SA Water together with McConnell Diona Joint Venture (MDJV) are installing a new water main to support growth in the Moana area.

Project Overview

The project involves installing 4.2 kilometres of new water main pipework along Tatachilla Road (from California Road to Main South Road), Maslin Beach Road, and the southern section of Commercial Road.

Snapshot of progress to date and current timing

We will update this section regularly, please watch for updates.

Repair Works - Commercial Rd, Maslin Beach Rd & Tatachilla Road

Starting week of 18 August 2025

With the majority of works nearing completion, we’re aware that several sections of the road require further reinstatement.

To address this, MDJV will return to site to undertake additional repair works, commencing in the week of Monday, 18 August (for up to 4 weeks). The following activities are planned:

Tatachilla Road:

  • Trench repairs will be completed on the majority of Tatachilla Road.

Maslin Beach Road:

  • Minor trench repairs will be completed on both the eastern and western sides of the quarry crossing.

Commercial Road:

  • Asphalt works are now complete, with further repairs scheduled for the southern end.



Kindly note that while dates are indicative of our project timeline, these may change depending on weather conditions and any technical constraints our teams may encounter.

How will project works affect you?

To ensure the safety of road users and our crews, traffic management will be in place throughout the repair works. This will include:

  • Reduced speed limits
  • Temporary stop requirements
  • One-lane closures in the active work zone and stop/go requirements for road-users.
  • Access will be provided at all times, including to driveways near the work area

These arrangements avoid the need for detours though may add time to your travels, so please plan accordingly. We appreciate your patience while these improvements are carried out and encourage drivers to follow all signage and directions from traffic controllers.

These works also require the use of noise generating machinery, hence construction activities may result in some noise and disruption impacts to nearby residents and businesses. Though construction noise cannot be avoided, where possible we will make every reasonable and practicable effort to minimise noise and disruption resulting from these works.

We will notify you in advance should any of these works require a planned and temporary disruption to your water supply.
