Before starting work on site you must:

• plan how to minimise the level of contaminants such as silt entering the excavation

• plan how to dispose of water that enters the excavation

• plan not to use machinery in excavations while dewatering is taking place

• minimise water entering the excavation, for example from rainfall, runoff, groundwater ingress or high water table

• consider using sustainable urban drainage construction methods
