Water & Sewer Construction Works

Shoalhaven Water undertakes audit inspections during the construction of infrastructure where it is intended to be transferred to Council’s ownership.

Pipe Inspection

Construction Inspections

Water and/or sewer construction works can form part of an approved development. Such works may be necessary to:

  • Provide infrastructure for the connection of the development to the water supply and/or sewerage systems,
  • Extend new infrastructure and connect the development to the water supply and/or sewerage systems,
  • Protect the existing water supply and/or sewerage systems,
  • Upgrade and/or augment the existing water supply and/or sewerage systems to support the approved development.

What design plans need to be submitted for consideration?

Water and sewerage design plans need to be prepared by a suitably qualified consultant to Shoalhaven Water’s specifications. Please refer to Guides, Resources and Standards for the documents used.

The designs plans need to show clearly:

  • What infrastructure is to be constructed,
  • What infrastructure is existing,
  • What infrastructure is to be modified,
  • Details of the development (eg, lot layout, contours, buildings and structures (existing and proposed), vegetation, other infrastructure, etc),
  • Construction notes, procedures, practices, etc,
  • Staging of work (if staged),

Other documents can include:

  • Work method statements,
  • Soil erosion and sedimentation control plan,
  • Detailed engineering calculations,
  • Detailed strategy reports.

When are design plans needed to be submitted?

Generally, water and/or sewerage design plans are submitted to Shoalhaven Water’s Projects/Development Unit prior to the issue of a Construction Certificate or a Subdivision Works Certificate.

The design plans need to be approved before a certificate can be issued.

Where a Complying Development Certificate is issued, then the design/s are prepared and approved prior to the commencement of any works.

Design plans can be submitted via email to: swdevelopment@shoalhaven.nsw.gov.au 

Shoalhaven Water charges a fee for the design checking and preparation of the design approval/s. This fee can be found in Shoalhaven City Council's Fees & Charges.

When can construction work commence?

Construction work may commence after:

  1. The design plan has been approved, and
  2. The pre-commencement matters as listed in the design approval have been satisfactorily completed to Shoalhaven Water’s satisfaction, and
  3. The pre-commencement meeting has been held on site, and
  4. The Shoalhaven Water officer or inspector permits for the work to commence.

What inspections are carried out by Shoalhaven Water?

Inspection of the water supply and/or sewerage works are required as the works are being constructed where it is intended for the works to be transferred to Council’s ownership. These specific inspections are listed within the design approval letter and may also be specified on the approved design plans. 

Inspections for water supply work include (but not limited to):

  • Materials to be used,
  • Disconnection of metered or unmetered services,
  • Before laying of pipes and other components,
  • Placement of sand bedding, pipeline, fittings, fixtures, sand backfill,
  • Placement long service conduits,
  • Assembly of fittings (eg, hydrants, stop valves),
  • Any other work relevant to the project, 
  • Pressure testing of the water main,
  • Restoration of site.

  • Testing of the sewer assets,
  • Restoration of site.

How do I book an inspection?

Water and Sewer inspections must be booked through Shoalhaven Water in accordance with the approval for the prospective works. Failure to arrange the required inspections will result in work not being approved and delays to the project which may involve excavation work to uncover the assets at the expense of the applicant/developer.

The lead time for an inspection type is specified on the approval document. Generally, there is a minimum 2 working days’ notice (prior to any works being carried out) for any inspection to occur.

Applications for inspections can be made:

Fees and Charges

Shoalhaven Water’s inspections are in addition to those inspections typically undertaken by the principal’s superintendent and are charged out in accordance with Council’s Fees and Charges.

Fees and charges apply to all inspections.

Work-As-Executed (WAE) plans

Submission of Work-As-Executed (WAE) plans

WAE plans are required to be prepared and submitted to show Shoalhaven Water the actual position of the constructed assets. The plan is recorded in our system and is used for future planning and maintenance purposes. The documents are also used to provide information to customers about Council’s assets.

WAE plans can be submitted via email: swdevelopment@shoalhaven.nsw.gov.au

Who prepares Work-As-Executed plans?

All WAE plans must be prepared by a registered surveyor in accordance with Shoalhaven Water's Survey Plan Preparation & Work-as-Executed document. This document is available for download off Shoalhaven Water’s website.
