A major new water main is set to secure reliable drinking water supply for western Sydney residents well into the future — thanks to some clever engineering in the heart of one of the region’s most ambitious developments.
Located within the rapidly expanding Western Sydney Aerotropolis, Sydney Water and delivery partner John Holland are providing critical infrastructure to support the area’s booming population and economic growth. Central to this is the construction of one of the southern hemisphere’s most advanced wastewater recycling centres.
This state-of-the-art facility is part of the broader Upper South Creek (USC) project, designed to enhance environmental flows by directing treated water from the new Advanced Water Recycling Centre (AWRC) back into local waterways and drinking water supply.
To help deliver the treated water main for the USC project, contractor Jonishan used kwik-ZIP’s HDXT-103 spacers to slip-line a 914mm Sintakote® mild steel cement-lined carrier pipe into a 1200mm reinforced concrete jacking pipe casing.
Despite fully grouting the line, the HDXT spacers provided reliable long-term support for the pipe and the water it would carry.
The pipe weighs 292kg per metre when empty and up to 880kg per metre when full, so the feat was no small challenge. The HDXT spacer’s unique load-sharing design helped to distribute the load evenly across each runner, reducing point loading and allowing the system to handle the substantial weight.
Kwik-ZIP’s spacers are designed for fast, tool-free installation, making the process quicker and more efficient on-site.
The spacers are built to extend the lifespan of pipelines. With no metal parts that could corrode and a heavy-duty suspension system, they are well suited for high-load applications — especially when pipelines are filled with water.
Constructed from a tough engineered thermoplastic blend with a low friction coefficient, kwik-ZIP’s spacers are built to withstand tough conditions while supporting efficient installation.
They’re specifically designed to promote even grout flow and reduce the chance of voids. They lock securely in place using anti-slip rubber pads, ensuring correct spacing is maintained during installation.
With an emphasis on cost-effectiveness, straightforward assembly, and efficient on-site handling, kwik-ZIP’s spacer systems are engineered to provide their customers with significant time, cost, and performance benefits.
