Wet Well

What is Wet Well?

A wet well is the underground chamber in a pump or lift station that collects wastewater or stormwater before it is pumped onward; vacuum and combo trucks pump out accumulated sludge and grit for maintenance.

A wet well holds incoming flow at a lift or pump station until pumps move it to the next stage of the system. Solids, grease, and grit settle in the well and must be periodically removed to protect the pumps and maintain capacity.

Cleaning a wet well typically uses a vacuum truck or combination truck to suction sludge and liquid into the debris body, sometimes paired with sewer jetting to break up buildup. Rent wet well cleaning equipment through a free Vac4Rent request and rental companies reply directly.
