Next, the wastewater flows through a grit chamber where sand and other heavy stuff sinks to the bottom. The grit is also moved to the landfills. The wastewater is slowed down as it moves through primary clarifiers. It is then allowed to settle so the tiny particle left in the cloudy water can either float to the top or sink to the
