Large pipes and inlet structures can present safety risks. 

High head pressure combined with large water flow can create significant suction forces that could pull people or animals into the drain.  

Larger structures may be considered confined spaces.   Do not enter these structures without proper training and equipment.

People or animals could fall into structures and become trapped.  Locking lids are provided to prevent accidental access.   Keep these lids in place.

Use appropriate fencing and safety barriers to prevent accidental access. 

Working in a trench, ditch or hole is dangerous.

Only qualified individuals experienced in safe excavation practices should install these water level control boxes.

The sides of trenches can cave in unexpectedly.  Soil spoils can slide into the trench unexpectedly.  Soil is very dense and heavy – small amounts can easily bury or crush you leading to severe injury, suffocation or death.  Use appropriate precautions.  Follow safe excavation work practices.
