Your debris tank is full at 10 a.m.<\/b><\/p>\n

The nearest receiving facility is 90 minutes away. There may be a line at the gate. The excavation is only half done, but the hydrovac truck is about to spend the next three hours driving there and back before waiting time and unloading are even counted.<\/span><\/p>\n

For a contractor, that is the real slurry-management problem: an expensive, revenue-generating truck is hauling liquid instead of excavating.<\/span><\/p>\n

The disposal fee matters. So do truck turns, billable hours, productive excavation time, truck utilization and the space required to store or process wet material. The business case for any alternative should be measured against those operating constraints.<\/span><\/p>\n

The Cost Is the Disposal Cycle, Not Just the Disposal Fee<\/b><\/h2>\n

Hydrovac work is commonly priced by the hour, so every disposal run consumes time that could otherwise be spent on productive excavation. If the receiving facility is 90 minutes from the jobsite, the round trip alone is three hours. Add traffic, gate queues, discharge time and any processing delay, and one full debris tank can remove a large part of a shift from production.<\/span><\/p>\n

That cost is easy to miss when it is split across fuel, labour, truck time and disposal invoices. A better operating measure is the full disposal cycle:<\/span><\/p>\n

\"Hydrovac<\/p>\n

Then multiply that by the number of loads moved in a day or week. The same calculation can be used to compare a current wet-slurry workflow with an on-site solidification workflow.<\/span><\/p>\n

One hydrovac project provides a concrete example. On that project, hydrovac trucks offloaded into a lined roll-off bin for on-site solidification. MetaFLO reported savings of approximately $2,000 per truck load and about $6,000 per day based on an average of three hydrovac loads per day. The project also reported that one hydrovac truck could remain focused on the daily excavation work rather than leaving the site to dispose of liquid soil. Those figures are project-specific, but they show why truck utilization can be as important as the disposal rate itself.<\/span><\/p>\n

Why Wet Slurry Restricts the Operation<\/b><\/h2>\n

Hydrovac slurry contains soil, fines and water. While it remains flowable, it can require liquid-compatible containment, transport and receiving infrastructure. In Ontario, the regulatory definition of liquid soil is based on a slump of more than 150 mm under the prescribed test, not simply on the presence of free water.<\/span><\/p>\n

Operationally, wet slurry can create four recurring constraints:<\/span><\/p>\n
