Review of Environmental Factors

A Review of Environmental Factors (REF) will be required for any water or sewer construction works external to the development site, or where onsite construction activities may have environmental impacts that have not been addressed in the consent authorities assessment of the proposed development.

Examples where a REF may be required can include the construction of new or upgraded water and sewer mains, water and sewer pump stations, sewer vents, trunk mains, pressure sewer systems, PRV’s, reservoirs, development in a Wastewater Treatment Plant buffer zone, or development in a water reserve.

A REF considers the likely impacts the works may have on the environment and the local community. A number of stakeholders and government authorities may need to be consulted. This may include notifications and submissions made to Local Council or government authorities and consultation and/or notification undertaken with the local community or affected landowners.

The REF needs to be prepared in accordance with our Review of Environmental Factors REF Guidance Notes (found below) and is to include a preliminary project design. The Accredited Design Consultant for the works is responsible for coordinating the REF and ensuring consistency with the project design and is to submit the REF to Development.Planning@hunterwater.com.au .

A REF assessment fee needs to be paid when the REF is submitted for review and approval. Our team will contact you to make payment upon submission of the REF. The first review of the REF report is expected to be completed within 30 to 60 Days of payment being received - depending on the quality of the report and complexity of the scope of works.

The REF is to be submitted, reviewed and approved by Hunter Water prior to the Accredited Design Consultant submitting “For Construction” design documentation and the Design Compliance Certificate. Water & sewer construction works may not start prior to Hunter Water approval of the REF.
