An increasingly popular service offered by EDC is the Hydro Excavation (Vac) system that can be applied to a multiple of uses throughout the constiuction industry.

EDC’s Hydrovac Excavation system offers many advantages when compared to traditional excavation machines. The system utilises high pressure water and vacuum technology to quickly and cleanly blast through soil, dirt, clay, gravel and rocks as well as other debris and materials while simultaneously being vacuumed into a holding tank for later disposal.

EDC’s Hydrovac system is used to expose services such as fibre optic, stormwater lines, electricity cables and sewer lines as well as opening ground for future cabling and structural work. Hydrovac Excavation has become the preferred form of excavation due to its non destructive and non-invasive process. Digging trenches using general excavation techniques also poses potential safety hazards when excavating around buried gas lines and hydraulic services. EDC’s Hydrovac system provides safe and accurate digging that limits the amount of damage of any pipework below.

Case Studies

Unley Council

When an external contractor accidentally dug through the Unley Council’s sub-terrain fibre cables they knew to call EDC’s Rapid Response number for urgent assistance.

EDC were able to isolate the damaged fibre cabling by using their Hydravac System. Rather than having to use mechanical diggers to acces the cabling, EDC were able to limit the damage done to surface area, and reduce the level of danger associated with earth moving machinery.

EDC found the affected cable, repaired it quickly and had the network up and running in record time.


With EDC very involvved with the GiGCity rollout and SABRENet, the Hydravac Excavation System allows EDC Crews to contain the level of disrupption usually associated with the laying of cabling in trenching.

The Hydravac allows EDC to dig trenches as narrow as 10cm in width with an accuraacy that means that surrounding landscaping is barely impacted upon. By digging trenches this way, the time taken to dig, lay and cover is greatly reduced allowing any disruption to be minimised.

Rundle Mall Security Upgrade

EDC have been involved with the upgrade of Rundle Mall since it began. With recent world events, Adelaide City Council has installed retractable bollards at all entrances to the Mall. Currently controlled by on-site security, EDC have been engaged to install fibre cabling to create a network that will allow for remote control of the bollards and monitoring of the City area with security cameras.

EDC will use their Hydravac System to dig the trenches and limit the damage and number of pavers that will need to be removed for this process. The speed of this proecess also means that Rundle Mall will have limited disruption to its flow of pedestrian traffic.
