Portaloos require regular cleaning, ideally weekly, depending on usage and the number of people using them. High traffic areas like construction sites or event facilities may require more frequent cleaning.

The most effective way to clean a culvert is using high-powered vacuum and water jetting equipment to remove built-up silt, debris, and blockages. This will ensure the culvert is fully cleared and water can flow freely again, preventing flooding and damage.
