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.
The following map shows the final sections (work zones) of the alignment with current timing:

Snapshot of progress to date and current timing
We will update this section regularly, please watch for updates.
Commercial Road Anticipated return to usual operation: End-July-25 | Nightworks – Detours during nightworks are ongoing (see detour map section). Our moving work zone requires the closure of the southern section of Commercial Road on Sunday to Thursday nights from 8pm to 6am. This section of Commercial Road is available for regular use outside of these work hours. Final pavement treatments will be required. Dayworks – These works will not impact the road corridor and will be carried out as the project progresses within the reserve parallel to Commercial Road on Monday to Friday from 7am to 5pm. Early information on this stage of the project can be found in this letter (mid-April 2025). Notification of upcoming activities - Temporary supply outage around Karko Drive for 1 night shift - on Tuesday 10 June from 9pm to Wednesday 11 June 6am, some properties surrounding Karko Drive will be impacted by a supply outage.
- Properties which will be out of water during this time will be individually notified.
- Please note other properties on the outskirts of this area may also experience a reduction in water pressure. Thank you for your pateince while we complete these important works.
- Temporary supply outage around Sunset Drive for 1 night shift -on Thursday 19 June from 9pm to Friday 20 June 6am, some properties surrounding Sunset Drive may also be impacted by a supply outage.
- Properties which will be out of water during this time will be individually notified.
- Please note other properties on the outskirts of this area may also experience a reduction in water pressure. Thank you for your patience while we complete these important works.

Maslin Beach Road Anticipated return to usual operation: Mid-June-25 | Water main works are now complete, commissioning is required. Remaining pavement treatments are required. Reduced speed limits will remain in place until all reinstatement works are complete (including line-marking). No further detours or closures are required for Maslin Beach Road.

Tatachilla Road: Anticipated return to usual operation: Mid-June-25 | Water main works are now complete. Remaining pavement treatments are required. No further detours required. Reduced speed limits will remain in place until all reinstatement works are complete (including line-marking). |
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.
Note: Previous public-facing communications state works on Commercial Road will be completed by mid-July-25’
How will project works affect you?
Works will be completed in stages with road closures and detours required (noting strict local access only in some locations i.e. to properties with access points only within the work zone). Traffic management (including traffic controllers) and advance notification to road users will be in place.
These works 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.

Detour routes for nightworks on Commercial Road:


Please note:
- The Commercial Road work zone will be closed to traffic during nightworks only – traffic can access as usual throughout the day and Friday and Saturday nights.
- Due to it being a moving / progressive work zone, the areas will be impacted differently throughout the project and these will always be reflected in the traffic management in place.
- During nightworks, traffic controllers will accommodate strictly local traffic and 000 Emergency Vehicles only (meaning only road users who require access to driveways on the closed section of Commercial Road).
- Access to and from Sunset Drive will be accommodated at all times.
- Babbacombe Drive and Albany Way will remain open and accessible during nightworks, however detours (Maps 1 or 2 depending on works location) will need to be followed for access to/from the Southern end of Commercial Road.
- Once our work zone moves north of Sunset Drive and Seaside Boulevard, traffic will be permitted access to these streets from the south.
- The section that will be completed as day works is not within the road corridor, no traffic will be impacted (nor detours necessary) for this portion of the works.
- Bus detour information throughout the nightwork closures can be located here.
