Questions

Dewatering Plan: what people ask

Can I pump excavation water off a construction site?

Only with controls. Federal effluent guidelines prohibit discharges from dewatering, including trenches and excavations, unless they are managed by appropriate controls.

How often must dewatering be inspected?

Under EPA's 2022 Construction General Permit, once per day on which the dewatering discharge occurs. State permits may differ.

What goes in the dewatering record?

Within 24 hours: the date, inspectors, approximate start and end times, estimated rate in gallons per day, any sediment plume, unusual color, odor, foam or sheen, and photos of the water before and after treatment and of the discharge point.
