Sydney Water has restarted night works in Avalon along Old Barrenjoey Road as part of its ongoing water main upgrade project.
Works Resume In Avalon After Summer Pause
Construction resumed on Monday, 16 March 2026 after a pause in late November 2025 during the summer period. The earlier pause was introduced to reduce disruption during peak activity in Avalon and provide a break for nearby residents and businesses.
The project involves upgrading a 500-metre section of water infrastructure along Old Barrenjoey Road in Avalon Beach, including pipes, valves and hydrants.
Project Progress And Remaining Work In Avalon
Work on the upgrade began in March 2025, with a second stage commencing in early June 2025. Most of the new water main has already been installed using trenching and under-boring methods, along with smaller pipes to connect properties and fire services.
The remaining work in Avalon includes completing installation at the Avalon Parade intersection, followed by testing and cleaning the new pipe. Sydney Water will then connect the system, transfer services to the new main and decommission the existing pipeline.
Initial activity in March includes routine quality checks between The Crescent and Avalon Parade. These works may involve potholing and excavation.
Community Updates And Timeline
Sydney Water will continue monthly drop-in sessions for the Avalon community on the first Wednesday of each month from 2 p.m. to 4 p.m. at Dunbar Park. The next session is scheduled for Wednesday, 1 April 2026.
The project is currently targeted for completion by September 2026, depending on weather and ground conditions. Temporary restoration of affected areas will continue during the works, with permanent restoration planned after completion.
Night Work Schedule And Key Locations
Most work in Avalon will take place at night between 8 p.m. and 5 a.m., from Monday nights to Friday mornings. No work is scheduled on Friday, Saturday or Sunday nights, or on public holidays.
Construction will be concentrated at the Avalon Parade intersection, with additional stages planned near Barrenjoey Road and The Crescent later in 2026. Some daytime activity may occur for deliveries and site movements.
Traffic, Parking And Noise Impacts
Temporary traffic changes will be in place during work hours, with access maintained for residents, emergency services and waste collection vehicles.
A temporary compound has been re-established in the grassy area opposite 61 Old Barrenjoey Road. Some on-street parking along Old Barrenjoey Road, Avalon Parade and The Crescent may be used at times for work zones and storage. No car spaces are planned to be taken within the Woolworths car park.
Residents may hear construction noise during night works. Louder activities such as saw cutting and jackhammering are expected to finish by midnight, while excavation, backfilling and vacuum truck operations may continue until 5 a.m.
