This information is provided to assist land developers and consulting engineers with an understanding of the process for delivering infrastructure to a new land development.
Our Multi-staged development works manual and Developers’ manual provide a comprehensive, step-by-step guide for designing, constructing and handing over infrastructure assets for a land development.
You will need to follow these steps when developing land.
- Preliminary investigations into whether the concept and capacity of the proposed works are compatible with our overall planning requirements. Your design engineer will need to discuss with us:
- any alternative servicing intentions, such as if you are proposing a vacuum sewerage system instead of a gravity sewerage system.
- our requirements and any other authority’s requirements that will be imposed on the operation of the works.
- Develop a concept plan and submit for approval (multi-staged, broad-acre subdivisions only).
- Design works need to be submitted by a design engineer and must comply with our requirements.
- Submit initial design and documents to us.
- Prepare final submission, ensuring you comply with our final submission requirements.
- Receive all external approvals and prerequisites to works
- information on external approvals and the prerequisites to works process can be found in our external approval manual. All statutory requirements are outlined in the Water Services Act 2012.
- Submit final drawings and documentation to Water Corporation.
- will be valid for 12 months – if construction has not started in this period, the acceptance will lapse and you must re-submit
- any alterations to the design after acceptance must be discussed with us – a new submission may be necessary.
- Pre-start-up meeting requirements met – this includes providing the:
- name of the construction engineer and contact details
- name and contact details of the contractor and subcontractors
- contract price for the works
- proposed date for commencement of work.
- Start-up meeting should be arranged by the construction engineer with the asset inspector.
- Pre-construction requirements met – this includes providing:
- a Clearance to Works Permit (if required)
- proof the contractor has employed personnel with appropriate skills
- written notice to the occupiers of any property that will be affected by construction of the works – this should be given at least 10 days prior to commencement of work that will affect the property
- if electrical infrastructure, such as a distribution substation, is required for your land development, you may need to conduct an Earth Potential Rise (EPR) hazard assessment, obtain written approval confirming our acceptance of the proposed earthing design and submit the site verification test results to us for review and approval. Please refer to our Earth Potential Rise Manual for step-by-step guidelines on this process.
- you will need to adhere to our requirements during construction stage of the development process.
- Inspection of works during construction by our staff to ensure that all requirements are satisfied.
- Pre handover is completed by the construction engineer prior to booking a final handover inspection.
- the pre handover inspection checklist must be completed and given to the asset inspector with all test logs before the final takeover inspection.
- Final inspection by the asset inspector once the works have finished.
- Connection to existing Water Corporation infrastructure.
- Submission of as-constructed information.
- Takeover of infrastructure by Water Corporation.
- The warranty period is one year from the date of takeover. We will be responsible for operational maintenance of the works during this period.
- The developer is responsible for carrying out of any remedial repair and the cost of any consequential damage and claims due to faulty design, workmanship or materials during and after the warranty period.
- We will carry out any remedial repairs where the fault affects service to customers and public safety. The developer will be notified of this and will be charged for the cost.
- Final acceptance.
