Wipes in the Pipes

Bathroom wipes are causing issues for city's wastewater facility.

In the grit chamber at the city of Keene’s wastewater treatment plant, a loud rumble fills the room as two 40,000 gallon tanks filled with water and sewage churn.

In this room, pieces of machinery called air diffusers inject air into the liquid so that sand, grit and inorganic material settle to the bottom of the tanks before the wastewater moves along for further purification.

This month, plant staff have been working to clean out the chamber, an annual process that can take up to a few weeks. The process involves draining the tanks and using a claw-like device called a clam shell to scoop up the inorganic material.
