Construction of a detailed design - application process

Any significant modification to, or development and construction of local water utility water or sewage treatment works requires approval under Section 60 of the Local Government Act 1993. To apply for approval for construction of a utility's detailed design of the works, follow the steps below.

Step 1 – Initial consultation

Utilities are advised to consult with the department in the problem identification phase of the project as we can provide independent advice to help direct projects toward better and more cost-effective outcomes. We are committed to providing value to the process by sharing the extensive insights and experience it has gained through its ongoing oversight of the over 580 local water utility water and sewage treatment works in non-metropolitan NSW.

To begin initial consultation, contact us.

Step 2 – Options study

The utility is required to commission suitably qualified and experienced practitioners to prepare an options study report, identifying the most effective way to rectify the problem. The utility should:

  • involve the department in the early stages of the options study
  • provide the draft options study report to the department for comment
  • discuss comments with the department if required
  • arrange amendment of the report if required
  • provide the final draft report to thedepartment for endorsement.

The options study should include preliminary consideration of environmental and all other regulatory requirements relevant to the options. It should also identify all other supporting investigations and reports needed.

Utilities are encouraged to opt for cost-effective solutions that provide appropriate levels of service and value for money for the community.

Step 3 – Concept design and environmental impact assessment

After a preferred draft option has been selected, the utility should commission suitably qualified and experienced practitioners to prepare a concept design report. The concept design should be carried to such a stage where detailed design can be confidently based on the concept, and where only minimal further investigation is required. The utility should:

  • involve the department in the early stages of the concept design
  • provide the draft concept design report to the department for comment
  • discuss comments with the department if required
  • arrange amendment of the report if required
  • provide the final draft report to the department for endorsement.

The concept design should include detailed consideration of environmental and all other relevant regulatory requirements. Supporting investigations and reports identified in the option study, such as an environmental impact statement (also known as a review of environmental factors), should also be prepared.

Step 4 – Detailed design

The utility should commission suitably qualified and experienced practitioners to prepare a detailed design for construction, based on the concept design report. The utility should:

  • involve the department in the key aspects of process design beyond those included in the concept design report
  • provide the draft detailed design report to the department for comment
  • discuss comments with the department if required
  • arrange amendment of the report if required
  • provide the final draft report to the department for endorsement.

The detailed design should include information about:

  • process units
  • process and hydraulic flow (using diagrams)
  • process controls and instrumentation
  • wastewater management strategies.

Step 5 – Approval

Section 60 approval will be issued after the department has endorsed the amended detailed design. Project-specific conditions may apply.
