Concrete wash off and Slurry control

Failure to control your fresh concrete wash off can result in slurry going down your drains. This slurry can then harden and completely block the system potentially causing thousands of dollars to remove.

It’s vital to have wastewater and slurry controls in place before starting concrete work as it’s illegal to dispose of concrete waste and slurry through New Zealand’s stormwater systems. By dumping concrete waste or slurry into our stormwater systems, you create a highly toxic environment that can harm our precious aquatic ecosystems.

The Drain Company can handle all your concrete waste and slurry management needs, whether it’s a residential or commercial site, we have specialised vacuum trucks & equipment that can remove slurry and dispose of it off site in a safe and responsible way.

Concrete wash-off generally refers to the accidental or intentional washing off of concrete residue or spills from surfaces such as roads, driveways, or construction sites. Unlike washout, wash-off often occurs without proper containment, potentially leading to environmental pollution. Concrete washout, on the other hand, refers to the process of containing and managing the rinse water, slurry, and leftover concrete materials generated when washing out concrete trucks, mixers, or equipment after use. It is typically done in a designated area or container to prevent contaminants from entering the environment, especially water systems.
