a residential dwelling either a single dwelling or a multiunit, must be submitted with a BASIX Certificate. A Certificate is issued once a BASIX assessment has been satisfactorily completed, using the online tool on the BASIX website.

The homeowner, builder, architect or authorised agent is responsible for:

  • completing the assessment
  • ensuring the BASIX commitments are clearly marked on the plans
  • submitting the BASIX Certificate with the development application.

Eligible for highest BASIX rating

Because the Huntlee community is part of the sustainable water network it is recognised for BASIX certification and high ratings.

Recycled water can attract a 60 point rating from BASIX, helping the homeowner reach a higher score for their home.

BASIX Certification

All NSW homes need BASIX certification. The good news is that at Huntlee you don’t need a rainwater tank to meet requirements. When you or your builder go online to apply for BASIX certification:

  • Delete the requirement for a rainwater tank
  • Replace “Rainwater Tank” with “Alternative Reticulated Water Supply”.

Recycled water automatically gives you a higher BASIX score than rainwater tanks. And if you also install approved water savings devices in your toilet, bathroom, kitchen and laundry you will be eligible for the highest BASIX water rating.
